ABSTRACT
Hybrid structures made of natural-synthetic polymers have been interested due to high biological features combining promising physical-mechanical properties. In this research, a hybrid dressing consisting of a silk fibroin (SF)/polyvinyl alcohol (PVA) nanofibers and sodium alginate (SA)/gum tragacanth (GT) hydrogel incorporating cardamom extract as an antibacterial agent was prepared. Accordingly, SF was extracted from cocoons followed by electrospinning in blend form with PVA (SF/PVA ratio: 1:1) under the voltage of 18 kV and the distances of 15 cm. The SEM images confirmed the formation of uniform, bead free fibers with the average diameter of 199 ± 28 nm. FTIR and XRD results revealed the successful extraction of SF and preparation of mixed fibrous mats. Next, cardamom oil extract-loaded SA/GT hydrogel was prepared and the nanofibrous structure was placed on the surface of hydrogel. SEM analysis depicted the uniform morphology of hybrid structure with desirable matching between two layers. TGA analysis showed desired thermal stability. The swelling ratio was found to be 1251% after 24 h for the hybrid structure and the drug was released without any initial burst. MTT assay and cell attachment results showed favorable biocompatibility and cell proliferation on samples containing extract, and antibacterial activity values of 85.35% against S. aureus and 75% against E. coli were obtained as well. The results showed that the engineered hybrid nanofibrous-hydrogel film structure incorporating cardamom oil extract could be a promising candidate for wound healing applications and skin tissue engineering.

Hemp is probably one of the most studied plants for its health-promoting properties, with countless documented and patented extraction methods, but literature is scarce on the simultaneous extraction of mixture of raw materials. Hemp, along with other plant materials, could represent a potentially highly valuable source material with resulting reciprocal effects. In this study, hemp (Cannabis sativa) and three members of the Zingiberaceae family, ginger (Zingiber officinale), turmeric (Curcuma longa), and cardamom (Elettaria cardamomum), were extracted simultaneously, and their bioactive component values were investigated. Two extraction methods were used, namely ultrasound-assisted extraction with ethanol and supercritical fluid extraction with carbon dioxide. First, extracts were obtained from separate plant materials. Then, hemp was extracted in combination with ginger, turmeric, and cardamom in a 1:1 ratio. The extracts obtained were evaluated for their antioxidant activity and total phenolic content using UV/VIS spectrophotometry; cannabinoid content, 6-gingerol, and 6-shogaol were measured using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS); volatile components such as 1,8-cineole, alpha-terpinyl acetate, linalool, and aR-turmerone were measured using gas chromatography with mass spectrometry (GC/MS).

The chemical profiling of phenolic and terpenoid compounds in whole cardamom, skin, and seeds (Elettaria cardamomum (L.) Maton) showed 11 phenolics and 16 terpenoids, many of which are reported for the first time. Herein, we report the anti-inflammatory properties of a methanolic extract of whole cardamom in colon and macrophage cells stimulated with an inflammatory bacteria lipopolysaccharide (LPS). The results show that cardamom extracts lowered the expression of pro-inflammatory genes NFkß, TNFα, IL-6, and COX2 in colon cells by reducing reactive oxygen species (ROS) while not affecting LXRα. In macrophages, cardamom extracts lowered the expression of pro-inflammatory genes NFkß, TNFα, IL-6, and COX2 and decreased NO levels through a reduction in ROS and enhanced gene expression of nuclear receptors LXRα and PPARγ. The cardamom extracts in a range of 200-800 µg/mL did not show toxicity effects in colon or macrophage cells. The whole-cardamom methanolic extracts contained high levels of phenolics compounds (e.g., protocatechuic acid, caffeic acid, syringic acid, and 5-O-caffeoylquinic acid, among others) and are likely responsible for the anti-inflammatory and multifunctional effects observed in this study. The generated information suggests that cardamom may play a protective role against low-grade inflammation that can be the basis of future in vivo studies using mice models of inflammation and associated chronic diseases.

Cardamom Essential oils are highly demanded because of their antimicrobial, anti-inflammatory, and antioxidant activities. Nonetheless, retrieving quality extracts quickly with efficient energy savings has been challenging. Therefore, green technologies are emerging as possible alternatives. Thus, this study evaluates the yield and quality of the instant controlled pressure drop (DIC) process coupled with ultrasound-assisted extraction (UAE) of cardamom essential oil (CEO). Likewise, the antioxidant activity, chemical profile of CEO, and microstructure of seeds were analyzed. This study analyzed 13 different treatments with varying saturated steam processing temperatures (SSPT), thermal processing times (TPT), and 1 control. The results showed that CEO yield increased significantly by DIC (140 °C and 30 s) and UAE compared to the control (22.53% vs. 15.6%). DIC 2 (165 °C, 30 s) showed the highest DPPH inhibition (79.48%) and the best Trolox equivalent antioxidant capacity (TEAC) by the control with 0.60 uMTE/g. The GC/MS analysis showed 28 volatile constituents, withα-Terpinyl acetate, geranyl oleate, and oleic acid being the most abundant. DIC (140 °C and 30 s) and UAE showed the best yield and chemical profile. The SEM microscopy of untreated seeds revealed collapsed structures before the oil cell layer, which reduced the extraction yield, contrary to DIC-treated seeds, with more porous structures. Therefore, combining innovative extraction methods could solve the drawbacks of traditional extraction methods.

INTRODUCTION: Molecular diagnostics using RT-PCR has now emerged as the new diagnostic method for clinicians with the dawn of SARS-CoV-2. In India, the popularity and awareness of RT-PCR and particularly the increased availability of testing machines across hospitals has now opened up possibilities of diagnostic tests with RT-PCR. In view of the cytokine storm which is the significant reason for morbidity and mortality of COVID-19 patients, we proposed to test the usefulness of a multiplex RT-PCR test kit that simultaneously measured inflammatory markers namely, IL-6, TNF- α and IL-10 (IFM) all in one tube. The study included a group of patients who were equally allotted to two treatment arms one of which received standard of care along with a food supplement capsule as a natural anti-inflammatory (RECOVEREEZ FORTE™), and the other group received standard of care that included oral Prednisolone tablets in tapered dosage. RECOVEREEZ FORTE™ consists of potent biomolecules from cardamom extract. A natural product with substantial anti-inflammatory action when consumed early at the onset of symptoms is hereby proven by comparing gene expression profile of inflammatory markers with routinely tested inflammatory parameters such as serum IL-6, CRP and LDH. In addition to predicting worse disease outcomes beforehand, RT-PCR assay tests provides an opportunity for identifying therapeutic window aiding in practicing effective treatment strategy for COVID-19. RT-PCR analysis of IFM together being used in a single multiplex kit is being first reported and such a test as a prognosticator for disease progression does seem promising and worthy of clinicians adopting novel testing modalities in clinical practice. AIM OF THE STUDY: To study the anti-inflammatory response of RECOVEREEZ FORTE™ using RT-PCR based multiplex gene profiling of inflammatory markers in disease prognosis and show its predictability of worsening outcomes and its role in identifying therapeutic window for RECOVEREEZ FORTE™. To show the potentiality of RECOVEREEZ FORTE™ in reducing COVID-19 symptoms and SARS-CoV-2 RT-PCR Ct values of the treatment group. MATERIALS AND METHODS: This was a short study of a 10-day period where the end point was the negativity of COVID-19 on RT-PCR test or the decline in cycle threshold (Ct) values of the test performed on day 10 when compared to day 0. During the course of the study, patients were given standard treatment and an oral dose of 500 mg of RECOVEREEZ FORTE™ thrice daily, or standard of care and oral Prednisolone in tapered dosage (control group). All essential interventions were included in the standard of care as decided by the attending physician. The RT-PCR results of inflammatory markers were compared to routinely tested parameters such as IL-6, CRP and LDH. Time to clinical improvement was in terms of SARS-CoV-2 RT-PCR test negativity or recovery of COVID-19 symptoms. We enrolled 64 patients, of which 32 were allocated to RECOVEREEZ FORTE ™ group and 32 to the control group. RESULTS: The RT-PCR analysis of elevated IFM on day 0 corresponded to above normal protein levels of routinely tested parameters such as serum IL-6, CRP and LDH on day 5. Similarly, elevated IFM on day 5 corresponded to above normal protein levels on day 10. Such an association was equally prevalent in both the control group and RECOVEREEZ FORTE™ group, stipulating that RECOVEREEZ FORTE™ may be used as an alternative to steroids. The obtained results indicate that the RT-PCR assessment predicts worse outcomes 5 days earlier. But, the RT-PCR analysis of elevated IFM on day 0 did not correspond to the above normal protein levels of other parameters on day 10. Hence, indicating that the IFM RT-PCR test cannot predict worse outcomes 10 days earlier. Also, RECOVEREEZ FORTE™ when consumed for a period of 10 days normalized LDH values, compared to the control group. Moreover, IFM RT-PCR test identified a 5-day therapeutic window for RECOVEREEZ FORTE™ against inflammation experienced by patients. In addition to the above findings, the authors also observed that majority of the patients belonging to the treatment group showed recovery from symptoms such as fever, cough, sore throat and breathlessness compared to control group by day 5. 12 (37.5%) out of 32 patients and 6 (18.75%) out of 32 patients belonging to the treatment group and control group, respectively, became SARS-CoV-2 negative by day 5, indicating a probable anti-viral action of RECOVEREEZ FORTE™ against SARS-CoV-2. CONCLUSION: The IFM RT-PCR test possess 5-day early prediction ability and lacks 10-day prediction ability. Treatment with RECOVEREEZ FORTE™ indicates good anti-inflammatory action which is equivalent to steroids. Intake of RECOVEREEZ FORTE ™ for a period of 5 days depicts persistent anti-inflammatory action, recovery of COVID-19 symptoms and a probable anti-viral action. Moreover, an effective normalization of LDH may be rendered by RECOVEREEZ FORTE™ when consumed for a period of 10 days.

BACKGROUND: Herbs and spices are natural ingredients that have been widely used not just as food flavouring but also for their health attributes. The antioxidant, antimicrobial and anticancer components present in them enhance the health and medical status of human beings. The present study aims to produce Labneh fortified with cardamom and bay leaf powder to enhance the quality and shelf life. METHODS: Cardamom or bay leaf powder were added separately at the ratios of 0.25, 0.50, 0.75 and 1% (w/w) to Labneh and the treatments were compared with a control without cardamom or bay leaf powder during storage (at 5 ±1°C for 40 days). RESULTS: The total solids, fat, ash, carbohydrate and fiber contents were insignificantly higher in Labneh containing cardamom or bay leaf powder than control. The titratable acidity of Labneh gradually increased, whereas the pH values decreased by increasing the concentration of cardamom or bay leaf powder during the storage period. No significant differences were found in any textural parameters between Labneh containing condiments and control, except for that containing 1% cardamom or bay leaf powder, which exhibited higher hardness during the storage period. Minerals, antioxidants activity (RSA%), total phenolic (TPC) and total flavonoids content (TFC) increased with the increase of the added percentage of cardamom or bay leaf powder compared to control. Due to the stimulatory effect of cardamom and bay leaves on Lactic acid bacteria (LAB), the viability of the total bacterial count (TBC) gradually increased as the level of those condiments increased. The control became moldy after 10 days of cold storage while Labneh containing condiments remained unspoiled with yeasts and moulds for up to 30 days of cold storage. Sensory evaluation indicated that 1% addition of cardamom and 0.75% of bay leaf powder to Labneh improved quality and extends the shelf life of Labneh up to 30 days at 5 ±1°C. CONCLUSIONS: Labneh supplemented with cardamom or bay leaf powder can be considered as a novel product with acceptable quality and extended shelf life.

The chemical compositions of essential oils (EOs) prepared from six spices including cinnamon, amomum tsao-ko, cardamom, amomum, black pepper and white pepper were analyzed by gas chromatography-mass spectrometry (GC/MS), which led to identify almost 200 volatile compounds. All EOs of spices showed cholinesterase inhibitory activity. Among them, pepper EO showed most potent acetylcholinesterase (AChE) inhibitory activity with IC50 values of 8.54â µg/mL (black pepper EO) and 5.02â µg/mL (white pepper EO). Molecular docking and inâ vitro validation suggested that 3-carene, α-pinene and ß-pinene with IC50 value of 1.73, 2.66, and 14.75â µg/mL, respectively, might be active constituents of spices oil in inhibiting AChE. Furthermore, amomum tsao-ko EO and amomum EO can improve behavioral disorder in dementia zebrafish induced by aluminum trichloride (AlCl3 ).

ETHNOPHARMACOLOGICAL RELEVANCE: The dried fruits of Amomum subulatum Roxb. (A. subulatum) are widely used as a spice. It is a part of official ayurvedic formulations used in folklore medicine to treat cancer.A. subulatum has been used in ayurvedic formulations to treat various lung conditions such as cough, lung congestion, pulmonary tuberculosis. The present traditional knowledge highlights the effectiveness of A. subulatum in treating cancer and its lung-specific efficacy. AIM OF THE STUDY: This study aims to investigate the cytotoxic potential of A. subulatum on the phenomenal and mechanistic level of lung cancer cells and identify the presence of A. subulatum actives. MATERIALS AND METHODS: The bioactivity of the extracts was tested using MTT assay, apoptotic assay, cell cycle analysis, superoxide production assay, reactive oxygen species (ROS) assay, and western blot analysis. Firstly, five different extracts were prepared using sequential extraction, and then screening of cell lines was performed using MTT assay. RESULTS: Lung cancer cells were selected as the most sensitive target, and dichloromethane extract (DE) was the most active extract. Annexin assay confirmed the mode of cell death as apoptosis. SubG1 peak found in cell cycle analysis substantiated this finding. ROS generation and superoxide showed association with apoptotic death. The upregulation and overexpression of cleaved poly(ADP-ribose)polymerase-1 (PARP-1) showed the failure of DNA repairing machinery contributes to apoptosis. LC-MS findings show the presence of cytotoxic actives cardamonin and alpinetin. CONCLUSIONS: In summary, this study shows the apoptosis-inducing potential of A. subulatum fruit extracts and confirms DNA damage as one of the causes of cell death. Further explorations using bio-fractionation and in-vivo studies are required to determine the most active constituents in A. subulatum.

The present study examined the chemical composition and antimicrobial and gastrointestinal activity of the essential oils of Elettaria cardamomum (L.) Maton harvested in India (EC-I) and Guatemala (EC-G). Monoterpenes were present in higher concentration in EC-I (83.24%) than in EC-G (73.03%), whereas sesquiterpenes were present in a higher concentration in EC-G (18.35%) than in EC-I (9.27%). Minimum inhibitory concentrations (MICs) of 0.5 and 0.25 mg/mL were demonstrated against Pseudomonas aeruginosa in EC-G and EC-I, respectively, whereas MICs of 1 and 0.5 mg/mL were demonstrated against Escherichia coli in EC-G and EC-I, respectively. The treatment with control had the highest kill-time potential, whereas the treatment with oils had shorter kill-time. EC-I was observed to be more potent in the castor oil-induced diarrhea model than EC-G. At 100 and 200 mg/kg, P.O., EC-I exhibited 40% and 80% protection, respectively, and EC-G exhibited 20% and 60% protection, respectively, in mice, whereas loperamide (10 mg/kg, i.p., positive control) exhibited 100% protection. In the in vitro experiments, EC-I inhibited both carbachol (CCh, 1 µM) and high K+ (80 mM)-induced contractions at significantly lower concentrations than EC-G. Thus, EC-I significantly inhibited P. aeruginosa and E. coli and exhibited more potent antidiarrheal and antispasmodic effects than EC-G.

OBJECTIVE: The main objective of the study was to evaluate the cytotoxicity of selected essential oils on human skin, gastric, and brain cancer cell lines using microculture tetrazolium test. MATERIALS AND METHODS: Phytochemical analysis, as well as acute oral toxicity tests, was carried out in female albino mice with cardamom oil, lemon oil, and jasmine oil according to the Organization for Economic Co-operation and Development guidelines 425. Anticancer activities of the above test drugs were performed using human cancer cell lines. The studies were carried out at Skanda Life Sciences Pvt. Ltd., Bengaluru. RESULTS: Phytochemical analysis has shown the presence of carbohydrates and flavonoids in cardamom oil. While lemon oil has shown the presence of carbohydrates, flavonoids, steroids, terpenoids, and tannins, jasmine oil has shown the presence of carbohydrates, alkaloids, flavonoids, steroids, terpenoids, and glycosides. Toxicity studies showed that cardamom oil, lemon oil, and jasmine oil were all found to be safe up to 2000 mg/kg body weight. Results have shown that lemon oil exhibited the strongest cytotoxicity toward three human cancer cell lines, namely skin cancer (A431), gastric cancer (MKN-45), and brain cancer (U-87 MG) cell lines, with higher IC50 values of 62.82 µg/ml, 220.9 µg/ml, and 440.1 µg/ml compared to standard. Jasmine oil exhibited the strongest cytotoxicity toward skin cancer and brain cancer cell lines, whereas cardamom oil has shown stronger cytotoxicity only toward skin cancer cell line but did not show any level of inhibition of growth of brain and gastric cancer cells. CONCLUSION: Our study reveals that lemon oil, jasmine oil, and cardamom oil possess potent antitumor activity compared to standard. At different concentrations, lemon oil has shown statistically significant (***P < 0.0001) anticancer activity toward all the three human cancer cell lines. While jasmine oil has shown statistically significant (***P < 0.0001) anticancer activity toward skin and brain cancer cell line, cardamom oil has also shown statistically significant (***P < 0.0001) anticancer activity but only toward skin cancer cell line.

In the present investigation, the supercritical carbon dioxide (SC-CO2) extracts of small cardamom (SC) and yellow mustard (YM) seeds have been investigated for their efficacies in combating type 2 diabetes in streptozotocin-induced Wistar albino rats. Fasting blood glucose (FBG) levels in the rats were monitored on days 8, 15 and 21. On day 15, FBG level reduced appreciably by 31·49 % in rats treated with SC seed extract and by 32·28 % in rats treated with YM seed extract, comparable to metformin (30·70 %) and BGR-34 (a commercial polyherbal drug) (31·81 %) administered rats. Either extract exhibited desirable effects on hepatic glucose-6-phosphatase, glucose-6-phosphate dehydrogenase (G6PD) and catalase activities in controlling diabetes. A molecular docking exercise was conducted to identify specific compounds in the extracts which possessed augmenting effect on G6PD. The results revealed that all the bioactive compounds in the extracts have binding affinities with the enzyme and contributed to the antidiabetic efficacies of the extracts as G6PD augmenters. The effects of the extracts on insulin sensitivity and glucose uptake were investigated using non-invasive modelling by iHOMA2 software. This in vitro approach indicated that extract administration resulted in increased both insulin sensitivity of the liver and glucose uptake in the gut. The findings of the present study attest these SC-CO2 extracts of the spices as safe alternatives of metformin and BGR-34 in combating type 2 diabetes and could be safely subjected to clinical studies. These extracts could also be employed in designing proactive food supplements in mitigating the metabolic disorder.

In this work, the potential of chia seed mucilage (CSM) as a new source of carbohydrate for encapsulation of green cardamonmum Essential oils (GCEOs) was evaluated. 1H NMR spectrum, FTIR spectrum and, SEM image has confirmed the existence of the GCEOs in the nanofibers. The nanofibers of CSM and polyvinyl alcohol have not antibacterial property, while nanofibers containing GCEOs show antibacterial activity against E. coli and S. aureus. Incorporating GCEOs in CSM nanofibers improved the antioxidant of the generated nanofibers. The amount of radical scavenging for the nanofibers containing 16 (mg/ml) of GCEOs was 18% and increasing the GCEOs concentration up to 64 (mg/ml) leads to grow the activity up to 41%. Thus, our studies indicate that nanofiber can be used as a novel antioxidant and antibacterial agent in the food and pharmaceutical industry.

Ellettaria cardamomum (Cardamom) is an excellent antioxidant and its phytochemicals possess astounding detox properties. The bioactives of E. cardamomum have low bioavailability due to complex molecular structure. The main aim of this research was to formulate the E. cardamomum loaded phytosomes to improve the bioavailability with better ACE inhibition potential. The phytosomes were prepared by thin layer hydration technique. Various synthetic parameters for formulation of phytosomes were optimized by response surface methodology. Formulated phytosomes were characterized through spectroscopically and their biological activities eg. ACE inhibition were also investigated. Resultantly, the optimal production of phytosomes was achieved with the equal quantity (300 mg) of E. cardamomum and phospholipids at the time of 20 minutes of hydration. UV-Visible spectra confirmed the chemical and physical interaction between phospholipid and bioactives functional groups. The optimized E. cardamomum phytosome had 71% of entrapment efficiency. The average vesicle size of phytosomes was 577.8 nm with polydispersity index 0.443. SEM analysis revealed that phytosomes were spherical in shape. The phytosomes of E. cardamomum showed higher antioxidant and antimicrobial activities than its crude extract. The ACE inhibition activity of phytosomes (46%) was enhanced than the crude extract (39 %).

BACKGROUND: Cardamom is the flavouring spices mainly cultivated all over the world. Apart from being used as the spice, it has many medicinal values. Therefore, the present study aimed to investigate the potential use of cardamom and its effects on the ability of learning, developmental, and various biochemical factors of Swiss-Webster mice offspring at different stages. METHODS: In this method, Swiss-Webster mice offspring at different stages were used for the analysis of biochemical factors. After the administration of cardamom orally, the pups were subjected to various tests for determining social and defense behaviors of males and females, anxiety behavior; locomotor and neuromuscular activities, haemotological parameters, and hormonal factors of males and females. RESULTS: The present findings indicate that the cardamom induced reduction in the social and defense behaviors of males and females, respectively, and also anxiety behavior. Interestingly, locomotor and neuromuscular activities decreased significantly. DISCUSSION: In addition, the packed cell volume, red blood count, hemoglobin content, AChE in forebrain, the testosterone in males and progesterone in females were observed to increase significantly, whereas the blood platelets and total white blood count decreased non-significantly. Through perinatal exposure, cardamom can pass through the placenta or/and lactation and reaches the fetus. Care must be taken when using cardamom and especially during pregnancy and lactation. CONCLUSION: The administration of cardamom enhances the ability of social, developmental, and various biochemical factors of Swiss-Webster mice offspring at different stages.

Elettaria cardamomum (L.) Maton prestigiously called as Indian cardamom and is mostly cultivated in south India at higher altitudes ranging from 900 to 1400 msl. The chemical composition of dry capsules essential oil of the four distinct varieties was chemo-profiled by gas chromatography-mass spectrometry (GC-MS). Results revealed a higher concentration of major monoterpene 1, 8-Cineole ranging between 28.94% and 34.91% in PV 1 and PV 2 varieties respectively. Other monoterpenes like α-Pinene, Sabinene, Linalool, α-Terpineol and Nerol were present considerable quantities in all of the four cardamom varieties. Two sesquiterpenic constituents namely, ç-Elemene and 1,6,10-dodecatrien-3-ol (Nerolidol) were identified in all varieties. Three ester constituents were also obtained in PV 1 in which α-Terpinyl acetate (26.68%) exhibited as a major ester constituent followed by Ocimenyl acetate (0.80%) and E5-Dodecenyl acetate (0.30%). This is the first published report on the phytochemical concentration of recent varieties of Indian cardamom.[Formula: see text].

The present study demonstrates the efficacies of synthetic 1,8-cineole and an 1,8-cineole-rich supercritical carbon dioxide (SC-CO2) extract of small cardamom seeds in preventing oligomerization of amyloid beta peptide (Aß42) and inhibiting iron-dependent oxyradical production in vitro. The oligomerization of Aß42 was monitored by thioflavin T assay and MALDI-TOF analysis of the oligomers. The iron-dependent production of oxygen free radicals was detected by fluorometric benzoate hydroxylation assay. We observed that both pure 1,8-cineole and 1,8-cineole-rich extract of small cardamom seeds at concentrations of 50 µM and 100 µM prevented the production of reactive hydroxyl radicals from a mixture of Fe2+ and ascorbate. However, the 1,8-cineole-rich extract of small cardamom seeds prevented in vitro Aß42 oligomerization more effectively vis-à-vis the synthetic (99% pure) 1,8-cineole. Additional study on SHSY5Y cells indicated that both pure 1,8-cineole and 1,8-cineole-rich SC-CO2 extract of small cardamom seeds prevented iron-dependent cell death. Since oxidative damage, Aß42 aggregation and loss of cell viability (iron-induced) are characteristics of onset of Alzheimer's disease pathology, our results suggest a putative therapeutic role of 1,8-cineole-rich extract of small cardamom seeds over pure 1,8-cineole in preventing this neurodegenerative disease.

AIM OF THE STUDY: This review aims to provide a critical and comprehensive evaluation of the traditional and current medical uses of E. cardamomum, and compare these applications with modern research studies. This critical review also discusses the botanical distribution, phytochemical constituents and biological activities of cardamom capsule extracts and essential oil. MATERIALS AND METHODS: An online survey was conducted of the traditional uses, phytochemical composition, and pharmacological applications of cardamom essential oil (CEO) and extracts. Pertinent data were obtained from several electronic scientific databases (Science Direct, Elsevier, Web of Science, PubMed, Springer, ACS publications, Taylor and Francis, Wiley On-line Library and Google Scholar), and additional information was obtained from textbooks and local prints and scripts. RESULTS: Cardamom fruits (capsules) are used widely as a spice and flavoring ingredient in foods, and are often recognized for their beneficial health properties. They are also used in fragrances. Phytochemical analyses have described important chemical constituents of cardamom including carbohydrates, proteins, minerals, lipids, essential oils, flavonoids, terpenoids and carotenoids. CEO has several biological roles including antioxidant, antidiabetic, antibacterial, anticancer, gastro-protective and insecticidal activities. CONCLUSION: The widespread availability and recommendation of synthetic compounds for addressing human health have several side effects besides higher costs. Hence, examining natural bioactive compounds is imperative. This review investigates and presents the pertinent information on cardamom and its traditional uses, as well as potential pharmacological properties of CEO and extracts. Additional research studies are needed to understand the mechanism of action of bioactive constituents.

Cardamom (Elettaria cardamomum) is a traditional aromatic plant for which several pharmacological properties have been associated. In this study, the antibacterial activity of two cardamom extracts (fruit and seeds), rich in volatile compounds, against major periodontal pathogens was evaluated. Moreover, the ability of the extracts to exert anti-inflammatory activity was tested. Both cardamom fruit and seed extracts exerted an antibacterial effect against Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, and Prevotella intermedia (minimum inhibitory concentrations: 0.5% [v/v], 0.25%, 0.062%, 0.125%, respectively and minimum bactericidal concentrations: 1%, 0.25%, 0.062%, 0.25%, respectively). The cell membrane of P. gingivalis was disrupted by a treatment with cardamom extracts suggesting the bactericidal mode of action. The extracts also inhibited biofilm formation although it correlated with a growth reduction. Moreover, the cardamom extracts significantly decreased the secretion of IL-1ß, TNF-α, and IL-8 by lipopolysaccharide-stimulated macrophages. Evidence were brought that the anti-inflammatory activity may result from inhibition of the NF-κB signaling pathway. This study is the first to provide evidence that cardamom fruit and seed extracts through their antibacterial and anti-inflammatory properties may be therapeutic agents of interest against periodontal infections.

Melatonin-rich and 1,8-cineole-rich extracts have been successfully obtained from yellow mustard (YM) and small cardamom (SC) seeds, respectively, employing green technology of supercritical CO2 (SC-CO2) extraction. Chemical profiling confirmed the presence of melatonin and 1,8-cineole and co-extractants in the respective extracts. Electron paramagnetic resonance spectroscopy attested strong antioxidant activities of the extracts foregoing pan-assay interference compounds involved in spectroscopic analysis. These extracts also exhibited synergistic efficacies greater than unity confirming antioxidant synergy among the co-extracted bioactives therein. To ascertain hypocholesterolaemic efficacies, these extracts were co-administered orally with Triton X (at the pre-optimised dose of 175 mg/kg body weight (BW)) to Wistar albino rats at doses of 550, 175 and 55 mg/kg BW. Serum total cholesterol levels in the rats were monitored on days 3, 7, 15 and 21. On day 21, total cholesterol level reduced appreciably by 49·44 % in rats treated with YM seed extract and by 48·95 % in rats treated with SC seed extract, comparable with atorvastatin-administered rats (51·09 %). Either extract demonstrated inhibitory effects on hepatic 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase activity. A molecular docking exercise identified specific compounds in the extracts which possessed binding affinities comparable with therapeutically used HMG-CoA reductase inhibitors. In silico and in vivo studies concertedly concluded that the consortium of bioactive components in the extracts cannot be considered as invalid metabolic panaceas and therefore these 'green' extracts could be safely subjected to clinical studies as preventive biotherapeutics for hypercholesterolaemia. These extracts could be consumed per se as hypocholesterolaemic supplements or could be ingredients of new spice-based therapeutic foods.

BACKGROUND & OBJECTIVES: In our previous investigation, oral administration of 1,8- cineole-rich supercritical carbon dioxide extract of small cardamom seeds in Wistar albino rats resulted in achieving normal fasting blood glucose (FBG) and serum cholesterol levels. The objective of this study was to further protect the aforesaid extract and to enhance its in vivo therapeutic efficacies in redressing type 2 diabetes and hypercholesterolemia, by encapsulating it as nanoliposomes. Patents related to nanoliposomes have been revised thoroughly. METHODS: PEGylated nanoliposomes of the aforesaid extract were formulated using soya phosphatidylcholine and Tween 80 by probe-sonication. These nanoliposomes were subjected to in vitro characterizations and were orally administered to Wistar albino rats at three different doses viz. 550, 175 and 55 mg/kg b.w. for detailed investigation of their antidiabetic and hypocholesterolemic efficacies. RESULTS: FT-IR, DSC and XRD analyses, HLB value (16), entrapment efficiency (84%) and release kinetics (obeying Higuchi model) revealed that the nanoliposomes were o/w type and were hydrophilic. They exhibited appreciable in vitro antioxidant potency (59% DPPH scavenging activity) owing to a synergistic consortium of antioxidants present therein. Oral administration of the liposomes in rats at 550 mg/kg b.w. could restore their normal FBG levels and serum lipid profiles on day 35, with desirable up-down regulations of related key enzymes. The iHOMA2 model could successfully predict the effects of nanoliposomes on insulin sensitivity and glucose uptake in rat liver and brain, respectively. CONCLUSION: Nanoliposome of 1,8-cineole rich extract of small cardamom seeds is a new biotherapeutic in redressing type 2 diabetes and hypercholesterolemia.
