Pharmacological and Therapeutic Potential of Cucumis callosus: a Novel Nutritional Powerhouse for the Management of Non-communicable Diseases.

Cucumis callosus (Kachri) is an under-exploited fruit of the Cucurbitaceae family, distributed majorly in the arid regions of India in the states of Haryana, Rajasthan, and Gujarat. The fruit is traditionally used by the native people at a small scale by home-level processing. It is a perennial herb that has been shown to possess therapeutic potential in certain disorders. In several studies, the antioxidant, anti-hyperlipidaemic, anti-diabetic, anti-cancerous, anti-microbial, and cardioprotective properties of Kachri have been reported. The fruit has a good nutritional value in terms of high percentages of protein, carbohydrates, essential fatty acids, phenols, and various phytochemicals. Also, gamma radiation treatment has been used on this crop to reduce total bacterial counts (TBC), ensuring safety from pathogens during the storage period of the fruit and its products. These facts lay down a foundation for the development of functional food formulations and nutraceuticals of medicinal value from this functionally rich crop. Processing of traditionally valuable arid region foods into functional foods and products can potentially increase the livelihood and nutritional security of people globally. Therefore, this review focuses on the therapeutic and pharmacological potentials of the Kachri fruit in the management of non-communicable diseases (NCDs) namely, diabetes, cancer, and hyperlipidemia.

Molecular docking and anti-ulcerative potential of Cucumis (L. Inodorous) on ibuprofen induced gastric ulceration in male wistar animals.

BACKGROUND: The use of NSAIDs have caused stomach injury by inhibiting endogenous mucosal prostaglandin production. Cucumis melo is reported to possess antiulcer potential. This study investigates the mechanism underlying the antiulcer potentials of Cucumis melo (CUM). METHODS: Thirty-five male Wistar rat were randomly assigned to each of seven groups; A(control given water and rat pellets), B(gastric ulcer induced with ibuprofen 400 mg/kg), C (Misoprotol 200 µg/kg), D to G (pretreated with different variation of CUM extract; 25 %, 50 %, 75 % and 100 % at a dose of 1 ml/kg for 3 weeks prior to gastric ulcer induction). Ulcer score, ulcer index and percentage inhibition, total gastric acidity was measured. Antioxidant activities, Malondialdehyde, H+/K+ ATPase, PGE2, TNF-α was done by spectrophotometry. Molecular docking investigation of Cucumis melo compounds against Prostaglandin E2 was carried out. Level of significance was tested at P ≤ 0.05 using Tukey post hoc. RESULT: Total gastric acidity, ulcer score, ulcer index, MDA, TNF-α significantly decreased after CUM treatment when compared to group B. The percentage inhibition, antioxidant activities, PGE2 concentration was significantly increased in all treatment groups compared to group B. Interactions of selected compounds of CUM with Prostaglandin E2 at various docking pockets showed folic acid has highest binding affinity followed by delta7-avenasterol and codisterol to PGE2 receptor. this study shows that one of the mechanisms by which CUM exhibits its antiulcer potential by enhancing Prostaglandin synthesis and antioxidant capacity. Therefore, Cucumis melo can therefore be explored as novel antiulcer agents.

Phytochemical evaluation of Cucumis prophetarum: protective effects against carrageenan-induced prostatitis in rats.

Phytochemical study of the MeOH extract of Cucumis prophetarum fruits (family Cucurbitaceae) by using different chromatographic techniques led to the isolation of three metabolites; spinasterol (1), cucurbitacin B (2), and 2-O-ß-D-glucopyranosylcucurbitacin E (3). Their chemical structures were created on the basis of physical, chemical, spectroscopic data 1D (1H and 13C NMR), and 2D NMR (HSQC and HMBC), as well as similarity with literature data. Cucurbitacin B (Cu-B) (2) was found to be the major constituent. Potential protective activities of MeOH extract, CHCl3, and EtOAc fractions and Cu-B were evaluated against carrageenan-induced prostatic inflammation in rats. Acute toxicity was assessed by evaluating LD50. Pretreatment with CHCl3 fraction and Cu-B ameliorated the rise in the prostate index and obviously protected against histopathological changes. Further, MeOH, extract, CHCl3, and EtOAc fractions as well as Cu-B significantly protected against oxidative stress in prostatic tissues. The anti-inflammatory activities of the extract, fractions and Cu-B were confirmed by ameliorating the rise in prostatic content of the inflammatory mediators TNF-α, IL-1ß, COX-2, and iNOS induced by carrageenan. In addition, the rise in the chemotactic factors were myeloperoxidase (MPO), F4-80, and monocyte chemoattractant protein-1 (MCP-1) was significantly hampered. In conclusion, three known compounds (1-3) were isolated from Cucumis prophetarum fruits. Cu-B (2) was the major identified compound. Particularly, CHCl3 fraction and isolated Cu-B exhibited potent anti-inflammatory activity against carrageenan-induced prostatitis. The anti-inflammatory activity can be attributed, at least partly, to inhibition of neutrophil and macrophage infiltration into prostatic tissues.

Structurally diverse coumarin-homoisoflavonoid derivatives with hepatoprotective activities from the fruits of Cucumis bisexualis.

Cucumis bisexualis is a favorite wild fruit with high nutritional and medicinal values because of its bioactive constituents. Four previously undescribed coumarin-homoisoflavonoid derivatives (1-4), together with seven known coumarin and homoisoflavonoid derivatives (5-11) were isolated from the fruits of C. bisexualis for the first time. All the compounds were elucidated by their extensive and comprehensive spectroscopic data and references. Compounds (1-11) were evaluated for their hepatoprotective activities in HepG2 cells by the acetaminophen (APAP)-induced damage model at 10.0 µM with bicyclol as the positive control. Among them, compounds 1, 3, 5, and 6 showed moderately hepatoprotective activities to improve the HepG2 cell survival rates from 51.68 ± 2.49% (APAP, 10 mM) to 71.55 ± 4.08%, 65.95 ± 4.39%, 60.77 ± 3.44%, 62.94 ± 2.30%, respectively.

Structural characterization and immunological activity of pectin polysaccharide from kiwano (Cucumis metuliferus) peels.

Two novel polysaccharides, namely CMPP-1 and CMPP-2, from kiwano (Cucumis metuliferus) peels were isolated through hot-water extraction, followed by ethanol precipitation and column chromatography. The results showed that CMPP-1 and CMPP-2 were hetero-galacturonans with different molecular weights of 7.35 kDa and 6.90 kDa, respectively. Both of CMPP-1 and CMPP-2 were mainly composed of glucuronic acid (45.93 % and 51.75 %, respectively), and other monosaccharides including rhamnose, arabinose, galactose, glucose, xylose, fucose, mannose, galacturonic acid, and mannuronic acid. The results of structural characterization from FT-IR and NMR confirmed that CMPP-1 and CMPP-2 were pectin with highly branched structure. Furthermore, both CMPP-1 and CMPP-2 possessed immune-enhancing activity and could enhance the secretion of nitric oxide and cytokines (TNF-α, IL-6) in a dose-dependent manner. Especially, CMPP-1 had higher immune activity than CMPP-2 as the minimum effective concentration were 0.78 µg/mL and 6.25 µg/mL, respectively. These findings provide a scientific basis for further utilization of polysaccharide from kiwano peels.

Nootropic Effects of C. melo and C. lanatus seed extracts.

Dementia and related conditions disturb the ability to perform routine life activities prohibiting a person from making appropriate decisions. Seeds of Cucumis melo and Citrullus lanatus have been investigated extensively for various pharmacological properties; hence, considering the presence of bioactive compounds, it was assumed that these seed extracts may support the functioning of the central nervous system. Thus, the present study was designed to investigate the short-term and long-term memory-enhancing effects of C. melo and C. lanatus seed extracts in mice by the Morris water maze (spatial learning and memory), stationary rod test, and passive avoidance tests (fear-motivated tests). Ethanol extract of both seeds were prepared by standard procedure and given to animals in the doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg. The results were compared to standard drugs diazepam and imipramine given in the doses of 3 mg/kg and 30 mg/kg, respectively. Extracts of both the seeds were found to possess significant memory and cognition-enhancing effects in mice when tested by passive avoidance, stationary rod, and water maze tests. Results demonstrate memory and cognition-enhancing effects of these extracts which may be due to the presence of bioactive compounds in these seeds.

Cervus and cucumis peptides combined umbilical cord mesenchymal stem cells therapy for rheumatoid arthritis.

Cervus and cucumis peptides (Lugua polypeptides, LG) are traditional Chinese medicine, which are active components of polypeptide extracted from Sika deer bone and melon seed, and they contain bone induced polypeptide biological factors. Umbilical cord mesenchymal stem cell, (UC-MSC) have tissue repair multiple effects, anti-inflammatory, and immune regulation function, which become a very promising start in rheumatoid arthritis (RA) treatment. Hence, LG combined UC-MSC can significantly enhance the UC-MSC treatment of rheumatoid arthritis (RA).To explore the clinical curative effect and therapeutic mechanism of LG combined UC-MSC for treating RA.119 patients were divided into control and treatment groups, and both groups were treated with methotrexate tablets, leflunomide, and UC-MSC. But, LG were added to the treatment group. In vitro, the effects of LG on UC-MSC cell secretion of anti-inflammatory factors were also performed.The Health Assessment Questionnaire; the 28 joint disease activity score; C reactive protein; the erythrocyte sedimentation rate; rheumatoid factor; and anti-cyclic citrullinated peptide antibody were significantly reduced in treatment group 1 year after treatment (P < .05). In vitro, compared with the control group, the number of hepatocyte growth factor (HGF), the secretion of prostaglandin E2 (PGE2) and tumor necrosis factor-inducible gene 6 protein (TSG6) increased significantly (P < .05).LG combined UC-MSCs can significantly improve the curative effect of RA patients, while LG may reduce inflammatory cytokines, regulate immunity, improve microcirculation, and are conducive to UC-MSCs migration and the repair of damaged tissue.

Hepatoprotective homoisoflavonoids from the fruits of Cucumis bisexualis.

Cucumis bisexualis has been widely served as a beneficial wild fruit in China. Four new homoisoflavonoids (1-4), together with eight known homoisoflavonoid derivatives (5-12) were isolated from the 90% EtOH extract of C. bisexualis, using repeated open column chromatography and preparative thin-layer chromatography. They were elucidated based on the analysis of spectral data and references from the fruits of C. bisexualis for the first time. These compounds (1-12) were evaluated for their in vitro inhibitory effects against the increase of aspartate aminotransferase and alanine aminotransferase levels in H2 O2 -induced HepG2 cells in the range of their maximum nontoxic concentration. Among them, compounds 3, 4, 8, and 9 exhibited certain hepatoprotective activities. PRACTICAL APPLICATIONS: Cucumis bisexualis A.M. Lu ＆ G.C. Wang is an edible and medical fruit with many functional properties. A detailed study was made to identify the bioactive constituents of C. bisexualis and four new homoisoflavonoids (1-4) and eight known homoisoflavonoid derivatives (5-12) were isolated from the fruits of C. bisexualis for the first time. Compounds 3, 4, 8, and 9 exhibited certain hepatoprotective activities. This study suggests that natural compounds isolated from C. bisexualis could be used as promising hepatoprotective agents.

Simultaneously quantitative analysis of peptides and chemical components in Cervus and Cucumis polypeptide injection (Songmeile®) using reversed phase liquid chromatography-hydrophilic interaction liquid chromatography-tandem mass spectrometry.

Co-occurrences of peptides and chemical components are usually observed in complicated matrices. Notably, those traditional Chinese medicine prescriptions (TCMPs) contain both plant and animal ingredients. It is still challenging to simultaneously monitor peptides and chemical components attributing to their different liquid chromatographic (LC) and mass spectrometric (MS) behaviors. Herein, efforts were made to pursue an eligible approach enabling simultaneous determination of peptides and chemical components in a TCMP namely Cervus and Cucumis polypeptide injection (CCPI, Songmeile®) that is prepared from the acid hydrolytic peptide-enriched extract of Sika deer (Cervus nippon Temminck) bone and the aqueous extract of muskmelon (Cucumis melo L.) seeds. Reversed phase liquid chromatography and hydrophilic interaction liquid chromatography were serially connected (RPLC-HILIC) to achieve comprehensive retention and separation. Sensitive detection was accomplished with selected reaction monitoring (SRM) mode, and multiply charged and singly charged ion transitions were defined for peptides and chemical components, respectively. Inter-batch variations of CCPI were evaluated in an authentic compound-independent manner. In particular, online energy-resolved MS was proposed to gain optimal parameters for five targeted peptides after that CCPI peptidome was profiled using nanoLC-LTQ Orbitrap Velos Pro MS. A so-called universal metabolome standard (UMS) sample was built for calibration curve construction and subsequently applied to acquire the quasi-contents of all 31 analytes, including five peptides and 26 chemical components, in ten batches of CCPI (CCPI1-CCPI10). The quantitative dataset revealed mild fluctuation for the quasi-content profiles of analytes-of-interest within different batches. More importantly, RPLC-HILIC-SRM is a promising method to fully address the demands of simultaneous measurement of peptides and chemical components in complicated matrices, and it might be a robust analytical tool for in-depth quality evaluation of CCPI as well as other TCMPs.

In vivo hepatoprotective and In vitro radical scavenging activities of Cucumis ficifolius A. rich root extract.

ETHNOPHARMACOLOGICAL RELEVANCE: Cucumis ficifolius A. Rich is a perennial prostrate herb that stems up to 1 m long. Its root is widely used in traditional medicine to treat various diseases including liver diseases. Yet, scientific evidence is lacking to verify its ethno medicinal claims. AIM OF THE STUDY: The present study was conducted to assess the hepatoprotective and radical scavenging activity of 80% methanol crude extract and different fractions of Cucumis ficifolius root. MATERIALS AND METHODS: Radical scavenging activity was done applying the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay while hepatoprotective activity was assessed using pre- and post-treatment models of carbon tetrachloride (CCl4)-induced liver injury in Swiss albino mice of either sex weighing 25-30 g. A single oral dose of 2000 mg/kg was used for acute toxicity study, doses of 125, 250, and 500 mg/kg were used in the pre-treatment model, and 500 mg/kg of extract and chloroform fraction were used in the post-treatment model. Biochemical markers and histopathological parameters were used to measure hepatoprotective activities. RESULTS: C. ficifolius crude extract and its solvent fractions showed strong radical scavenging activity and the chloroform fraction had the highest activity. No sign of toxicity was shown in an acute toxicity test of the extract. Hepatoprotective activity evaluation on the crude extract by a pre-treatment model with 125, 250, and 500 mg/kg doses revealed a significant (p < 0.05) reduction of the serum level of CCl4-induced liver enzyme markers at the highest tested dose (500 mg/kg). The chloroform fraction that had highest radical scavenging activity and the crude extract, both at 500 mg/kg, were again evaluated in a post-treatment model and the results revealed that both the extract and the chloroform fraction demonstrated significant (p < 0.05) hepatoprotective activities which support the results of the pre-treatment model. CONCLUSION: The present study verified the hepatoprotective potentials of C. ficifolius extract and its chloroform fraction which might be, at least in part, through radical scavenging action.

Isolation of anticancer constituents from Cucumis prophetarum var. prophetarum through bioassay-guided fractionation.

BACKGROUND: Cucumis prophetarum var. prophetarum is used in Saudi folk medicine for treating liver disorders and grows widely between Abha and Khamis Mushait City, Saudi Arabia. METHODS: Bioassay-guided fractionation and purification were used to isolate the main active constituents of Cucumis prophetarum var. prophetarum fruits. These compounds were structurally elucidated using NMR spectroscopy, mass spectral analyses and x-ray crystallography. All fractions, sub-fractions and pure compounds were screened for their anticancer activity against six cancer cell lines. RESULTS: The greatest cytotoxic activity was found to be in the ethyl acetate fraction, resulting in the isolation of five cucurbitacin compounds [E, B, D, F-25 acetate and Hexanorcucurbitacin D]. Among the cucurbitacins that were isolated and tested cucurbitacin B and E showed potent cytotoxicity activities against all six human cancer cell lines. CONCLUSION: Human breast cancer cell lines were found to be the most sensitive to cucurbitacins. Preliminary structure activity relationship (SAR) for cytotoxic activity of Cucurbitacins against human breast cancer cell line MDA-MB-231 has been reported.

Molecular Characterization and Bioactivity of Coumarin Derivatives from the Fruits of Cucumis bisexualis.

Cucumis bisexualis (Cucurbitaceae) is known as "mapao egg" or "muskmelon egg", which has been widely used as a wild melon in Chinese folk. Nine new coumarin derivatives (1-9), named 7-hydroxy-3-(4',6'-dihydroxy-5'-isopropyl-3″,3″-dimethyl-2 H-chromen)-6-prenyl-2 H-chro-men-2-one (1), 7-hydroxy-3-(5'-prenyl-3″,3″-dimethyl-2 H-chromen)-6-prenyl-2 H-chromen-2-one (2), 3-(6'-hydroxy-5'-prenyl-3″,3″-dimethyl-2 H-chromen)-6-prenyl-2 H-chromen-2-one (3), 3-(5'-ethyl-3″,3″-dimethyl-2 H-chromen)-6-prenyl-2 H-chromen-2-one (4), 3-(4',6'-dihydroxy-5'-dimeth-ylallyl-3″,3″-dimethyl-2 H-chromen)-6-prenyl-2 H-chromen-2-one (5), 3-[4',6'-dihydroxy-5'-(2-pro-penyl)-3″,3″-dimethyl-2 H-chromen]-14,15-dimethyl-pyrano-chromen-2-one (6), 3-(6'-dihydroxy-5'-isopropanol-3″,3″-dimethyl-2 H-chromen)-14,15-dimethyl-pyrano-chromen-2-one (7), 3-(5'-iso-pentenol-3″,3″-dimethyl-2 H-chromen)-14,15-dimethyl-pyrano-chromen-2-one (8), 3-(4',6'-dihydr-oxy-5'-prenyl-3″,3″-dimethyl-2 H-chromen)-14,15-dimethyl-pyrano-chromen-2-one (9), together with 12 known compounds (10-21), were isolated and identified by spectroscopic analysis and references from the active site (EtOAc soluble fraction) of the fruits of C. bisexualis for the first time. Compounds (1-21) were evaluated for antiacetylcholinesterase (AChE) and hepatoprotective activities for the first time. Compounds 1, 3, 5, 6, 7, and 9 showed anti-AChE activities with IC50 values ranging from 11.23 to 89.69 µM, and compounds 2, 4, 12, 15, 17, 18, and 19 (10 µM) exhibited moderate hepatoprotective activities. These findings shed much light on a better understanding of the anti-AChE and hepatoprotective effects of these coumarin derivatives and provided new insights into developing better anti-AChE and hepatoprotective drugs in the future.

Detection of NEO in muskmelon fruits inoculated with Fusarium sulphureum and its control by postharvest ozone treatment.

Fusarium rot of muskmelon, caused by Fusarium spp., is one of the most important postharvest decays, that not only causes economic losses but leads to trichothecenes contamination. A rapid and sensitive method was developed for neosolaniol (NEO) analysis in muskmelon inoculated with F. sulphureum, utilizing acetonitrile/water (84:16, v/v) extraction and PriboFast M270 columns purification and UPLC-MS/MS detection. Method validation was evaluated by linearity (R ≥ 0.9990), recovery (88.1-136.9%), precision (RSD ≤ 3.97%) and sensitivity (LOD, 0.5 µg/kg; LOQ, 1.5 µg/kg). The effect of ozone treatment on Fusarium rot development and NEO accumulation in inoculated muskmelon was also evaluated. The results showed that UPLC-MS/MS method was suitable for analyzing NEO in inoculated muskmelon, and 1.10 mg/l ozone treatment for 120 min significantly controlled Fusarium rot development and NEO accumulation in fruits after 5, 8 and 11 days. In vivo tests showed that ozone at 1.10 mg/l effectively degraded NEO in acetonitrile.

[Clinical analysis of cervus and cucumis polypeptide injection for lumbar vertebrae diseases based on real world hospital information system].

To analyze the clinical drug use characteristics and medication rules of cervus and cucumis polypeptide injection (CCP injection) for the patients with lumbar vertebra diseases. Based on the electronic medical data of 6 990 patients with CCP injection for lumbar vertebra diseases from 25 first-class hospitals over the whole country from 2004, statistical analysis was conducted for their general information, diagnostic information, orders information, laboratory test information and treatment results. The results showed that the age distribution was highest in patients aged 45 to 64 (3 883, 55.55%); protrusion of lumbar intervertebral disc was most common among lumbar vertebra diseases (5 519, 82.50%); and TCM syndrome mainly included hemostasis. The daily dose was most between 8-12 mL, with a usual treatment course of 1-3 d. Commonly used western medicines in combined drug use included hypertonic dehydrating agent, antibiotics and nutrition nerve medicines, and the commonly used traditional Chinese medicines in combined drug use included the drugs with promoting blood circulation to remove blood stasis, kidney-tonifying and bone-building agents, and formula for clearing heat and removing toxicity, etc. The most commonly used western medicines are methylamine, adenosine, lidocaine injection, mannitol, et al, and the most commonly used Chinese medicines included Jintiange capsules, Qianggu capsules, et al. It is suggested that CCP injection for lumbar vertebrae diseases is mainly used in middle-aged and elderly patients, and is frequently used in combination with kidney-tonifying and bone-building agents, drugs with promoting blood circulation to remove blood stasis, analgesic agents and antibiotics.

A comparative study of the antacid effect of some commonly consumed foods for hyperacidity in an artificial stomach model.

OBJECTIVES: The incorporation of certain alkalinizing vegetables, fruits, milk and its products in the diet has been known to alleviate hyperacidity. These foods help to restore the natural gastric balance and function, curb acid reflux, aid digestion, reduce the burning sensation due to hyperacidity and soothe the inflamed mucosa of the stomach. The present study evaluates and compares the antacid effect of broccoli, kale, radish, cucumber, lemon juice, cold milk and curd in an artificial stomach model. DESIGN: The pH of the test samples and their neutralizing effect on artificial gastric acid was determined and compared with that of water, the active control sodium bicarbonate and a marketed antacid preparation ENO. A modified model of Vatier's artificial stomach was used to determine the duration of consistent neutralization of artificial gastric acid by the test samples. The neutralizing capacity of the test samples was determined in vitro using the classical titration method of Fordtran. RESULTS: All test samples except lemon showed significantly higher (p<0.05 for cucumber and p<0.001 for the rest) acid neutralizing effect than water. All test samples also exhibited a significantly (p<0.001) higher duration of consistent neutralization and higher antacid capacity than water. Highest antacid activity was demonstrated by cold milk and broccoli which was comparable with ENO and sodium bicarbonate. CONCLUSION: It may be concluded that the natural food ingredients used in this study exhibited significant antacid activity, justifying their use as essential dietary components to counter hyperacidity.

Identification of all homoeologous chromosomes of newly synthetic allotetraploid Cucumis × hytivus and its wild parent reveals stable subgenome structure.

Allopolyploidy and homoeologous recombination are two important processes in reshaping genomes and generating evolutionary novelties. Newly formed allopolyploids usually display chromosomal perturbations as a result of pairing errors at meiosis. To understand mechanisms of stabilization of allopolyploid species derived from distant chromosome bases, we investigated mitotic stability of a synthetic Cucumis allotetraploid species in relation to meiosis chromosome behavior. The Cucumis × hytivus is an allotetraploid synthesized from interspecific hybridization between cucumber (Cucumis sativus, 2n = 14) and its wild relative Cucumis hystrix (2n = 24) followed by spontaneous chromosome doubling. In the present study, we analyzed the wild parent C. hystrix and the latest generation of C. hytivus using GISH (genomic in situ hybridization) and cross-species FISH (fluorescence in situ hybridization). The karyotype of C. hystrix was constructed with two methods using cucumber fosmid clones and repetitive sequences. Using repeat-element probe mix in two successive hybridizations allowed for routine identification of all 19 homoeologous chromosomes of allotetraploid C. hytivus. No aneuploids were identified in any C. hytivus individuals that were characterized, and no large-scale chromosomal rearrangements were identified in this synthetic allotetraploid. Meiotic irregularities, such as homoeologous pairing, were frequently observed, resulting in univalent and intergenomic multivalent formation. The relatively stable chromosome structure of the synthetic Cucumis allotetraploid may be explained by more deleterious chromosomal viable gametes compared with other allopolyploids. The knowledge of genetic and genomic information of Cucumis allotetraploid species could provide novel insights into the establishment of allopolyploids with different chromosome bases.

Synthesis of gold and silver nanoparticles using Mukia maderaspatna plant extract and its anticancer activity.

The present investigation reveals the in vitro cytotoxic effect of the biosynthesised metal nanoparticles on the MCF 7 breast cancer cell lines. The gold and silver nanoparticles were synthesised through an environmentally admissible route using the Mukia Maderaspatna plant extract. Initially, the biomolecules present in the plant extract were analysed using phytochemical analysis. Further, these biomolecules reduce the metal ion solution resulting from the formation of metal nanoparticles. The reaction parameters were optimised to control the size of nanoparticles which were confirmed by UV visible spectroscopy. Various instrumental techniques such as Fourier transform-infrared spectroscopy, high resolution transmission electron microscopy, energy dispersive X-ray and scanning electron microscopy were employed to characterise the synthesised gold and silver nanoparticles. The synthesised gold and silver nanoparticles were found to be 20-50 nm and were of different shapes including spherical, triangle and hexagonal. MTT and dual staining assays were carried out with different concentrations (1, 10, 25, 50 and 100 µg/ml) of gold and silver nanoparticles. The results show that the nanoparticles exhibited significant cytotoxic effects with IC 50 value of 44.8 µg/g for gold nanoparticles and 51.3 µg/g for silver nanoparticles. The observations in this study show that this can be developed as a promising nanomaterial in pharmaceutical and healthcare sector.

An insight study on HPTLC fingerprinting of Mukia maderaspatna: Mechanism of bioactive constituents in metal nanoparticle synthesis and its activity against human pathogens.

The present work reports the development of a Simple, rapid and eco-friendly route for the biosynthesis of gold and silver nanoparticles and their antimicrobial activity against gram positive and gram negative bacterial pathogens in the wound infected area. The synthesis was done using Mukia maderasapatna plant extract as a reducing agent. FT-IR analysis reported that the methanol extract was found to contain maximum number of functional groups which is responsible for the reduction of metal ions to metal nanoparticles. Further, the presence of bioactive molecules present in the methanol extract was confirmed by GC-MS analysis. The major phytochemical constituents observed in this Mukia maderaspatna leaf extract were n-hexadecanoic acid (15.51%), Octadecanoic acid (11.92%), stigmasterol (9.12%), Octadecanoic acid, 2, 3 hydroxypropyl ester (8.7%), Bicycloheptane, 2,6,6- trimethyl (5.57%) and stearic acid (4.23%). Initially, the formation of gold and silver nanoparticles was confirmed from their absorption spectra at 535 nm and 434 nm using UV- visible spectroscopy. The crystalline nature of the obtained gold and silver nanoparticles was confirmed by X-ray diffraction analysis. The average size of the gold and silver nanoparticles found around 50 nm and 20 nm respectively was confirmed by TEM analysis. The antimicrobial activities of silver and gold nanoparticles were checked against bacterial strains and the fungal strains. The formation of inhibition zones concluded that both the nanoparticles showed efficient antimicrobial activity against both the pathogens. Further, different concentrations of gold and silver nanoparticles, the antibiotics Ciprofloxacin and chloramphenicol as the positive control were carried out. The results concluded that the silver nanoparticles showed efficient activity against bacterial pathogens and fungal pathogens with the lowest concentration of 0.35 µg/ml and 0.45 µg/ml respectively.
