Physiological and biochemical mechanisms of grain yield loss in fumitory (Fumaria parviflora Lam.) exposed to copper and drought stress.

Soil contamination with heavy metals adversely affects plants growth, development and metabolism in many parts of the world including arid and semi-arid regions. The aim of this study was to investigate the single and combined effects of drought and copper (Cu) stresses on seed yield, and biochemical traits of Fumaria parviflora in a split - factorial experiment at Research Field of Payam-E-Noor university of Kerman during 2019. The collected seeds from two Cu contaminated regions were evaluated under drought and Cu (0, 50, 150, 300, and 400 mg/kg) stresses. Drought stress levels were depletion of 50% (D1), 70% (D2) and 85% (D3) soil available water. The individual effects of drought and copper stresses were similar to each other as both reduced seed yield. The highest seed yield was observed at Cu concentration of 50 mg/kg under non-drought stress conditions. The maximum values of malondialdehyde (0.47 µmol/g), proline (2.45 µmol/g FW), total phenolics (188.99 mg GAE/g DW) and total flavonoids (22.1 mg QE/g DW) were observed at 400 mg/kg Cu treatment. However, the strongest antioxidant activity (83.95%) through DPPH assay, and the highest total soluble carbohydrate (115.23 mg/g DW) content were observed at 300 and 150 mg/kg Cu concentration under severe drought stress, respectively. The highest amount of anthocyanin (2.18 µmol/g FW) was observed at 300 mg/kg Cu and moderate drought stress. The findings of this study showed a high tolerance of F. parviflora plant to moderate drought stress and Cu exposure up to 150 mg/kg by modulating defense mechanisms, where grain yield was slightly lower than that of control. The results could also provide a criterion for the selection of tolerance species like F. parviflora for better acclimatization under Cu mines and/or agricultural contaminated soils subjected to drought stress.

Comparative analysis of the complete chloroplast genome of Papaveraceae to identify rearrangements within the Corydalis chloroplast genome.

Chloroplast genomes are valuable for inferring evolutionary relationships. We report the complete chloroplast genomes of 36 Corydalis spp. and one Fumaria species. We compared these genomes with 22 other taxa and investigated the genome structure, gene content, and evolutionary dynamics of the chloroplast genomes of 58 species, explored the structure, size, repeat sequences, and divergent hotspots of these genomes, conducted phylogenetic analysis, and identified nine types of chloroplast genome structures among Corydalis spp. The ndh gene family suffered inversion and rearrangement or was lost or pseudogenized throughout the chloroplast genomes of various Corydalis species. Analysis of five protein-coding genes revealed simple sequence repeats and repetitive sequences that can be potential molecular markers for species identification. Phylogenetic analysis revealed three subgenera in Corydalis. Subgenera Cremnocapnos and Sophorocapnos represented the Type 2 and 3 genome structures, respectively. Subgenus Corydalis included all types except type 3, suggesting that chloroplast genome structural diversity increased during its differentiation. Despite the explosive diversification of this subgenus, most endemic species collected from the Korean Peninsula shared only one type of genome structure, suggesting recent divergence. These findings will greatly improve our understanding of the chloroplast genome of Corydalis and may help develop effective molecular markers.

Effects of Chicory and Fumitory on Hot Flashes Among Breast Cancer Survivors: A Randomized, Double-Blind Placebo-Controlled Trial.

Objectives: Hot flashes are unpleasant long-term complications of breast cancer. This study aimed to evaluate the effects of a traditional Persian medicine containing extracts of Cichorium intybus L. (chicory) and Fumaria parviflora L. (Fumitory) extract syrup (CFS) compared with placebo when used as intended. Design: Randomized, double-blind, placebo-controlled clinical trial. Setting/Location: The Oncology Ward of Shahid Modarres Hospital (Tehran, Iran). Subjects: Breast cancer survivors undergoing hormone deprivation therapy. Interventions: Patients were randomly allocated to receive 5 mL CFS or placebo syrup three times a day, for 4 weeks. Outcome measures: The co-primary outcomes were self-reported daily hot flashes frequency and severity scores assessed using self-reported daily dairies, including 1 week of baseline data. Results: Of the 148 patients screened, 137 were eligible, and 96 were randomly allocated to receive either CFS (n = 48) or placebo (n = 48). All participants who returned their dairies were compliant and analyzed as randomized in the a priori per-protocol analysis. After 4 weeks of treatment, both the mean daily hot flashes frequency and severity score had reduced by 57% in the CFS group and 10% in the placebo group. The overall weekly mean daily hot flashes frequency (effect size ηp2 0.221, p < 0.001, n = 66) and severity scores (effect size ηp2 0.160, p = 0.001, n = 66) were significantly lower in the CFS group compared with the placebo group (one-within one-between repeated-measures analysis of variance adjusted for baseline). CFS was well tolerated, with similar proportions of serious and nonserious adverse events occurring in both groups. Conclusions: This is the first study to report the effects of chicory or fumitory for the treatment of hot flashes. The findings provide preliminary evidence that CFS can improve hot flashes in breast cancer survivors undergoing hormone deprivation therapy. More research is warranted to confirm its effectiveness, safety, and mechanisms of action. Clinical Trial Registration: IRCT20210226050506N1.

The pyrethroid insecticide permethrin confers hepatotoxicity through DNA damage and mitochondria-associated apoptosis induction in rat: Palliative benefits of Fumaria officinalis.

Permethrin (PER) is a pyrethroid pesticide that is extensively used as an insecticide in world because of its high activity and its low mammalian toxicity. The current study was conducted to investigate the protective action of Fumaria officinalis against PER-induced liver injury in male rats. However, HPLC-DAD showed the richness of 6 components in F. officinalis (F) including quercetin, ferulic acid, and naringenin which were the most abundant. Total polyphenols, total flavonoids, and condensed tannins were studied by phytochemical screening. In vitro, antioxidant properties showed that F. officinalis exhibited the highest DPPH radical, FRAP, and H2 O2 tests and total antioxidant capacity. Wistar rats were divided into four groups: negative control group (C), positive control group (F) (200 mg F. officinalis/kg BW), PER group (34.05 mg permethrin/kg BW), and PER + F group (34.05 mg permethrin/kg BW and 200 mg F. officinalis/kg BW). Oral administration of PER led to promote a decrease of body weight and Ca2+ -ATPases and Mg2+ -ATPases activities and an increase of plasma C-reactive protein level, transaminases, and hepatic ϒ-GT activities as well as hepatic and mitochondrial oxidative stress. An increase in plasma lactate-to pyruvate ratio and a reduction in complexes enzymes I, III, and IV activities were also observed. In addition, histoarchitecture of liver in PER-treated rats showed apoptosis and necrosis as confirmed by DNA fragmentation. F. officinalis significantly exerted hepatoprotective effect by modulating hepatic alteration and mitochondrial dysfunction as well as genotoxicity. This effect could be attributed to phenolics compounds such as polyphenols, condensed tannins, and flavonoids.

The effect of Fumaria parviflora on the expression of sexual hormones along with their receptors in testicles of adult rats induced by varicocele.

Varicocele (VCL) is a pathological dilation of the venous pampiniform plexus of the spermatic cord and is also classified as male factor infertility. The current experiment aimed to examine the protective effect of Fumaria parviflora (FP), as a powerful antioxidant, against reproductive damage induced by VCL. In this experimental study, 32 male rats were randomly allocated into four groups, namely sham (simple laparotomy without additional intervention), FP (healthy rats administered 250 mg/kg FP), VCL + FP (underwent VCL and received 250 mg/kg FP), VCL (underwent VCL without receiving any treatment). The results showed that the number of Sertoli and germ cells were markedly reduced in the VCL group in comparison to the FP-treated and sham groups. The VCl + FP group had significantly higher serum levels of testosterone (T), FSH, and LH hormones than the VCL group. The quality and motility of spermatozoa were reduced in the VCL group compared with other groups (p ≤ 0.05). Moreover, our findings demonstrated that the administration of FP considerably enhanced the mRNA levels of CatSper-1 and -2, SF-1, 3ß-HSD, 17ß-HSD3, LHCGR, and FSHR (p ≤ 0.05). Based on the obtained results, treatment with FP is capable of preventing testicular dysfunction and elevating the concentration of hormones and some crucial genes, such as CatSper1 and 2, SF-1, 3ß-HSD, 17ß-HSD3, LHCGR, and FSHR that contribute to the spermatogenesis process.

Cardioprotective Potential of Aqueous Extract of Fumaria indica on Isoproterenol-Induced Myocardial Infarction in SD Rats.

Ischemic heart disease (IHD) treatments and preventions by using plant extract and its phytochemical constituents have achieved considerable attention globally due to its cardioprotective effects. This study is aimed at investigating the cardioprotective and vascular effects of Fumaria indica (F. indica) crude extract on isoproterenol- (ISO-) induced myocardial infarction (MI) in Sprague-Dawley (SD) rats. Rats treated with isoproterenol (85 mg/kg, s.c), administered. Twice at an interval of 24 h showed a significant ST-segment elevation in ECG, edema, and necrosis in histopathology and also in troponin I (cTnI), creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST). Pretreatment with F. indica (10, 30, and 100 mg/kg, p.o) for 21 days significantly reversed the effects of isoproterenol-induced ischemic changes in the ECG, levels of cTnI, CPK, LDH, and AST, and histopathological changes. In isolated rat atrial strips, F. indica induced negative chronotropic and inotropic effects which were not affected by pretreatment with atropine, excluding role of cardiac muscarinic receptors. Cumulative addition of the extract induced a vasorelaxant effect on phenylephrine-evoked contractions in isolated rat aortic rings, which remained unchanged when challenged with L-NAME, excluding role of endothelial NO. However, extract of F. indica concentration dependently reversed contractions evoked with high K+, indicating calcium entry blocking effect. In conclusion, the F. indica extract is a cardioprotective remedy that ameliorates the isoproterenol-induced cardiotoxic effects and reverses cardiac ischemia, and the calcium antagonistic effect might be of useful in the treatment of MI.

Fluorometric quantification of alkaloids in the homeopathic mother tinctures of Vinca minor L. and Fumaria officinalis L.

To assess the toxic potential of the alkaloids, a quantification method is necessary. An ion pair extraction method was used for quantitative fluorometric determination of vincamine, protopine and all contained alkaloids in the mother tinctures of Vinca minor and Fumaria officinalis. The non-fluorescent alkaloids were transformed into an ion pair with sodium-9,10-dimethoxy-anthracene-sulfonate and then fluorometrically determined and quantified in this study. The applicable ion pair was extracted in a suitable organic solvent, where dichloromethane has proven to be beneficial. Conditions for the ion pairing and fluorometric quantification are given. The recovery rate was used to investigate the quality of determinability and the influence of the mother tincture matrix. The method was applied to determine the concentration of protopine in the range 0.1 - 15 µg/ml and of vincamine in the range of 0.5 - 20 µg/ml. The limit of detection was < 0.3 µg/ml, and the limit of quantification < 0.9 µg/ml for both alkaloids.

Shahatra (F.parviflora Lam)- a comprehensive review of its ethnopharmacology, phytochemistry and pharmacology.

ETHNOPHARMACOLOGICAL RELEVANCE: F.parviflora Lam. is a plant widely used in traditional medicine systems like Unani, Ayurveda, and folk medicines in Iraq and Turkey. It is known as Shahatraj in Arabic, which is derived from Shahatra and called Shajaratuddam. In the ancient Unani system, it is called Shajaratuddam. The term derived from Sajarat means tree, and Dam means blood since it has a potent blood purifier property. AIM OF THE STUDY: This review focused on comprehensive, updated information on the F.parviflora Lam. about the traditional uses, phytochemical and pharmacology and provided insights into potential opportunities for future research. MATERIALS AND METHODS: The classical literature of Shahatra for its temperament (Mizaj), medicinal properties and traditional therapeutic uses were gathered from nearly 15 classical Unani books, eight local and foreign books on ethnomedicines and ethnobotany in English. The information of pharmacognosy, phytochemical and pharmacological activities of F.parviflora Lam was collected by browsing the Internet (PubMed, ScienceDirect, Wiley online library, Google Scholar, ResearchGate). The relevant primary sources were probed, analysed, and included in this review. The keywords used to browse were F.parviflora Lam, shahatra, pitpapda, and fine fumitory. Relevant Sources were gathered up to April 2021, and the chemical structures were drawn using Chemsketch software. The species name was checked with http://www.theplantlist.org ("F.parviflora Lam. - The Plant List," n.d.). The materials published in both Urdu and English were included in the review. RESULTS: F.parviflora Lam was found to possess an excess of bioactive compounds and broad pharmacological properties, including antimicrobial activity, antioxidant activity, antiprotozoal activity, anthelmintic activity, antidiarrheal, antispasmodic and bronchodilator activities, antidiabetic activity, hepatoprotective activity, anticancer activity (cytotoxicity)of nanoparticle, antipruritic activity, dermatological effect, reproductive effect, anti-inflammatory and anti-nociceptive activity. CONCLUSION: In this review, the botany, traditional uses, phytochemistry and pharmacology of F.parviflora were reviewed. It showed a broad scope of application, and its benefits had been extended far beyond the initial conventional uses of its parts. It consists of numerous chemical constituents and reported various pharmacological activities such as antimicrobial activity, antioxidant activity, antidiabetic activity, hepatoprotective activity, anticancer activity etc. Though it is widely studied using several in-vitro and in-vivo models and tested clinically for skin diseases, several gaps and research priorities have been identified that need to be addressed in the future, such as active ingredients and their mechanism of action applications in immunomodulation and hepatic diseases.

Production of isoquinoline alkaloids from the in vitro conserved Fumaria parviflora and their in vitro wound healing activity.

Fumaria parviflora Lam. is a rare herbaceous annual plant, with a well-known richness of isoquinoline alkaloids. It is threaten due to expansion on construction in the Mediterranean coastal region. We established callus culture protocol aiming at in vitro conservation of this plant. Murashige and Skoog medium fortified with a combination of 0.5 mg/l 1-naphthaleneacetic acid (NAA) and 1 mg/l 6-benzylaminopurine (BAP) showed optimal callus initiation. UPLC-MS/MS profiling revealed that calli induced on the tested media were able to produce isoquinoline alkaloids. Eight alkaloids were isolated from aerial parts of the cultivated plant and their cytotoxicity against Human skin fibroblast (HF) and wound healing activity using in vitro scratch assay were determined. Structural similarity between the isolated alkaloids enabled structure activity relationship (SAR) study. Sanguinarine displayed the potent activity compared to the other alkaloids. Iminium ion and methylenedioxy potentiated the activity.

Berberis lyceum and Fumaria indica: in vitro cytotoxicity, antioxidant activity, and in silico screening of their selected phytochemicals as novel hepatitis C virus nonstructural protein 5A inhibitors.

Berberis lyceum and Fumaria indica are two Pakistani indigenous herbal medicines used to treat liver infections, including hepatitis C virus (HCV). This study aimed to evaluate the cytotoxicity, and antioxidant activity of these plant extracts and computationally screen their selected phytoconstituents as HCV NS5A inhibitors. The viability of HepG2 cells was assessed 24 h and 48 h post-treatment using colorimetric and dye exclusion methods. Antioxidant properties were examined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH), reducing power, and total antioxidant capacity assays. Seventeen known phytochemicals identified from each plant were docked into the active binding site of HCV NS5A protein. The top hit ligands were analyzed for their druglikeness properties and the indices of absorption, distribution, metabolism, elimination, and toxicity (ADMET). The results showed that both plant extracts were non-toxic (CC50 > 200 µg/ml). The IC50 values of DPPH-radical scavenging activity were 51.02 ± 0.94 and 62.91 ± 1.85 µg/ml for B. lyceum and F. indica, respectively. They also exhibited reducing power and total antioxidant capacity.The phytochemicals were identified as potent HCV NS5A inhibitors with good druglikeness and ADMET properties. Six of the docked phytochemicals exhibited higher binding scores (-17.9 to -19.2 kcal/mol) with HCV NS5A protein than the standard drug, daclatasvir (-17.2 kcal/mol). Molecular dynamics (MD) simulation confirmed the stability of two compounds, berbamine and paprafumine at 100 ns with active site of HCV NS5A protein. The identified compounds through molecular docking and MD simulation could have potential as HCV NS5A inhibitor after further validation.

Determinism and variability of the morphogenesis pathways.

Along with a strict determinism of early embryogenesis in most living organisms, some of them exhibit variability of cell fates and developmental pathways. Here we discuss the phenomena of determinism and variability of developmental pathways, defining its dependence upon cell potency, cell sensitivity to the external signals and cell signaling. We propose a set of conjectures on the phenomenon of variability of developmental pathways, and denote a difference between a normal (local) variability, leading to an invariant final structure (e.g., embryo shape), and fundamental one, which is a switching between different developmental pathways, leading to different possible structures. For illustrating our conjectures, we analyzed early developmental stages of plant embryos with different levels of variability of morphogenesis pathways, and provide a set of computational experiments by Morphogenesis Software.

Cytotoxicity and apoptosis induction by Fumaria officinalis extracts in leukemia and multiple myeloma cell lines.

ETHNOPHARMACOLOGICAL RELEVANCE: Fumaria officinalis (Fumariaceae) is recorded in the Kurdish ethnobotany for various health problems. AIM OF THE STUDY: In this study, the cytotoxic activity of F. officinalis extracts on two leukemia and nine multiple myeloma (MM) cell lines was investigated. MATERIALS AND METHODS: The cytotoxic and ferroptotic activity were examined by resazurin reduction assay. Flow cytometry, immunoblotting assay and fluorescence microscopy were used to measure cell cycle distribution, apoptosis, induction of reactive oxygen species (ROS), loss integrity of mitochondrial membrane potential (MMP) and autophagy. LC-ESI/MS was used to identify chemical constituents present in F. officinalis. RESULTS: Chloroform (CF) and ethyl acetate (EF) fractions showed drastic cytotoxic effect on CCRF-CEM and CEM/ADR 5000 cells. NCI-H929 cell line exhibited higher sensitivity against CF, while EF demonstrated its higher cytotoxicity on OPM-2 cells with IC50 value 14.80 ± 1.70 and 28.13 ± 1.38 µg/mL respectively. Flow cytometric and morphological studies confirmed that CF and EF induced apoptosis in NCI-H929 cells by loss of MMP, generation of ROS and obvious morphological variations. In DNA histograms, up to 50% of the cells were accumulated by CF and 44% by EF in the sub-G0/G1 phase following 72 h treatment. EF induced autophagic cell death, while CF stimulated iron-dependent cell death. Moreover, two isoquinoline alkaloids and four flavonoids were identified in the active fractions. CONCLUSION: To our knowledge, this is the first report demonstrating the cytotoxicity of F. officinalis extracts in MM cell lines. CF and EF fractions inhibited MM cell proliferation through various modes of actions.

Fumaria parviflora regulates oxidative stress and apoptosis gene expression in the rat model of varicocele induction.

Varicocele is one of the leading causes of male infertility in which oxidative stress induces DNA damages in spermatozoa of patients with varicocele. Recent studies indicated that the treatment with antioxidant agents has protective effects against the formation of reactive oxygen species (ROS). Our research aimed to evaluate the impact of Fumaria Parviflora (FP) on the varicocele-induced testicular injury. For this purpose, 32 adult male Wistar rats (n = 8 per group) were randomly assigned to four groups as follows: sham group, varicocele group, varicocele treatment group and the control treatment group. The experimental groups daily received FP (250 mg/kg) for 8 weeks. The induction of varicocele was conducted by partial occlusion on the left renal vein. The diameter of seminiferous tubules, Johnsen's score and the epithelium thickness improved in the treated-varicocele group as compared to the varicocele group. FP extract could increase the biochemical parameters including superoxide dismutase and glutathione peroxidase, and also decrease malondialdehyde level in the varicocele group. Furthermore, varicocele markedly increased both mRNA and intensity of Bax, while treatment with FP could alleviate them. We concluded that FP could alleviate varicocele, possibly by lowering oxidative stress and testicular damage.

Diverse alkaloids and biological activities of Fumaria (Papaveraceae): An ethnomedicinal group.

Fumaria species, commonly known as fumitory or earth smoke, are considered weeds in many regions. However, several Fumaria species have long been used in folk medicine, such as F. capreolata L., F. densiflora DC., F. indica (Hausskn.) Pugsley, F. officinalis L., F. parviflora Lam., and F. vaillantii Loisel. as well. The ethnobotany, phytochemistry, and pharmacology of 24 Fumaria species have been investigated. Phytochemical studies on Fumaria species revealed the presence of numerous alkaloids, flavonoids, saponins, and terpenoids. Phthalideisoquinolines (PTIs), protoberberines, and spirobenzylisoquinolines (SBIs) are the major alkaloids in the genus Fumaria. The plants biosynthesize a diverse group of biologically active isoquinoline alkaloids, and these may help to explain the use of various Fumaria species in folk medicine. Pharmacological studies revealed a broad spectrum of bioactivities such as hepatoprotective, anti-inflammatory, antimicrobial, antioxidant, and antitumor activities. We found 159 articles published from 1969-2019 by searching the keyword "Fumaria" using databases such as SciFinder, Google Scholar, and PubMed. Based on our reading of these papers, Fumaria species appear to be a source of bioactive isoquinoline alkaloids and ethnomedicines. The lack of studies on pharmacological mechanisms, pharmacokinetics, clinical efficacy, quality control, and toxicology are discussed in this review. There is great potential for broader medicinal applications of this genus.

Intestinal anti-inflammatory activity of the total alkaloid fraction from Fumaria capreolata in the DSS model of colitis in mice.

Fumaria genus has been traditionally used for managing inflammatory and gastrointestinal disorders. The study evaluates the immunomodulatory potential of the total alkaloid fraction from Fumaria capreolata L. (AFC) in primary macrophages and the intestinal anti-inflammatory effect in a dextran sodium sulphate-induced colitis in mice. AFC inhibited LPS-stimulated bone marrow-derived macrophages gene expression program dose-dependently. In vivo, AFC markedly reduced macroscopic and microscopic signs of intestinal inflammation. Besides, it restored the colonic expression of pro-inflammatory and anti-inflammatory mediators, as well as enhanced the expression of intestinal barrier markers. These results demonstrate the potential of AFC extract as a therapeutic tool for the management of inflammatory bowel disease.

Effect of dry medicinal plants (wormwood, chamomile, fumitory and mallow) on in vitro ruminal antioxidant capacity and fermentation patterns of sheep.

The objective of this study was to determine the effect of dry medicinal plants (wormwood, chamomile, fumitory and mallow) and dietary substrates containing a mix of the plants on the end products of in vitro ruminal and intestinal fermentation, rumen protozoan population and ruminal antioxidant capacity of sheep. The experiment consisted of fermentations with the four plants used individually as the sole substrate and fermentation of a mix of medicinal plants (Plants): meadow hay:barley grain (MH:B), 700/300 w/w and Plants:MH:B, 100/600/300 w/w/w. The experiment was conducted using the in vitro gas production technique (IVGPT) with 35 ml of buffered inocula and approximately 250 mg (DM basis) of substrate incubated for 24 hr at 39°C in anaerobic conditions. Quantitative analyses of the bioactive compounds by ultra-high-resolution mass spectrometry in Plants identified three main groups: flavonoids (22 mg/g DM), phenolic acids (15 mg/g DM) and alkaloids (3 mg/g DM). The total antioxidant capacity (TAC) of the plant extracts and rumen fluid was analysed using a ferric reducing antioxidant power assay. The values of total and individual short-chain fatty acids, acetate:propionate ratio, pH and total gas production were significantly affected by the single plant substrates and inocula (p < .001). Apart from these parameters, the values of ammonia N, methane production and total gas produced were decreased in Plants:MH:B in comparison with MH:B (p < .001). A positive correlation was recorded between total polyphenols content and TAC of plant extracts (R2  = .778, p < .001). The counts of the total ciliate protozoan population in rumen fluid after 24 hr of fermentation were not significantly different (p > .05). Results suggest that the dietary substrate containing the medicinal plant mix possessed strong ruminal antioxidant capacity, had the potential to reduce methane emission and ammonia concentration and caused desirable changes in the gastrointestinal ecosystem.

Chemical constituents of Fumaria densiflora and the effects of some isolated spirobenzylisoquinoline alkaloids on murine isolated ileum and perfused heart.

Twenty-two alkaloids, were isolated from Fumaria densiflora. Two of these alkaloids, N-methyl-5-hydroxystylopine chloride and fumaricine N-oxide, were isolated for the first time from natural sources. Parfumine and fumaritine, in concentrations ranging from 3 × 10-7 to 9 × 10-4 M, caused concentration-dependent relaxation of ileum longitudinal segment. Also, parfumine and fumaritine in concentrations ranging from 3 × 10-4 to 9 × 10-2 M, caused concentration - dependent decrease in heart rate of the isolated perfused heart. A concentration of parfumine of 3 × 10-2 M increased but a higher concentration (9 × 10-2 M) decreased the amplitude of contraction of the isolated perfused heart. On the other hand, fumaritine, in concentrations ranging from 3 × 10-4 to 3 × 10-2 M, caused concentration - dependent increase, but a higher concentration (9 × 10-2 M) caused a decrease in the amplitude of contraction of the isolated perfused heart.[Formula: see text].

Topical hydrogel containing Fumaria vaillantii Loisel. extract enhances wound healing in rats.

BACKGROUND: Fumaria species (Fumariacea) has traditionally been used in wound healing in Iranian folk medicine. However, with the discovery of newer agents, its use has faded off into total obscurity. This study explored the wound healing potential of a gel containing 10% Fumaria vaillantii Loisel through topical application of total extract in a model of excisional as well as incisional wound healing in albino Wistar rats. METHODS: Rats were anesthetized, and excisional skin wound was established using a sterilized surgical scissors. The animals were then treated with 10% F.vaillantii topical gel formulation along with the gel base. The treatments were administered once a day after the injury for 21 days. For topical treatment, the hydrogel was formulated and evaluated for chemical and physical characteristics. Histopathological analysis with hematoxylin and eosin (H&E) was used for microscopic examination of the skin tissues on 21-day-old sections of excision wound. To verify collagen formation, hydroxyproline determination was performed 21 days post wound healing. Breaking strength was determined in a 10-day-old incision wound by the uniaxial tensile test. RESULTS: Topical administration of F.vaillantii gel formulation significantly enhanced skin wound closure on the 6th post-wounding day compared to both gel base and the negative control, indicating an accelerated wound healing process, while a significant difference was observed on 10th and 14th post -wound days in F.vaillantii treatment compared to the negative control groups. Gel formulation prepared with a 10% F. vaillantii extract exhibited a response in terms of wound epithelialization, angiogenesis and number of hair follicles at wound area better than the gel base on the 21st post-wound day. Application of gel base produced further advantages by increasing hydroxyproline content and collagen fiber thickness. Our results on incision wound model were supported by histopathological data indicating the role of gel base in the enhancement of breaking strength. CONCLUSION: Traditional use of Fumaria species in the skin diseases was justified in this study by revealing the increase in wound healing activity after hydrogel containing F. vaillantii total extract administration.

Evaluation of anticonvulsant and antiepileptogenic activity of Euphorbia nivulia in PTZ-induced kindling model of epilepsy in mice.

Epilepsy remains a major chronic neurological disorder with significantly higher refractory seizure rate. Based on the folk medicine literature, we explored the anticonvulsant and antiepileptogenic activity of aqueous ethanolic extracts of Fumaria indica, Euphorbia lactea, Euphorbia helioscopia, Neurada procumbens, and Euphorbia nivulia. The acute anticonvulsant activity of the extracts was determined at different concentrations in different groups of Swiss albino mice. Among all the materials tested, the ethanolic extracts of Euphorbia nivulia (eth-EN) alone was found to exhibit concentration-dependent anticonvulsant effects when evaluated against the acute convulsant dose of Pentylenetetrazole (PTZ, 90mg/kg, s.c.). eth-EN extract at 100mg/kg i.p concentration showed maximum protection against the PTZ induced mortality (P<0.05). eth-EN (100mg/kg) treated animals also showed significant reduction in the progression of epileptogenesis (P<0.05) when tested against the PTZ-induced (50mg/kg s.c.) chemical kindling model of epilepsy. The FT-IR spectra of this extract showed both known and unknown spectral peaks from which the presence of the functional groups; i.e. aromatics, diketones, alkenes, carbonyls, carboxylic acids and amide compounds were confirmed. The unknown peaks strongly suggested the presence of novel compounds that may be responsible for its anticonvulsant and antiepileptogenic activity.

Report: Assessment of Fumaria indica, Dicliptera bupleuroides and Curcuma zedoaria for their antimicrobial and hemolytic effects.

The present investigation was undertaken to evaluate the antibacterial, antifungal and hemolytic activities of organic and aqueous fractions of Fumaria indica, Dicliptera bupleuroides and Curcuma zedoaria. The methanolic extracts of the plants were dissolved in the water (distilled) separately and then partitioned with the n-hexane, CHCl3, EtOAc and n-BuOH sequentially. Antibacterial activity was checked against Escherichia coli, Pasturella multocida, Bacillus subtilis and Staphylococcus aureus by the disc diffusion method using streptomycin sulphate, a standard antibiotic, as positive control. Antifungal activity was studied against four fungi i.e. Aspergillus niger, Aspergillus flavus, Ganoderma lucidum and Alternaria alternata by the disc diffusion method using fluconazole, a standard antifungal drug, as positive control. It was revealed that aqueous fraction of F. indica showed very good antibacterial activity against P. multocida with zone of inhibition 26mm and MIC of 98µg/mL. Its CHCl3 and n-BuOH fractions also displayed good results. Its CHCl3 fraction showed good antifungal activity against G. lucidum with zone of inhibition 24mm and MIC of 115µg/mL. Other polar fractions of F. indica showed good activity against somefungal strains. The CHCl3 and EtOAc fractions of D. bupleuroides displayed good antibacterial activity against some bacterial strains. Its EtOAc fraction showed good antifungal activity only against G. lucidum. The CHCl3 fraction of C. zedoaria showed good activity against all studied bacterial strains, while its EtOAc and n-BuOH fractions displayed good results against some bacterial strains. None of the fractions of C. zedoaria displayed antifungal activity against the under test strains. All the studied fractions of three plants showed very less toxicity except n-hexane fraction of D. bupleuroides which showed 79% toxicity.
