JOURNAL OF ETHNOPHARMACOLOGY 2022; 286:114839. [PMID: 34896208 DOI: 10.1016/j.jep.2021.114839] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 10/28/2021] [Accepted: 11/12/2021] [Indexed: 06/14/2023]
Abstract
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.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) with rising prevalence in developing countries, and limited success of current therapies, natural products have immense potential for therapy due to their "disease modifying and side-effect neutralizing" potential. Myrica salicifolia is traditionally used for gastrointestinal diseases and have reported antiinflammatory activities, but its use in IBD has not yet been studied. Therefore, in the present study, the effects of the root extract of M. salicifolia (Ms.Cr) were investigated using the acetic acid-induced UC model in rats. For 6 days, the rats were given either vehicle (10 mL/kg), lower (200 mg/kg), and higher (400 mg/kg) doses of Ms.Cr, or the positive control drug (prednisolone; 2 mg/kg) orally. A single dosage of 5% acetic acid (1.0 mL) was administered intrarectally to rats on day 6 to induce UC. Disease activity index (DAI), histological observations, the biochemical parameters related to oxidative stress, and specific cytokines such as interleukin-6 (IL-6) and the tumor necrosis factor-α (TNF-α) were determined to assess the effect of Ms.Cr. In comparison to the AA-induced colitis rats, Ms.Cr's pretreatment significantly decreased DAI, colonic ulceration, and inflammatory score. Total glutathione levels and catalase activity were considerably recovered in the colitis group treated with Ms.Cr, whereas enhanced lipid peroxidation in colon tissues was significantly decreased. Moreover, Ms.Cr pretreatment also caused inhibition of the activation of IL-6 and TNF-α in the colonic tissues of respective groups. Based on these findings, Ms.Cr might be developed to treat UC in the future.

[PMID: 37303860 PMCID: PMC10251284 DOI: 10.4103/ayu.ayu_16_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 01/13/2023] [Accepted: 02/13/2023] [Indexed: 06/13/2023] Open
Abstract
Background National Institute of Ayurveda, Jaipur, India, had distributed Ayurveda immunity booster kit (AIBK) (prepared at own pharmacy and comprising Chyawanprasha - 300 g, Vyadhi Kshamatva Kwatha - 300 g, and Vyadhi Kshamatva capsule - 30 g) for 15 days among the health-care workers, sanitation workers, and security and police staff engaged in the containment zones for prevention of COVID-19. Aim The aim of present study was to explore the medication that may be effective in prevention of the COVID -19. Hence, this study was done to assess the compliance of these medicines and their effects in the prevention of COVID-19. Methods One thousand seven hundred and fourteen frontline workers were provided with the AIBK for 15 days from April 24, 2020, to June 27, 2020. Data of frontline workers who had participated in AIBK and completed the treatment regimen with 2 weeks of follow-up after treatment with complete available data for safety, palatability, efficacy, and compliance were included in the study. Any adverse event needing hospitalization or medication, drug compliance and palatability, and appearance of the symptoms of COVID-19 or testing positive for COVID-19 were the outcome measures. Results Out of 1714 participants, 1003 participants were found to be eligible for this analysis. The median age of these participants was 39 years (range, 19-70), and males accounted for 90.1% (904 of 1003). A total of 7.5% of participants (75 of 1003) reported having adverse events after taking the study treatment. None of the participants reported any serious adverse effects after the administration of the AIBK. The acceptability of the AIBK was as high as 97.4%. None of the participants reported positive for COVID-19 results or COVID-19 symptoms up to 2 weeks of follow-up after completion of the study treatment. Conclusion The acceptability of AIBK is good and indicates its role in the prevention of COVID-19-like illness, hence further randomized control trials or cohort studies can be done to assess the mechanism of action and efficacy of AIBK as the preventive strategy in COVID-19.

Abstract
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.

Abstract
Abstract
Objectives
The oral rehydration solution is the most efficient method to treat cholera; however, it does not interfere in the action mechanism of the main virulence factor produced by Vibrio cholerae, the cholera toxin (CT), and this disease still stands out as a problem for human health worldwide. This review aimed to describe therapeutic alternatives available in the literature, especially those related to the search for molecules acting upon the physiopathology of cholera.
Key findings
New molecules have offered a protection effect against diarrhoea induced by CT or even by infection from V. cholerae. The receptor regulator cystic fibrosis channel transmembrane (CFTR), monosialoganglioside (GM1), enkephalinase, AMP-activated protein kinase (AMPK), inhibitors of expression of virulence factors and activators of ADP-ribosylarginine hydrolase are the main therapeutic targets studied. Many of these molecules or extracts still present unclear action mechanisms.
Conclusions
Knowing therapeutic alternatives and their molecular mechanisms for the treatment of cholera could guide us to develop a new drug that could be used in combination with the rehydration solution.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2020; 2020:1021258. [PMID: 32104188 PMCID: PMC7040422 DOI: 10.1155/2020/1021258] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/10/2019] [Revised: 12/31/2019] [Accepted: 01/06/2020] [Indexed: 12/14/2022]
Abstract
Asthma, a disease classified as a chronic inflammatory disorder induced by airway inflammation, is triggered by a genetic predisposition or antigen sensitization. Drugs currently used as therapies present disadvantages such as high cost and side effects, which compromise the treatment compliance. Alternatively, traditional medicine has reported the use of natural products as alternative or complementary treatment. The aim of this review was to summarize the knowledge reported in the literature about the use of natural products for asthma treatment. The search strategy included scientific studies published between January 2006 and December 2017, using the keywords "asthma," "treatment," and "natural products." The inclusion criteria were as follows: (i) studies that aimed at elucidating the antiasthmatic activity of natural-based compounds or extracts using laboratory experiments (in vitro and/or in vivo); and (ii) studies that suggested the use of natural products in asthma treatment by elucidation of its chemical composition. Studies that (i) did not report experimental data and (ii) manuscripts in languages other than English were excluded. Based on the findings from the literature search, aspects related to asthma physiopathology, epidemiology, and conventional treatment were discussed. Then, several studies reporting the effectiveness of natural products in the asthma treatment were presented, highlighting plants as the main source. Moreover, natural products from animals and microorganisms were also discussed and their high potential in the antiasthmatic therapy was emphasized. This review highlighted the importance of natural products as an alternative and/or complementary treatment source for asthma treatment, since they present reduced side effects and comparable effectiveness as the drugs currently used on treatment protocols.

Abstract
Natural products with antispasmodic activity have been used in traditional medicine to alleviate different illnesses since the remote past. We searched the literature and compiled the antispasmodic activity of 248 natural compounds isolated from terrestrial plants. In this review, we summarized all the natural products reported with antispasmodic activity until the end of 2017. We also provided chemical information about their extraction as well as the model used to test their activities. Results showed that members of the Lamiaceae and Asteraceae families had the highest number of isolated compounds with antispasmodic activity. Moreover, monoterpenoids, flavonoids, triterpenes, and alkaloids were the chemical groups with the highest number of antispasmodic compounds. Lastly, a structural comparison of natural versus synthetic compounds was discussed.

Abstract
Achyranthes aspera L. is traditionally used to relieve constipation, diarrhea, and asthma. Its crude extract (Aa.Cr) was evaluated through in vivo and ex vivo experiments to rationalize these medicinal uses of A. aspera and to provide their scientific basis. Aa.Cr, at 3 and 10 mg/kg, increased fecal output, similar to castor oil, whereas at 30, 100, 300, and 700 mg/kg, it protected against castor oil-induced diarrhea in mice when administered orally. Aa.Cr caused spasmogenic effect on rabbit jejunum and guinea pig ileum preparations, which was partially inhibited by atropine while completely blocked by cyproheptadine preincubation. Aa.Cr also relaxed high K+ (80 mM)-induced contraction in rabbit jejunum. Aa.Cr inhibited CCh (100 μg/kg)-induced bronchospasm in rats, similar to aminophylline. Like dicyclomine, Aa.Cr relaxed high K+ and CCh (1 μM)-induced contractions in guinea pig trachea and caused rightwards parallel shift of CCh concentration-response curves at the lower concentrations followed by non-parallel shift at the higher concentrations. On activity-directed fractionation, spasmogenic and spasmolytic activities of Aa.Cr were concentrated in aqueous and organic fraction, respectively. This study suggests the presence of dose-specific laxative and antidiarrheal effects in A. aspera, possibly mediated through cyproheptadine-sensitive receptors and dual cholinergic and calcium channel blockade, respectively. The latter combination is also a suggested mechanism underlying its bronchodilator effect. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
Currently, >35 Saudi Arabian medicinal plants are traditionally used for various liver disorders without a scientific rationale. This is the first experimental evaluation of the anti-hepatitis B virus (HBV) potential of the total ethanolic and sequential organic extracts of 60 candidate medicinal plants. The extracts were tested for toxicity on HepG2.2.15 cells and cytotoxicity concentration (CC50) values were determined. The extracts were further investigated on HepG2.2.15 cells for anti-HBV activities by analyzing the inhibition of HBsAg and HBeAg production in the culture supernatants, and their half maximal inhibitory concentration (IC50) and therapeutic index (TI) values were determined. Of the screened plants, Guiera senegalensis (dichloromethane extract, IC50=10.65), Pulicaria crispa (ethyl acetate extract, IC50=14.45), Coccinea grandis (total ethanol extract, IC50=31.57), Fumaria parviflora (hexane extract, IC50=35.44), Capparis decidua (aqueous extract, IC50=66.82), Corallocarpus epigeus (total ethanol extract, IC50=71.9), Indigofera caerulea (methanol extract, IC50=73.21), Abutilon figarianum (dichloromethane extract, IC50=99.76) and Acacia oerfota (total ethanol extract, IC50=101.46) demonstrated novel anti-HBV activities in a time- and dose-dependent manner. Further qualitative phytochemical analysis of the active extracts revealed the presence of alkaloids, tannins, flavonoids and saponins, which are attributed to antiviral efficacies. In conclusion, P. crispa, G. senegalensis and F. parviflora had the most promising anti-HBV potentials, including those of C. decidua, C. epigeus, A. figarianum, A. oerfota and I. caerulea with marked activities. However, a detailed phytochemical study of these extracts is essential to isolate the active principle(s) responsible for their novel anti-HBV potential.

Evaluation of Polyphenolic Content, Antioxidant and Diuretic Activities of Six Fumaria Species. Molecules 2017; 22:molecules22040639. [PMID: 28420145 PMCID: PMC6154649 DOI: 10.3390/molecules22040639] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2017] [Revised: 04/07/2017] [Accepted: 04/08/2017] [Indexed: 11/17/2022] Open
Abstract
Romanian traditional medicine describes the use of aerial parts of Fumaria species to treat hepatobiliary diseases as well as diuretic agents. The present study aims to investigate the chemical composition, antioxidant properties, and diuretic effects of several Fumaria species. LC/MS analysis revealed that Fumaria species contain phenolic acids and high amounts of flavonoids with rutin and isoquercitrin as main compounds. Concerning antioxidant capacity, the most significant results were obtained for F. capreolata and F. vailantii. Both species showed a good correlation between the antioxidant capacity and a high amount of flavonoids. Furthermore, the extracts of F. officinalis and F. schleicheri produced a strong increase in urinary volumetric excretion of saline-loaded rats, 24 h after the oral administration of a single dose of 250 mg/kg bw. Moreover, both extracts of F. officinalis and F. schleicheri increased the urinary excretion of Na⁺ and K⁺. Results from the present study offer a new perspective concerning the chemical composition and bioactivities of traditionally used fumitory species.

Abstract
Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents. Since ancient time, Ayurveda is the main system of healing in South East Asian countries. Indian literature from ayurvedic texts and other books claim the potency of several plants in the treatment of diarrhea. As the global prospective of ayurvedic medicine is increasing, interest regarding the scientific basis of their action is parallely increasing. Researchers are doing experiments to establish the relation between the claimed action and observed pharmacological activities. In the present article, an attempt was made to compile the scientific basis of medicinal plants used to cure diarrhea in Ayurveda. Literature was collected via electronic search (PubMed, ScienceDirect, Medline, and Google Scholar) from published articles that reports antidiarrheal activity of plants that were mentioned in Ayurveda classics. A total of 109 plant species belonging to 58 families were reported for their antidiarrheal activity. Several Indian medicinal plants have demonstrated promising antidiarrheal effects, but the studies on the antidiarrheal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area.

Effect of Imperatorin on the Spontaneous Motor Activity of Rat Isolated Jejunum Strips. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:614849.

Abstract
Imperatorin, a psoralen-type furanocoumarin, is a potent myorelaxant agent acting as a calcium antagonist on vascular smooth muscle. Its effects on other types of smooth muscle remain unknown. Therefore, the aim of this study was to investigate the hypothesized myorelaxant effect of imperatorin on gut motor activity and, possibly, to define the underlying mechanism of action. Imperatorin was made available for pharmacological studies from the fruits of the widely available Angelica officinalis through the application of high-performance countercurrent chromatography (HPCCC). Imperatorin generated reversible relaxation of jejunum strips dose-dependently (1–100 μM). At 25 and 50 μM, imperatorin caused relaxation comparable to the strength of the reaction induced by isoproterenol (Isop) at 0.1 μM. The observed response resulted neither from the activation of soluble guanylate cyclase, nor from β-adrenoreceptor involvement, nor from Ca2+-activated potassium channels. Imperatorin relaxed intestine strips precontracted with high potassium concentration, attenuated the force and duration of K+-induced contractions, and modulated the response of jejunum strips to acetylcholine. The results suggest that imperatorin probably interacts with various Ca2+ influx pathways in intestine smooth muscle. The types of some calcium channels involved in the activity of imperatorin will be examined in a subsequent study.

Abstract
This review summarizes literature related to medicinal plants reputed in traditional medical systems for treatment of asthma and coughs. The plants that are pharmacologically investigated for their effectiveness in such conditions, along with respective experimental protocol details, are also discussed. Some of plant origin compounds, which are considered useful as antitussive and antiasthmatic agents, are described as well. Chrysoeriol, a constituent of Aspalathus linearis (Fabaceae) was observed to be selective for relaxant effect in airways (through K+ channel activation), compared with other smooth muscles. We reported that Hypericum perforatum (Hyperieaceae), Andropogon muricatus (Poaceae), Juniper excelsa (Coniferae) and Nepeta cataria (Lamiaceae) exhibit bronchodilatory action, mediated through combination of Ca++ antagonist and phospohodiesrase inhibitory mechanisms, which scientifically explains their medicinal use in asthma. Hyocyamus niger (Solanaceae), Artemisia vulgaris (Compositae), Fumaria parviflora (Fumariaceae) and Terminalia bellerica (Combretaceae) caused bronchodilation via dual blockade of muscarinic receptors and Ca++ influx. Acorus calamus (Araceae), Carum roxburghianum (Apiaceae), Lens culinaris (Fabaceae) and Lepidium sativum (Cruciferae) mediate bronchodilatation through multiple pathways: anticholinergic and inhibition of Ca++ channels and PDE enzyme(s). In conclusion, this review presents an analysis of different novel combinations of pharmacological activities in medicinal plants with side effect-neutralizing/synergistic potential, setting new trends in the therapeutic options for hyperactive respiratory disorders such as asthma and cough.

JOURNAL OF ETHNOPHARMACOLOGY 2015; 160:61-8. [PMID: 25433250 DOI: 10.1016/j.jep.2014.11.030] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2014] [Revised: 10/08/2014] [Accepted: 11/19/2014] [Indexed: 05/23/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Linum usitatissimum, commonly known as Flaxseed has traditionally been used for the management of diarrhea and gastrointestinal infections. This study was planned to assess pharmacological basis for the medicinal use of Flaxseed in infectious and non-infectious diarrhea. MATERIALS AND METHODS The crude aqueous-methanolic extract of Flaxseed was studied using the in vivo castor oil-induced diarrhea, gut motility and enteropooling assays. Mechanistic basis was further elucidated by testing the inhibitory effect on spontaneously contracting isolated rabbit jejunum preparations, suspended in a 10ml tissue bath containing Tyrode׳ solution, maintained at 37°C and aerated with carbogen. Antibacterial efficacy of the Flaxseed extract was tested against different enteric and non-enteric pathogenic bacteria using in vitro antibacterial assays. RESULTS Flaxseed extract reduced the diarrheal score in mice, by 39%, 63.90% and 68.34% at the respective doses of 100, 300 and 500mg/kg. Intestinal secretions were reduced by 24.12%, 28.09% and 38.80%, whereas the intestinal motility was reduced by 31.66%, 46.98% and 56.20% at respective doses of 100, 300 and 500mg/kg. When tested on isolated rabbit jejunum preparations, Flaxseed extract produced a dose-dependent inhibition of both spontaneous and high K(+) (80mM)-induced contractions, and shifted the concentration-response curves of Ca(++) to the right with suppression of the maximum response, similar to that caused by verapamil. Flaxseed extract was found to possess bactericidal activity at the tested concentrations of 12.5mg/ml, against vancomycin-resistant Enterococcus faecalis (100%), Escherichia coli K1 (88.88%), methicillin-resistant Staphylococcus aureus (98.76%), Bacillus cereus (92.64%), Pseudomonas aeruginosa (76.83%) and Salmonella typhi (26.91±3.35%). The concentration of 10mg/ml showed bactericidal effects against all the aforementioned pathogens except Escherichia coli K1, whereas for Pseudomonas aeruginosa and Salmonella typhi, it was bacteriostatic at this concentration. CONCLUSIONS Our results indicate that Linum usitatissimum (Flaxseed) extract exhibits antidiarrheal and antispasmodic activities by virtue of its antimotility and antisecretory effects which are mediated possibly through inhibition of Ca(++) channels, though additional mechanism(s) cannot be ruled out. Flaxseed extract proved effective against both enteric and non-enteric pathogens causing diarrhea, thus ensuring wide coverage and rationalizing its medicinal use in both the infectious and non-infectious diarrhea.

Abstract
BACKGROUND Fumaria parviflora Lam. (Fumaraceae) is widely used in traditional as well as folkloric system of medicine from ancient. It is commonly known as 'Pitpapra' or 'Shahtrah' in Indian traditional system of medicine and used for treating numerous ailments like diarrhea, fever, influenza, blood purifier and other complications. The object of the present study was to evaluate the Antileishmanial, antibacterial, antifungal and cytotoxic potential of isolated compound. METHODS Methanolic extract of whole plant of Fumaria parviflora was dried under reduced pressure to obtain a dark brown residue which was adsorbed on silica gel column grade (60-120 mesh) to obtain a slurry and chromatographed over silica gel loaded column in petroleum ether-chloroform (3:1, 1:1 and 1:3 v/v). The in vitro antileishmanial evaluation of isolated compound against Leishmania donovani promastigotes was investigated by growth kinetics assay, reversibility assay, analysis of cellular morphology, adverse toxicity and determination of 50% growth inhibitory concentration (GI50). Disc diffusion and broth micro dilution methods were used to study the antibacterial (Gram + Staphylococcus epidermidis and Bacillus subtilis; Gram - Escherichia coli and Salmonella typhimurium) and antifungal (Candida albicans and Aspergillus niger) potential in vitro. RESULTS Structure elucidation by spectral data analysis revealed a novel compound, n-octacosan-7β-ol (OC), yield (0.471%), having significant antimicrobial activity against Leishmania donovani promastigotes, Staphylococcus epidermidis, Escherichia coli, Candida albicans and Aspergillus niger in vitro with GI50 = 5.35, MIC 250, MIC 250 and MFC 500 and MIC 250 μg ml(-1) respectively. The isolated compound did not show adverse effect against mammalian macrophages. CONCLUSIONS The available evidence of compound suggested that it may be used as antimicrobial agent in future and may provide new platform for drug discovery programmes for leishmaniasis.
