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.
