Isolation, Characterization and Antimicrobial Evaluation of Seed Extract of <i>Jatropha gossypifolia</i>

Abstract

Powdered seed of J. gossypifolia was macerated using methanol as extracting solvent. The seed extract of Jatropha gossypifolia was subjected to phytochemical and antimicrobial investigation using standard screening procedures. The phytochemical studies revealed the presence of some secondary metabolites such as alkaloids, saponins, tannins. There was no activity against the bacteria (Gram positive and negative organisms at 2.5-100mg/ml). The seed extract showed significant antifungal activity. The spectroscopic analysis (1D and 2DNMR) of the colourless oil gave 9-acetoxynerolidol.
