Abstract

The aerial parts of Nicandra physaloides plant collected from Kenyatta National Hospital grounds were dried and subjected to acid-base extraction and partitioned to obtain alkaloidal and non-alkaloidal extracts. The  non-alkaloidal extract yielded three compounds; withanicandrin, â-sitosterol and stigmasterol after column chromatography. Withanicandrin exhibited antifungal activity against Saccharomyces cerevisiae and Candida albicans but lacked antibacterial activity.

Key words: Nicandra physaloides, withanicandrin, β-sitosterol, stigmasterol, antifungal activity.
