Abstract
The leaves of Ficus pumila afforded a new neohopane (1) by silica gel chromatography. The structure of 1 was elucidated by 1D and 2D NMR and IR spectroscopy and mass spectrometry. It showed antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Bacillus sub-tilis and Candida albicans with an average antimicrobial index of 0.5, 0.3, 0.3 and 0.7, respectively, at a concentration of 30 μg.
