Abstract

The monoterpene loliolide (1), a light yellowish-brown oil, was isolated from the ethyl acetate leaf extracts of Pterocarpus indicus by silica gel chromatography. The structure of 1 was deduced by comparison of its 1H- ahd 13C-NMR chemical shifts with those found in the literature for loliolide. Antimicrobial tests on 1 indicated that it has moderate activity against the fungus, Candida albicans, and low activity against the bacteria, Pseudomonas aeruginosa and Escherichia coli, and the fungus, Aspergillus niger. It was found inactive against the bacteria, Staphylococcus aureus and Bacillus subtilis, and the fungus, Trichophyton mentagrophytes.
