Antimicrobial terpenoids from Pterocarpus indicus
A mixture of loliolide 1 (> 85%) and paniculatadiol 2 (< 15%) was obtained from the ethyl acetate leaf extract of Pterocarpus indicus by silica gel chromatography, while the air-dried flowers afforded lupeol 3 and phytol esters 4. The structures of 1-4 were determined by NMR spectroscopy. Anti...
