Abstract

Chemical investigation of the dichlroromethane extracts of Cycas flabellata, a plant endemic to the Philippines afforded 9αH-isopimara-7,15-diene (1), squalene (2), β-sitosterol (3), methyl fatty acid ester (4), and triacylglycerols (5) from the roots; 3 and 4 from the endotesta; 3 from the sclerotesta; and 2, a mixture of 3 and stigmasterol (6) in a 1:1 ratio, and β-sitosterone (7) from the petiole and rachis. The structures of 1-7 were identified by comparison of their NMR data with literature data.
