Abstract

Chemical investigation of the dichlroromethane extracts of Cycas nitida afforded triacylglycerol(1),squalene (2), fatty acid methyl esters (3), a mixture of β-sitosterol (4) and stigmasterol (5), and fatty alcohol (6) from the bark; 1, 4, and a mixture of 3 and β-sitosteryl fatty acid ester (7) from the sarcotesta; 2 and chlorophyll a (8) from the leaflets; 2, 4, and 5 from the roots;1, anda mixture of 4 and 5 from the endotesta; a mixture of 4 and 5 from the petiole and rachis;1 from the megasporophyll lamina; and 2 from the sclerotesta.
