Chemical investigation of the dichloromethane extract of Cycas wadei, a plant endemic to the Philippines, led to the isolation of d-tocopherol (1), ß-sitosterol (2), ß-sitosteryl fatty acid ester (3), triacylglycerol (4) from the megasporophyll lamina; 2, trilinolein (5), a mixture of linoleic acid and oleic acid, and hydrocarbons from the sarcotesta; 2, chlorophyll a (6), fatty alcohol, and hydrocarbons from the leaflets; a mixture of 2 and stigmasterol (7),squalene (8), and fatty alcohol from the petiole and rachis; 2 and 4 from the endotesta; 3 and 4 from the sclerotesta; and a mixture of 2 and 7, 8 and fatty alcohol from the roots ofCycas wadei. The structures of these compounds were identified by comparison of their NMR data with literature data.
