Chemical constituents of Cycas edentata
Chemical investigation of the dichloromethane extracts of Cycas edentata led to the isolation of 9αH-isopimara-7,15-diene (1), β-sitosteryl fatty acid ester (2), and a mixture of β-sitosterol (3a) and stigmasterol (3b) from the bark; and 2 and a mixture of 3a and 3b from the sclerotesta. The structu...
