Abstract


Three non-alkaloidal constituents: harringtonolide (nor-diterpene lactone), epicatechin and epigallocatechin have been isolated from Cephalotaxus mannii, collected in Lam Dong province, Vietnam in the frame work of the Tay Nguyen program III (TN III-15). Their structures were elucidated by the spectroscopic methods as the IR, ESI-MS, HR ESI-MS and NMR (1D, 2D) spectroscopy and comparison with published data. This is the first report of these compounds from Cephalotaxus mannii.

Keywords. Cephalotaxus mannii, harringtonolide, epicatechin, epigallocatechin.
