title: Abietane diterpenoids from Cephalotaxus lanceolata.
abstract: A new abietane diterpenoid, 12-O-methyl-20-deoxocarnosol-3-one (1), and eight known abietane diterpenoids including 13-abietadien-12-one (2), 5,6-dehydrosugiol (3), sugiol (4), torreyayunnin (5), taxusabietane A (6), hinokiol (7), 3-acetoxyabieta-8,11,13-trien-12-ol (8), and martiusane (9) were obtained from leaves and twigs of Cephalotaxus lanceolata. The structures of isolated compounds (1-9) were determined based on analysis of their spectroscopic data and comparison with those reported in the literature. Compounds 3, 8 and 9 were first isolated from the plants of Cephalotaxus genus.
