Terpenoids from Tripterigyum hypoglaucum.

Six terpenoids have been isolated from the root bark of Tripterygium hypoglaucum, along with 14 known compounds. The structures of the terpenoids were elucidated as 3,11,14-oxo-abieta-8,12-diene, 3beta-hydroxy-12,14-dimethoxyabieta-8,11,13-triene, 3beta-hydroxy-11alpha-ethoxyurs-12-ene, 3beta-hydroxy-11alpha-methoxyurs-12-ene, 3beta-hydroxy-11alpha-methoxyolean-12-ene-28-oic acid, and 1beta-benzoyl-8alpha-cinnamoyl-4alpha,5alpha- dihydroxydihydroagarofuran.
