Abstract

Five new diterpenoids, 11-hydroxyabieta-8,11,13-trien-7-one (1), 11,12,14-trihydroxyabieta-8,11,13-trien-7-one (2), 6β,7α-diacetoxyroyleanone (3), 7β-hydroxymanoyl oxide (4), and 9α-hydroxyisopimara-8(14),15-dien-7-one (5) were obtained from the bark of Taiwania cryptomerioides. The structures of the new compounds 1—5 were elucidated on the basis of spectral analysis and chemical evidence.
