从香柏树（Excoecaria agallocha）中分离到一种新的异吡马烷型二萜，3 α，11 β -二羟基- ent -异吡马烷-8(14)，15-二烯-2-one(1)和一种新的天然atisane型二萜，16 β -羟基- ent -atisan-3-one(2)，以及三种已知化合物ribenone (3), ent -labda-8(17),13 E -diene-3 β,15-diol(4)和ent -3 β -hydroxybeyer-15-ene-2,12-dione(5)。它们的结构由光谱数据和x射线晶体学证据确定。
From the woods of Excoecaria agallocha , a new isopimarane-type diterpene, 3 alpha,11 beta-dihydroxy- ent -isopimara-8(14),15-dien-2-one (1) and a new natural atisane-type diterpene, 16 beta-hydroxy- ent -atisan-3-one (2) were isolated together with three known compounds, ribenone (3), ent -labda-8(17),13 E -diene-3 beta,15-diol (4), and ent -3 beta-hydroxybeyer-15-ene-2,12-dione (5). Their structures were determined by spectral data and x-ray crystallography evidence.
