Terpenoids from Chloranthus multistachys

Two new diterpenoids, ent-17-hydroxyl-16 beta-methoxyl-kauran-3-one (1) and ent-17-acetoxyl-16 beta-methoxyl-kauran-3-one (2), along with nine known compounds (3-12), ent-17-hydroxyl-kaur-15-en-3-one (3), ent-3 beta-acetoxyl-kaur-15-en-16 beta, 17-diol (4), ent-kauran-3 beta, 16 beta, 17-triol (5), ent-3 beta-acetoxyl-kauran-16 beta, 17-diol (6), ent-kauran-16 beta, 17-diol (7), abbeokutone (8), ent-17 alpha-acetyl-16 beta-hydroxyl- kauran-3-one (9), shizukaol F (10), cycloshizukaol A (11) and curcolonol (12), were isolated from Chloranthus multistachys (Chloranthaceae). Their structures were elucidated by spectroscopic spectra.
