从海南特有植物锈毛野桐Mallotus anomalus meer et Chun的地上部分又分得三个新的对映一玫瑰烷(rosane)型三环二萜类成分: 锈毛醇酮, 异锈毛醇酮, 锈毛双醇酮。根据其理化数据和核磁共振NOE及二维谱技术推定了它们的结构。

Besides anticancer maytansinoids (mallotunsine and isomallotunsine), three new ent-rosane type diterpenoids have been additional isolated from the aerial part of Mallotus anomalus Meer et Chun (Euphorbiacea), a special shrub growing in Hainan Island. They are named anomallotusin (I), m.p. 155-156 癈, [a]D 52.6? isoanomallotusin (II) m.p. 213-215 癈, [a]D 101.2? and anomalotusinin (III) m.p. 175-176 癈, [a]D 117.6? resp. Their structures were elucidated on the basis of spectral anal. including Homo- and Hetro-nuclear 2D NMR and long range 12C-1H COSY techniques.
