Abstract: Two new triterpenes, 3-oxo-29-hydroxy-urs-12-en-27 , 28-dioic acid (Metatrichosin A, 1 ) and 3-oxo-21β-hydroxy-urs-12-en-27 , 28-dioic acid (Metatrichosin B, 2) , were isolated from the barks of Metadina trichotoma (Zoll. et. Mor. ) Bakn. Their structures were mainly determined byMS, 1D and 2D NMR spectroscopic methods.
Key words: Metadina trichotoma
摘要： 从黄棉木( Metadina trichotoma (Zoll . et . Mor .) Bakn .) 树皮中分离得到2 个新的三萜类化合物: 3-oxo-29-hydroxy-urs-12- en-27 , 28-dioic acid ( 黄棉木素A, 1) 和3-oxo-21β-hydroxy-urs-12- en-27 , 28-dioic acid ( 黄棉木素B, 2 )。其结构主要通过MS, 1D 以及2D NMR 等波谱方法鉴定。
