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
