Abstract

Three new dammarane triterpenes and semialactic acid were isolated from the stem bark of Rhus javanica. The structures of these triterpenes, named semialactone, isofouquierone peroxide and fouquierone, were elucidated by 2D-NMR analysis (HMQC, ¹H-¹H COSY and HMBC), and the ¹³C-NMR data of semialatic acid is revised.
