A new triterpene, 28-hydroxy-3-oxo-30-lupanoic acid (1), and a triterpene found for the first time as a natural product, 3-oxo-lupane-30-al (2), besides three known triterpenes, 29-nor-21α-H-hopane- 3,22-dione (3), 21α-H-hop-22(29)-ene-3β , 30-diol (4), and betulin (5) have been isolated from the n-hexane extract of Salacia chinensis stems.
