    The tropical family Guttiferae is well known to be rich source of isoprenylated xanthones and biflavonoids as mayor compound and triterpenoid as minor with variety of biologically active such antioxidant, antimalaria, anticancer, and antibacterial activity. Garcinia cornea known as manggu lauweung, as part of a phytochemical study in Guttiferae we have previously reported the presence chemical constituent of a triterpenoid 3-oxo friedelin (1) and now describe the isolation and structure elucidation of further constituent of the stem bark of G. cornea collected ia Bogor. Isolation and purification have been carried out by vacuum liquid chromatography and open column chromatography by using silica gel adsorbent and gradient eluting system of n-hexane, ethyl acetate, and methanol.The structure of this compound was deduced on basis of spectroscopic data 'H NMR, 13C NMR, and DEPT and comparison with the reported data.This compord has been reported from others species.
