(Vietnamese name; L.), which belongs to the family, is an evergreen and perennial tree that is widely cultivated in Southeast Asia. In Vietnam, leaves of the species are used as an ordinary vegetable in many regions. The aim of this research is to investigate the chemical constituents of G. leaves collected from Lam Dong province, Vietnam. The fresh leaves were collected, dried, cut into small species, and extracted with ethanol to the extract. By using the column chromatography method together with thin layer chromatography on a normal phase silica gel with different solvent systems on the extract of the dried leaves of G. L., we isolated five pure compounds. The structures of 1-5 were elucidated by analyzing nuclear magnetic resonance (NMR) data. The result was confirmed by comparison with publish data including (1), acid (2), acid (3), (4), and (5). To the best of our knowledge, compounds 1-3were isolated from this plant for the first time. This study is to provide a comprehensive overview of of G. , and possibly make recommendations for further research.
