【 摘 要 】

Phytochemical investigation of the ethanol extract of leaves, twigs and fruit shell of Lecythis pisonis Camb. revealed the presence of squalene, a- e b-amyrin, lupeol, 3b-friedelinol, ursolic and oleanolic acids, (E)-phytol, sitosterol, stigmasterol, campesterol, quercetin-3-O-rutinoside and kaempferol-3-O-rustinoside. Structural elucidation was achieved using ultra violet (UV), nuclear magnetic resonance (NMR), and mass spectrometry. This is the first report of the occurrence of flavonoids, together with squalene, lupeol and campesterol in L. pisonis. The EtOH extract of the leaves showed high antioxidant activity, which can be associated in part with the high level of phenols and flavonoids.
