Abstract： In order to study the chemical constituents in the leaves of Champereia manillana var. longistaminea, the chemical composition was analyzed by the silica gel column chromatography (CC), thin-layer chromatography (TLC), dextran gel column chromatography (Sephadex LH-20), reversed-phase silica (RP-18) gel column chromatography and high performance liquid chromatography (HPLC). The ethyl acetate extraction part of the ethanol extraction was separated and 6 monomer compounds were obtained. The structures of these compounds were identified using nuclear magnetic resonance spectroscopy (NMR), high resolution mass spectrometry (HR-ESI-MS) and the data of the literature. Six compounds were elucidated as Taraxerol (1), 1H-indole-3-carboxylic acid (2), (24R)-cycloartane-3β,24,25-triol (3), (24R,S)-3β-24,31-Epoxy-24-methylcycloartane(4),1-O-linolenoyl-3-O-β-D-galactospyranosyl-snglycerol (5), and Hyloglyceride (6). All compounds 1-6 were isolated from this plant for the first time.
