Objective: To study the chemical constituents from the leaf of Hydnocarpus hainanensis.
Methods: Compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography, their structures were identified by spectroscopic analysis.
Results: Nine compounds were isolated and identified as glutinol (I), fernenol (II), lupeol (III), a-armyrin (IV), 2, 9-dimethyldeca-2, 8-diene (V), phytenal (VI), phytol (VII), 3, 7, 11,15-tetramethylhexadecane-1,2-diol ( VI), 3, 5-dimethoxy-4-hydroxybenzaldehyde (IX).
Conclusion: All the compounds are isolated from this plant for the first time.
