[Chemical Constituents from Drypetes hainanensis Stems and Leaves].

OBJECTIVE

To study the chemical constituents from the stems and leaves in Drypetes hainanensis.

METHODS

The constituents were isolated and purified by various chromatography, and the structures were identified by extensive spectral analysis.

RESULTS

Eleven compounds were isolated and identified as syringaresinol-4-O-glycoside (1), koaburaside (2), abietin (3) syringin (4), kelampayoside A (5), 7,7'-bis-(4-hydroxy-3,5-dimethoxyphenyl)-8,8'-dihydroxymethyl-tetrahydrofuran-4-O-β-glucopyranoside (6), amentoflavone (7), 3,4,5-trimethoxyphenyl-β-D-glucopyranoside (8),1,4-di-O-methyl-myo-inositol (9), glycerol (10) and succinic acid (11).

CONCLUSION

All the compounds are isolated from this plant for the first time.
