[Chemical Constituents from Drypetes hainanensis Stems and Leaves].Zhong Yao Cai. 2015 Oct; 38(10):2095-7.ZY
To study the chemical constituents from the stems and leaves in Drypetes hainanensis.
The constituents were isolated and purified by various chromatography, and the structures were identified by extensive spectral analysis.
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).
All the compounds are isolated from this plant for the first time.
