To study the chemical constituents in the twigs and leaves of Ervatamia hainanensis.Methods:
The chemical constituents were isolated by silica gel, ODS, Sephadex LH-20 column chromatographies, and preparative HPLC. The structures were elucidated on the basis of physicochemical properties and spectral analysis.Results:
Four lignans were isolated and identified as threo-7-O-ethylguaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (1), threo-guaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (2), erythro-guaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (3), and dehydrodiconiferyl alcohol (4).Conclusion:
Compound 1 is a new 8-O-4'-neolignan and named as hainanervaligan A (1), and compounds 2-4 are obtained from the plants of Ervatamia (A. DC.) Stapf for the first time.
