【Abstract】 Objective:To investigate the chemical constituents from Avicennia marina.Methods:The isolation and purification of the CH2Cl2 and n-BuOH fractions of this plant were performed,and the chemical structures were elucidated by spectral analysis as well as comparison of their spectral data with literature values.Results:Three novel compounds were obtained and identified as erythro-guaiacylglycerol-β-ferulic acid ether(1),marinnone A(16) and marinnone B(17),along with eighteen known compounds as threo-guaiacylglycerol-β-ferulic acid ether(2),eleutheroside E2(3),(+)-lirioresinol A(4),dihydroxymethyl-bis(3,5-dimethoxy-4-hydroxyphenyl) tetrahydrofuran-9-O-β-glucopyranoside(5),(+)-lyoniresinol 3a-O-β-D-glucopyranoside(6),(-)-lyoniresinol 3a-O-β-D-glucopyranoside(7),epi-pinoresinol(8),leucoseceptoside A(9),jionoside C(10),salsaside A(11),ilicifolioside A(12),acteoside(13),isoacteoside(14),ethyl ferulate(15),avicennone D(18),avicenone E(19),avicennol C(20),and stenocarpoquinone B(21).Conclusion:Three new compounds(1,16 and 17) were obtained and thirteen known compounds,2-12,14 and 15 were isolated from Avicennia genus for the first time.更多还原
