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-beta-ferulic acid ether (1), marinnone A (16) and marinnone B (17), along with eighteen known compounds as threo-guaiacylglycerol-beta-ferulic acid ether (2), eleutheroside E2 (3), (+)-lirioresinol A (4), dihydroxymethyl-bis (3, 5-dimethoxy-4-hydroxyphenyl) tetrahydrofuran-9-O-beta-glucopyranoside (5), (+)-lyoniresinol 3a-O-beta-D-glucopyranoside (6), (-)-lyoniresinol 3a-O-beta-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).
CONCLUSIONS
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.
