    Abstract:
    OBJECTIVE: To study the chemical constituents in the stem bark of Styrax perkinsiae. METHODS: The chemical constituents were separated and purified by chromatographic methods after solvent extraction and identified by spectroscopic analyses. RESULTS: Ten lignans were isolated from the stem bark of Styrax perkinsiae and identified as following: pinoresinol 4-O-β-D-glucopyranoside (1), matairesinoside (2), styraxlignolide B (3), 3- (β-D-glucopyranosyloxymethyl)-2-(4-hydroxy-3-methoxyphenyl)-5-(3-hydroxypropyl )-7-methoxy-(2R , 3S) -dihydrobenzofuran (4), burselignan (5), (+) -neo-olivil (6), threo-1-(4-hydroxy-3-methoxyphenyl )-2-[ 4-(3-hydroxypropyl)-2-methoxyphenoxy]-1, 3-propanediol (7), erythro-1-(4-hydroxy-3-methoxyphenyl )-2-[ 4-(3-hydroxypropyl )-2-methoxyphenoxy ] -1 ,3-propanediol (8), isolariciresinol(9) and (+) -lariciresinol (10). CONCLUSION: Compounds 5 - 10 are isolated from the plants of Styrax genus for the first time.
