Abstract:
Chemical constituents of ethyl acetate extract of Illicium burmanicum were isolated and purified by various chromatographic methods,including Silica gel, Sephadex LH-20, C18 reverse-phased silica gel, Preparative TLC and Preparative HPLC. Their structures were identified by spectral analysis including NMR and MS data. Fourteen compounds were separated from I. burmanicum and their structures were identified as 7S,8R-erythro-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (1), 7R,8R-threo-4,7, 9,9'-tetrahydroxy-3,3 '-dimethoxy-8-O-4'-neolignan(2) ,polystachyol(3), (-) -massoniresinol(4), angustanoic acid F (5), trans-sobrerol(6), (3S,6R) -6,7-dihydroxy-6,7-dihydrolinalool (7), (3S, 6S) -6,7-dihydroxy-6,7-dihydrolinalool (8), 2,6-dimethoxy-4-allyl-phenol (9), 3,5-dihydroxy4-hydroxy benzaldehyde (10), 3-hydroxy4-methoxybenzaldehyde (11), methyl vanillate (12), shikimic acid ethylester (13) and beta-sitosrerol (14). Except compound 14, the rest thirteen compounds were separated from this plant for the first time.
