    Separation and identification of new sucrose esters from root of Polygala tenuifolia Willd.[Reference: WebLink]
    Results Eleven compounds were obtained and their structures were identified as sibiricose A5(1),tenuifolioside A(α-D-glucopyranoside,3-O-[(2Z)-3-(4-hydroxy-3-methoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,2),tenuifolioside B(α-D-glucopyranoside,3-O-[(2E)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,3),tenuifolioside C(α-D-glucopyranoside,3-O-[(2Z)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,4),sibiricose A6(5),glomeratose A(6),Sibiricaxanthone B(7),polygalaxanthone Ⅺ(8),1,2,3,7-tetramethoxyxanthone(9),onjixanthoneⅡ(10),and polygitol(11).Conclusions Compounds 24,named tenuifolioside A-C respectively,are new sucrose esters which have not been reported before.
