    Structure Identification:
    Journal of Shenyang Pharmaceutical University, 2010,10:788-792.
    Separation and identification of new sucrose esters from root of Polygala tenuifolia Willd[Reference: WebLink]
    To study the constituents of the extract from the root of Polygala tenuifolia Willd.
    METHODS AND RESULTS:
    The chemical constituents were isolated by silica,Sephadex LH-20 gel column chromatography and HPLC.Chemical characters and spectroscopic analysis were employed for the structural identification. 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.
