Abstract:
Object To study the chemical constituents from the whole plant of Swertia przewalskii Pissjauk Methods The constituents were isolated on silica gel column chromatography and their structures were identified by spectral and chemical analysis Results Fifteen compounds were isolated and identified as 1, 7 dihydroxyl 3, 8 dimethoxyxanthone (Ⅰ), 1, 8 dihydroxyl 3, 7 dimethoxyxanthone (Ⅱ), 1, 7, 8 trihydroxyl 3 methoxyxanthone (Ⅲ), 1, 3, 7, 8 tetrahydroxyxanthone (Ⅳ), 1 O ? D glucopyranosyl 7 hydroxyl 3, 8 dimethoxyxanthone (Ⅴ), 1 O ? D glucopyranosyl 8 hydroxyl 3, 7 dime thoxyxanthone (Ⅵ), 7 O ? D glucopyranosyl 1, 8 dihydroxyl 3 methoxyxanthone (Ⅶ), 1 O D xylo pyranosyl (1→6) ? D glucopranosyl] 7 hydroxyl 3, 8 dimethoxyxanthone (Ⅷ), 1 7 hydroxyl 3, 8 dimethoxyxanthone (Ⅷ), 1 O D xylopyranos yl (1→6) ? D glucopytanosyl] 8 hydroxyl 3, 7 dimethoxyxanthone (Ⅸ), 8 8 hydroxyl 3, 7 dimethoxyxanthone (Ⅸ), 8 O D xylopyanosyl (1→6) ? D glucopyranosyl] 1, 7 dihydroxyl 3 methoxyxanthone (Ⅹ), luteolin (Ⅺ),? sitosterol ( Ⅹ 1, 7 dihydroxyl 3 methoxyxanthone (Ⅹ), luteolin (Ⅺ),? sitosterol ( ⅩⅡ ), oleanolic acid ( ⅩⅢ ), ursolic acid ( ⅩⅣ ) and getiopicroside ( ⅩⅤ ), respectively Conclusion Compounds Ⅳ~Ⅷ, Ⅺ, ⅩⅡ , ⅩⅣ and ⅩⅤ were obtained from this plant for the first time
