紫花松果菊水溶性成分研究

目的研究紫花松果菊的化学成分。方法用色谱法分离化合物，用波谱法鉴定其结构。结果从紫花松果菊分离得到5个化合物,其结构分别鉴定为2-(4-羟基苯基)乙基-O-α-L-鼠李糖基(1→6)-β-D-葡糖苷(1),(6S,9R)6羟基-3-酮-α-紫罗兰醇-9-O-β-D-葡糖苷(roseoside)(2),ampelopsisionoside (3),苯甲基-O-β-木糖基(1→6)-β-D-葡糖苷(β-primererosides)(4),苯甲基-O-β-D葡糖苷(5)。结论化合物1为新化合物，命名为紫花松果菊苷A(echipuroside A)，其余化合物均为首次从本属植物获得。

STUDIES ON WATER-SOLUBLE CONSTITUENTS OF ECHINACEA PRUPUREA

AIM: To study the water-soluble constituents of Echinacea purpurea. METHODS: The compounds were isolated by chromatography method and their structures were identified on the basis of spectral analyses. RESULTS: Five compounds were identified as 2-(4-hydroxylphenyl)-ethyl-O-alpha-L-rhamnopy-ranoasyl-(1-->6)-beta-D- glucopyranoside, named echipuroside A 1); (6S, 9R)-6-hydroxy-3-one-alpha-inonol-9-O-beta-D-glucopyranoside 2), ampelopsisionoside 3); phenylmethyl-6-O-beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranoside 4) and phyenylmethyl-beta-D-glucopyranoside 5). CONCLUSION: Compound 1 is a new compound, the others were isolated from this plant for the first time.
