黄花倒水莲降血脂活性成分研究

摘要

从黄花倒水莲Polygala fallaxHem sl.根的降血脂有效部位中分离得到四个皂苷类化合物,分别鉴定为3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl presenegen in 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)--βD-fucopyransoyl ester(Ⅰ)、3-O--βD-glucopyranosyl-(1→2)--βD-glucopyranosyl presenegen in 28-O-β-D-xy-lopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-(3-O-acetyl)-β-D-fucopyranosyl ester(Ⅱ)、3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl presenegen in 28-O-β-D-xylopyranosyl-(1→4)--αL-rhamnopyranosyl-(1→2)-(4-O-acetyl)-β-D-fucopyranosyl ester(Ⅲ)和3-O-β-D-glucopyranosyl-(1→2)--βD-glucopyranosyl presenegen in 28-O-β-D-xylopyrano-syl-(1→4)-α-L-rhamnopyranosyl-(1→2)-(3,4-d iacetyl)--βD-fucopyranosyl ester(Ⅳ)。
