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)。Objective: To study the antihyperlipidemia effective constituent of PolygalafaUax Hemsl. Method: Column chromatographic techniques were employed for isolation and purification of chemical constituents of the plant and the structures were elucidated by IR, NMR and MS spectroscopy. Result: Four triterpenoid saponins were isolated and determined as 3-O-β -D-glueopyranosyl- ( 1→2 ) -β -D-glueopyranosyl presenegenin 28-O-β - D-xylopyranosyl- ( 1 →4 ) -α -L-rhamnopyranosyl-(1→2) -β-D-fueopyransoyl ester ( Ⅰ ), 3-O-β-D-glucopyranosyl - ( 1 →2 ) -β-D-glucopyranosyl presenegenin 28-O-β-D-xy-lopyranosyl-( 1 →4 ) -α-L-rhamnopyranosyl-( 1 →2 ) -(3-O-acetyl) -β-D-fueopyranosyl ester( II ), 3-O-β-D-glucopyranosyl -(1 →2 )-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl-( 1 → )-α-L-rhamnopyranosyl- ( 1 →2 )-( 4-O-acetyl )-β-D-fueopyranosyl ester (Ⅲ) and 3-O-β-D-glucopyranosyl-(1→2)-β-D-glueopyranosyl presenegenin 28-O-β-D-xylopyranosyl- ( 1→4) -α -L-rhamnopyranosyl- ( 1→2 ) - (3,4-diacetyl) -β-D-fueopyranosyl ester ( Ⅳ ) . Conclusions: The effective constituents of PolygalafaUax Hemsl. reduced blood lipid especially plasma TG markedly. The authors have studied the chemical constituents of effective constituent systematically for the first time.
