从秦岭大黄RheumqinlingenseY.K.Yang，D.K.ZhangetJ.K.Wu根茎的乙醇溶性部分分得10个化合物，经光谱学鉴定，它们的结构分别为大黄酚（chrysophanol，Ⅰ）、大黄素甲醚（physcione，Ⅱ）、芦荟大黄素（aloe-emodin，Ⅲ）、大黄素（emodin，Ⅳ）、大黄酚8－O-β-D-吡喃葡萄糖苷（chrysophanol8－O-β-D－glucopyranoside，Ⅴ）、大黄素甲醚8－O-β-D-吡喃葡萄糖苷（physcione8－O-β-D－glucopyranoside，Ⅵ）、芦荟大黄素8－O-β-D-吡喃葡萄糖苷（aloe－emodin8－O-β-D-glucopyranoside，Ⅶ）大黄素8－O-β-D-吡喃葡萄糖苷（emodin8－O-β-D－glucopyranoside，Ⅷ）、大黄酸（rhein，Ⅸ）和大黄酚8－O-β-D－（6′－O-丙二酸单酰基）吡喃葡萄糖苷[chrysophanol8－O-β-D－（6′－O－malonyl）glucopyranoside，Ⅹ]。其中化合物Ⅹ系新化合物，Ⅵ和Ⅷ为首次从秦岭大黄中分得。
From the ethanol-soluble fraction of Rheumqinlingense Y.K.Yang and DKZhangetJ.K.Wu of rhubarb from Qinling Mountains, 10 compounds were identified. Their structures were identified by spectroscopic analysis as chrysophanol (I) and physcione. , II), aloe-emodin (III), emodin (IV), chrysophanol 8-O-β-D-glucopyranoside (V) , physcione8-O-β-D-glucopyranoside (VI), aloe-emodin-8-O-β-D-glucopyranoside (aloe-emodin8) -O-β-D-glucopyranoside, VII) Emodin 8-O-β-D-glucopyranoside (VIII), rhein (IX), and chrysophanol 8 -O-β-D-(6’-O-malonyl)glucopyranoside [chrysophanol8-O-β-D-(6’-O-malonyl) glucopyranoside, X]. Among them, Compound X is a new compound, and VI and VIII are firstly obtained from the rhizosphere of Qinling.
