白芍与赤芍含有的低极性成分不同,后者特异性含有齐墩果酸(1)与山楂酸样物质(2),但对化合物2尚不清楚。本次探讨化合物2,在明确其结构的同时,对其有效性亦进行了探讨,并报告了以超临界流体提取/吸附组合式高效率地分离出芍药的各种成分。 结果:①化合物体:C_(30)H_(48)O_4(M~+472),mp>300℃,IRμcm~(-1);3440,1694,~1H-NMRδppm;5.52(1H),4.20(2H),3.74(1H),与标准品常春藤皂甙元一致。②角叉
White peony is different from erythrosin, which contains a low-polar component. The latter specifically contains oleanolic acid (1) and hawthorn acid-like substance (2), but it is not known for compound 2. This time, compound 2 was studied, and its effectiveness was also discussed while clarifying its structure. It was reported that various components of peony were isolated with high efficiency by supercritical fluid extraction/adsorption combination. RESULTS: 1 Compounds: C 30 H 4 O 4 (M~+472), mp>300°C, IRμcm -1, 3440,1694, ~1H-NMRδ ppm, 5.52(1H), 4.20 2H), 3.74 (1H), consistent with the standard ivy acacia. 2 forks
