对中药肉苁蓉Sarcopyramis bodinieri var.结果分离出两种新的黄酮醇糖苷，即异鼠李素-3-O-（6“-O-E-阿魏酰）-β-D-吡喃葡萄糖苷（1）和异鼠李素-3-O-（6”-O-E-阿魏酰）-β-D-吡喃半乳糖苷（2）。此外，还得到了四个已知化合物，槲皮素-3-O-（6“-乙酰基）-β-D-吡喃葡萄糖苷（3）、异鼠李素-3-O-（6”-乙酰基）-β-D-吡喃葡萄糖苷（4）、槲皮素-3-O-（6“-O-E-对香豆酰基）-β-D-吡喃葡萄糖苷（5）和异鼠李素-3-O-（6”-O-E-对香豆酰基）-β-D-吡喃葡萄糖苷（6）。通过广泛的光谱分析确定了新分离物的结构。
Detailed chemical investigation of the herb Sarcopyramis bodinieri var. delicate resulted in the isolation of two new flavonol glycosides, namely, isorhamnetin-3-O-(6 ''-O-E-feruloyl)- beta-D-glucopyranoside (1) and isorhamnetin-3-O-(6 ''-O-E-feruloyl)-beta-D-galactopyranoside (2). In addition, four known compounds, quercetin-3-O-(6 ''-acetyl)-beta-D-glucopyranoside (3), isorhamnetin-3-O-(6 ''-acetyl)-beta-D-glucopyranoside (4), quercetin-3-O-(6 ''-O-E-p-coumaroyl)-beta-D-glucopyranoside (5), and isorhamnetin-3-O-(6 ''-O-E-p-coumaroyl)beta-D-glucopyranoside (6) were obtained. The structures of the new isolates were determined by extensive spectroscopic analysis.
