摘要
从沙漠绢蒿全草中分离得到一个双黄酮苷类化合物芹菜素-7—O-β-D-葡萄糖苷-（3′-O-7″）-槲皮素-3″-甲氧基。通过2DNMR（HMQC、HMBC）和与木犀草素-7-O-吡喃葡萄糖苷、槲皮素-3-甲氧基的核磁数据的对比对该化合物进行了NMR全归属，并重新调整了13C信号归属。
A biflavonoid glucoside was isolated from the whole plant of Seriphidium santolium Poljak, and its structure has been determined to be apigenin-7-O-β-D-glucopyranoside-（ 3′-O-7＂）-quercetin-3＂-methoxyl with MS and NMR measurements. Complete chemical shifts assignment for this compound was achieved on the basis of 2D NMR analysis and its 13C NMR signals were reassigned. The 13C chemical shifts of this compound were compared to luteolin-7-O-β-D-glucoside and quercetin-3-methoxyl
