目的 对中国沙棘Hippophae rhamnoides ssp. sinensis籽粕的化学成分进行研究。方法 采用多种色谱方法进行分离纯化，运用多种谱学方法鉴定化合物的结构。结果 从中国沙棘籽粕的70%乙醇提取物中分离得到3个化合物，分别鉴定为山柰酚-3-O-[(2E)-2, 6-二甲基-6-羟基-2, 7-辛二烯酰-(1→6)]-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖苷-7-O-[(2E)-2, 6-二甲基-6-羟基-2, 7-辛二烯酰-(1→3)]-α-L-吡喃鼠李糖苷（1）、山柰酚-3-O-[(2E)-2, 6-二甲基-6-羟基-2, 7-辛二烯酰-(1→6)]-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖苷-7-O-[(2E)-2, 6-二甲基-6-羟基-2, 7-辛二烯酰-(1→2)]-α-L-吡喃鼠李糖苷（2）、异鼠李素-3-O-β-D-芸香糖苷（3）。结论 化合物1和2均为新的黄酮苷，分别命名为沙棘黄酮苷A和沙棘黄酮苷B。

Objective To study the chemical constituents in the seed residue of Hippophae rhamnoides ssp. sinensis. Methods Various chromatographic methods were employed to isolate the compounds and their structures were established by detailed spectroscopic analysis. Results Three compounds were isolated from 70% ethanol extract from the seed residue of H. rhamnosides ssp. sinensis and identified as kaempferol-3-O-[(2E)-2, 6-dimethyl-6-hydroxy-2, 7-octadienoyl-(1→6)]-β-D-glucopyranosyl-(1→2)-β-D- glucopyranoside-7-O-[(2E)-2, 6-dimethyl-6-hydroxy-2, 7-octadienoyl-(1→3)]-α-L-rhamnopyranoside (1), kaempferol-3-O-[(2E)-2, 6- dimethyl-6-hydroxy-2, 7-octadienoyl-(1→6)]-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside-7-O-[(2E)-2, 6-dimethyl-6-hydroxy-2, 7- octadienoyl-(1→2)]-α-L-rhamnopyranoside (2), and isorhamnetin-3-O-β-D-rutinoside (3). Conclusion Compounds 1 and 2 are new flavonoid glycosides, named seabuckthorn flavonoid glycoside A and seabuckthorn flavonoid glycoside B, respectively.
