Elegaphenonoside, a new benzophenone O-rhamnoside, together with two known benzophenone O-glycosides, namely hypericophenonoside and neoannulatophenonoside, were isolated from the aerial parts of Hypericum elegans Stephan ex Willd. The structure of the new compound was established as 3',5',6-trihydroxy-4-methoxybenzophenone-2-O-alpha-L-rhamnopyranoside by means of chemical and physical evidence. In addition, the presence of kaempferol, quercetin, isoquercitrin, norathyriol, I-3,II-8-biapigenin, quercitrin, hyperoside and rutin were established in this plant.
优雅金丝桃苷，一种新的二苯甲酮O-鼠李糖苷，与两种已知的二苯甲酮O-糖苷，即金丝桃苯甲酮苷和新环纹金丝桃苷，从秀丽金丝桃（Hypericum elegans Stephan ex Willd.）的地上部分分离得到。通过化学和物理证据确定新化合物的结构为3',5',6-三羟基-4-甲氧基二苯甲酮-2-O-α-L-鼠李吡喃糖苷。此外，还确定了该植物中存在山柰酚、槲皮素、异槲皮苷、北欧山嵛菜醇、I-3,II-8-双芹菜素、槲皮苷、金丝桃苷和芦丁。
