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--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.
