Abstract

Chromatographic separation of the 80% MeOH extract of the leaves of Ilex rotunda (IR) led to isolation of two new hemiterpene glycosides, tentatively named as rotundarpenoside A (1) and rotundarpenoside B (2), along with five known caffeoyl derivatives (3-7). The chemical structures of these compounds were elucidated using 1D/2D NMR, HR-MS, and the absolute configuration was confirmed by Mosher's method. In order to evaluate their anti-oxidative activities, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and xanthine oxidase superoxide scavenging activities (NBT) were determined.
