摘要：

C-13 NMR analysis of hot water extracts from young leaves of Photinia glabra gave prominent signals unassignable to any known components. Guided by the characteristic C-13 NMR signals, a new glucoside ester was isolated. The structure of this compound was determined to be 4(S)-O-(6-O-caffeoyl-beta-D-glucopyranosyl)-2-pentanone by H-1 and C-13 NMR analyses and other chemical evidence.
