Received Date: 29 January 2007

Two new acetylated flavonoid diglycosides, scutellarein-5-O-[α-L-rhamnopyranosyl-(1→4)-β-D-6-O-acetylglucopyranoside](1), apigenin-5-O-[α-L-rhamnopyranosyl-(1→2)-β-D-3, 6-di-O-acetylglucopyranoside] (2), were isolated from the leaves of Cephalotaxus sinensis. Their structures were determined by chemical and spectroscopic methods including HR-FAB-MS, ¹H-¹H COSY, HSQC and HMBC experiments.
