Abstract

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.
