Acylated Flavone C-glycosides from Trollius ledebouri Reichb

A new acylated C-glycosylflavone (1) was isolated from Trollius ledebouri Reichb together with nine known C-glycosyflavones (2-10).The structures were elucidated by spectroscopic methods,including HRMS,IR,1H and 13C NMR and 2D experiments (COSY,HMQC and HMBC).The anti-inflammatory activities of C-glycosyflavones were tested on TPA-induced mice ear edema (in vivo).
