摘      要：A new flavone glycoside, named mahuangchiside, was isolated from the root of Chirita fimbrisepala Hand.-Mazz. The structure was elucidated as 5,4 -dihydroxy-6-methoxyflavone-7-O-beta-D-xylopyranosyl(1--2)-beta-D-xylopyranoside on the basis of spectral analysis (H-1-H-1 COSY. C-13-H-1 HETCOR and HMBC) and chemical evidence.
