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-methoxy flavone-7-O-β-D-xylopyranosyl(1→2)-0-D-xylopyranoside on the basis of spectral analysis (1H-1 H COSY. 13C-1H HETCOR and HMBC) and chemical evidence.
