[Compounds from roots of Chirita fimbrisepala Hand.-Mazz]
Abstract
Objective:
To study the chemical constituents the roots of Chirita fimbrisepala.
Method:
The constituents were extracted with solvent, separated and purified with chromatographic methods, identified by NMR, MS, UV, IR and physical-chemical constants.
Result:
Three flavonoids mahuangchiside(I), hispidulin (II) and kaempferol(III) were isolated with daucosteral(IV).
Conclusion:
I is a new compound elucidated as hispidulin-7-O-beta-D-xylopyranosyl-(1-->2)-beta-D-xylopyranoside, named mahuangchiside, II and III were isolated for the first time from the family Gesneriaceae, and IV was isolated for the first time from the genus Chirita.
