The roots of these plants have been used as traditional Chinese medicines or folk love herbs. Codonopsis xundianensis Wang ZT et Xu GJ grows in Yunnan Province and its roots are often used as a tonic. In this paper, we report the isolation and structural elucidation of chrysoeriol (1), tricin (2), wogonin (3) and luteolin (4) from the roots of Codonopsis xundianensis. Compounds 1-3 were found in Codonopsis for the first time.展开更多
