摘要

A new flavone glycoside m.f. C3oH36O15, m.p. 252-253℃, [M]+ 636 (EIMS) was isolated from the acetone soluble fraction of the concentrated 95% ethanolic extract of the seeds of Bauhinia xylopyranosyl-(1→2)-α-L-rhamnopyranoside (1) by various colour reactions, chemical degradations and spectral techniques.
