Chemical constituents from the aerial parts of with their inhibitory activities on α-glucosidase.

A new aurone glycoside named licoagroaurone 6---ʟ-arabinopyranoside (), together with six known compounds (-), was isolated from EtOAc-soluble extract of the aerial parts of Their structures were elucidated on the basis of spectroscopic methods. All compounds were evaluated for their inhibitory activities against α-glucosidase . Among them, compounds and showed significant inhibitory activities on α-glucosidase with the IC values of 47.1 and 57.7 μM, respectively.
