Inhibition of Lens Aldose Reductase by Biflavones fromOuratea spectabilis
摘要:
Two biflavonoids were isolated from the EtOH extract from leaves of Ouratea spectabilis. Their structures were established to be the novel 6,6″-bigenkwanin and 7,7″-dimethoxyagathisflavone on the basis of spectroscopic data. The inhibition of bovine lens aldose reductase exerted by these biflavones has been studied.
