The ether extract from the roots of angelica clahurica was found to inhibit bovine lens aldose reductase (BLAR0 activity in vitro by 100% at 100.mu.g/ml. Systematic fractionation of the ether soluble fraction and subsequent active frctions monitorede by bioassy led to isolation of four furanocoumarins, isoimperatorin (I0, imperatorin (II), ter-O-methyl byakangelicin (III) and byakangelicin (IV), among which compound III and IV were identified as potential AR inhibitors, their $IC_{50}$ values being $2.8{\mu}M{\;}and{\;}6.2{\mu}M$, respectively. Galactosemic cataract formation tors, in rats treated with 40 g/kg/day of galactose was blocked almost completely throughout the exeprimental periods up to 44 days by i.p. administrations of byakangelicin (IV) at 50 mg/kg/day. In coincidence with the inhibitory action on cataract formation, the galactitol accumulation in rats treated with byakangelicin (IV) was found to be markedly prevented by approximately 80.5% compared to those of the contro. These results indicate that byakangelicin (IV), as a main principle of this plant, possesses high potential for a clinically useful drug of the future which prevents and/or improves sugar cataract as well as diabetic complications.
