Y. Okada et al., SEARCH FOR NATURALLY-OCCURRING SUBSTANCES TO PREVENT THE COMPLICATIONS OF DIABETES .2. INHIBITORY EFFECT OF COUMARIN AND FLAVONOID DERIVATIVES ON BOVINE LENS ALDOSE REDUCTASE AND RABBIT PLATELET-AGGREGATION, Chemical and Pharmaceutical Bulletin, 43(8), 1995, pp. 1385-1387
An EtOAc extract of Artemisiae Capillari Spica inhibited both bovine l
ens aldose reductase (bovine-LAR) and rabbit platelet aggregation, Two
simple coumarins, scoparone (1) and scopoletin (2), and three flavono
ids, capillarisin (21), cirsimaritin (22) and rhamnocitrin (23), were
isolated from this extract, Scoparone (1) and scopoletin (2) exhibit a
potent inhibitory effect on rabbit platelet aggregation induced by fo
ur types of agent, ADP, PAF, sodium arachidonate and/or collagen, Capi
llarisin (21) exhibits a potent inhibitory effect on bovine-LAR, In ad
dition, thirteen simple coumarins, five coumarin glycosides and two fl
avonoids were tested for their inhibitory effect against bovine-LAR an
d rabbit platelet aggregation.
