Abstract
|
|
|
Two new coumarin glucosides, 11-O-¥â-D-glucopyranosyl thamnosmonin (1) and 12-O-¥â-D-glucopyranosyl gosferol (2), were isolated from the roots of Angelica apaensis. Their structures were elucidated spectroscopically. Both compounds showed weak inhibitory effects on rabbit platelet aggregation induced by PAF, AA and APD.
