Abstract

From methanol extract of Acanthopnanax senticosus, six platelet anti-aggregating compounds, chiisanogenin (1), chiisanoside (2), ursolic acid (3), oleanolic acid (4), b-sitosterol (5) and daucosterol (6) were isolated. All of the isolated compounds showed dose-dependent inhibitory activities to rat platelet aggregation induced by all the agonist employed. Compound 1 showed about 50 folds higher potency than acetylsalicylic acid (ASA) on U46619 induced platelet aggregation (IC$\sub$50/ : 6.21 ${\mu}$M) and 10 ∼ 20 folds higher effect than ASA on epinephrine and arachidonic acid (AA) induced aggregation (IC$\sub$50/ ; 2.50 and 4.81 ${\mu}$M, respectively).
