Abstract:

Two minor acetophenones, 2,5-dihydroxy-4-methoxyacetophenone ( 2) and 2,5-dihydroxy-4-methylacetophenone (7) from Paeonia species were found to selectively inhibit the aggregation of rabbit platelets induced by arachidonic acid. They were more potent than the major compound, paeonol (1), and 7 also inhibited the formation of TXA₂ and PGD₂ from arachidonic acid.

Key words:

Acetophenones - Paeonia species - Paeoniaceae - Antiplatelet aggregation
