1. Antithrombotic lipids
in the investion of the antioxidant effects of Semen Persicae isolation of decane (1), triolein (2), nonacosanoic acid (3), oleic acid ethyl ester (4), palmitic acid (5), oleic acid (6) and 15,16-dihydroxy-9Z,12Z-octadecadienoic acid 2,3-dihydroxypropyl ester (7), showed that petroleum ether extract and compounds 5-6 could significantly prolong thrombin time while methanol extract could obviously inhibit platelet aggregation(1).
2.  Antimutagenic effects

The mutagenicities of 3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole (Trp-P-1) and 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide (AF-2) were also inhibited by the extracts of Armeniacae semen and Persicae semen(2).
