octadecadienoic-acid and decane

Chemical investigation of Semen Persicae has led to the 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). Amongst these, compound 7 is a new lipid. Their structures were elucidated by chemical and extensive spectral analysis. Their anticoagulative activities were also evaluated in vitro, which showed that petroleum ether extract and compounds 5-6 could significantly prolong thrombin time while methanol extract could obviously inhibit platelet aggregation.
