Clupanodon melanostica

C22H34O2, Mr 330.51. Pale yellow liquid, D. 0.937, mp. -78 °C, bp. 331 °C. C. is a docosapentaenoic acid (DPA) of the o)3-series with an unusual distribution of the C=C double bonds it was first isolated from the Japanese sardine Clupanodon melanostica), the oil of which contains ca. 8% C. The DPA of the ft>3-series normally formed in animals is (a//-Z)-7,10,13,16,19-DPA built from eicosapentaenoic acid by chain lengthening. The corresponding fatty acid of the (u6-series is (aH-Z)-4,7,10,13,16-DPA, formed as metabolic product from linoleic acid. Many fish and fish liver oils contain glycerol esters of C. in varying amounts, e.g. sardine oil 2.8%, mackerel oil 0.6%, anchovy oil 1.2%, and herring oil 0.4% as well as cod-liver oil 10%. 

Data on California sardine, also known as pilchard oil, from the fish Sardinops caerulea, are limited. Japanese sardine oil is obtained from Clupanodon melanostica (Table 3.183) (Ackman and Sipos, 1964 Itoh and Fukuzumi, 1963).
