The antipatharian Leiopathes sp., collected around Saint Paul Island, is shown here to contain, in relatively high amounts, the novel fatty acid leiopathic acid ( = (+)‐(10 R ,7 Z ,11 E ,13 Z ,16 Z ,19 Z )‐10‐hydroxy‐7,11,13,16,19‐docosapentaenoic acid; (+)‐ 1 ), besides (+)‐(8 R ,5 Z ,9 E ,11 Z ,14 Z ,17 Z )‐8‐hydroxy‐5,9,11,14,17‐icosapentaenoic acid ((+)‐ 11 ) and (+)‐(8 R ,5 Z ,9 E ,11 Z ,14 Z ,)‐8‐hydroxy‐05,9,11,14‐icosatetraenoic acid ((+)‐ 16 ) and their ethyl ester (+)‐ 2 , (+)‐ 12 , and (+)‐ 17 .
