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