Abstract

Lipid levels in the tissues of liver and intestines of O.bartrami amounted to 40.0% and 1.5%. The new compounds was found to be ethyl acylates, from a deduction of their detailed $^1H-nuclear$ magnetic resonance(NMR) and $^{13}C-NMR$ as well as infra red spectra (IR). The fatty acid composition of total lipids were mainly composed of C16:0(19.0%), C18:1(16.2%) and $C22:6{\omega}3$(15.7%), followed by C20:1(9.4%), C22:1(6.4%) and C18:0(5.4%). New compound A and B were seemed to derived from the cleavage of glycerol moieties of triglycerides by microbial activities during storage in a frozen state. Compound A contained C16:0(38.2%), C18:1(13:4%), C20:1(13.3%) and C22:1(11.7%) as major components, while compound B predominantly comprised polyunsaturated fatty acid such as $C20:5{\omega}3$ (41.2%) and $C22:6{\omega}3$(36.1%). In both compounds small amounts of odd numbered fatty acids were also detected ($3.8{\sim}2.2%$).
