Abstract
This paper discusses the lipid of Helminthosporium oryzae and its fatty acid components. The total lipid was fractionated on a silicic acid column into nonpolar lipid (NL) and polar lipid (PL), by eluting first with chloroform and then methanol. NL accounted for over 80% of the total lipid. The principal component of NL was triglyceride. PL was principally composed of ceramidemonohexoside (CMH), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and unidentified lipids. The main fatty acid components of H. oryzae were C16:0, C18:0, C18:1 and C18:2.
The existence of CMH in the PL fraction has not been reported previously in plant pathogenic fungi.
