High performance liquid chromatography (HPLC) was applied to the analysis of triglycerides of rice bran oil. The triglycerides were clearly separated in five peaks by HPLC on a column packed with ${\mu}-Bondapack$ C18 using methanol-chloroform mixture as a solvent. Compositions of the triglyceride and fatty acid of the fraction was also analyzed by gas liquid chromatography (GLC). Each of these collected fractions gave three to four peaks in the GLC chromatograms according to the carbon number of the triglyceride. The fitty acid compositions of these triglycerides were mainly composed of C16:0, C18:1 and C18:2 fatty acids. The major triglycerides of the rice bran oil were found to be those of (C16:0, C18:1, C18:2;16.64%), $(2{\times}C18:1,\;C18:2;16.18%)$, $(3{\times}C18:1;13.7%)$, $(C16:0,\;2{\times}C18:1;12.77%)$,$(C18:1,\;2{\times}C18:2;9.16%)$ and $(C16:0,\;2{\times}C18:2;6.42%)$
