Abstract
The fat fromTheobroma bicolor
was analyzed for glyceride content by thin layer chromatography (TLC),
and for fatty acid composition and triglyceride (carbon number)
composition by gas liquid chromatography (GLC). The fat was then
separated into glycerides of different degrees of unsaturation by means
of silver nitrate TLC. Then, the bands were examined by GLC before and
after conversion to methyl esters. From the results obtained, the
distribution of the fatty acids on the individual glycerides was
calculated. The fat consisted of 96.5% triglyceride with only 2.5%
diglyceride and 1.7% free fatty acid. The major fatty acids present were
42.3% C18:0, 45,2% C18:1, and 6.0% C16:1. Most of the triglycerides
were of carbon number 52 (18.0%) and 54 (77.6%). The major triglycerides
were 38.6% 1-stearyl-2,3 diolein (SOO), 25.4% 2-oleyl-1,3 distearin
(SOS) and 13.8% 1-palmito-2-oleyl-stearin (POS). Only 44.3% of the fat
consisted of monounsaturated triglycerides.
