Distribution of fatty acids in triacylglycerols from ungrafted Desi Mango (Mangifera indica)‎ kernel lipids

الملخص EN

The lipids of engrafted 'Desf mango (Mangifera indica) kernel were extracted with chloroform /methanol, purified and triacylglycerols (82.6%) were separated by thin layer chromatography (TLC).

The pure triglycerides are fractionated into five bands by 25% silver nitrate-impregnated thin layer chromatography (Ag-TLC).

The composition and position of fatty acids at a, a' and P-positions of fractionated/unfractionated triacylglycerols were determined by the use of pancreatic lipase, sodium tetra borate-impregnated thin layer chromatography (borate-TLC) and gas liquid chromatography (GLC).

The highest percentage of the most saturated band was 55.6% which comprised of, src-l, 3-disaturated-2-oleoglycerols and Sn-l (3) saturated-2, 3(1, 2)-dioleoylglycerols.

The oleic, linoleic and linolenic acids occupied β-position depending upon comparatively higher percentage of unsaturated fatty acids in specific fraction.
