Fatty Acid Profile Analysis of Abci Somatic Hybrid Mushroom Strains using GC-MS Technique

Abstract

The fatty acid profile from fruit bodies of four somatic hybrid mushroom (AbCi) strains and their parent strains Calocybe indica var. APK2 and Agaricus bisporus were studied using GC-MS. The study showed that Palmitic acid and Stearic acid were the most abundant saturated fatty acids (SFA) and this ranged from 15.0 - 30.18% in the hybrids and parent strains. Among mono-unsaturated fatty acids (MUFA), Oleic acid was found abundantly in hybrids AbCi 6, AbCi 7 and AbCi 8 compared to any of the parents. Poly-unsaturated fatty acids (PUFA) dominated among all the hybrids than their parents and maximum PUFA was found in AbCi 7 (64.6 %).In hybrids (AbCi 7- 59.95 % and AbCi 9- 60.4 %) and parents Linoleic acid dominated. Overall the unsaturated fatty acids were at higher concentrations than saturated fatty acids in hybrids than in parent strains.
