Quantitative variation of fatty acid composition in seed oil from baobab (Adansonia digitata L.) wild populations in sub-Sahara Africa

Baobab (Adansonia digitata L., Malvaceae) seed oil contains Fatty Acids (FAs) with commercial and cosmeceutical value. The influence of provenance and geographical region on FAs profile and content of seed oil from baobab wild populations in sub-Saharan Africa (SSA) was assessed in this study. The F...

Description
Summary:Baobab (Adansonia digitata L., Malvaceae) seed oil contains Fatty Acids (FAs) with commercial and cosmeceutical value. The influence of provenance and geographical region on FAs profile and content of seed oil from baobab wild populations in sub-Saharan Africa (SSA) was assessed in this study. The FA profiles were determined as fatty acid methyl esters (FAME) by Gas Chromatography (GC). Generally, the seed oil contained 17–22% saturated fatty acids (SFA), 32–38% monounsaturated fatty acids (MUFA) and 22–26% polyunsaturated fatty acids (PUFA). Palmitic acid (C16:0) was the most abundant SFA, while oleic (C18:1) and linoleic acid (C18:2, LA) were the dominant MUFA and PUFA, respectively. There existed significant (p  Palmitic > Linoleic > Stearic > Linolenic.•Significant variation in FA content across ecological provenances.•Accessions from Malindi provenance had the highest linolenic acid content.•Potential for seed oil extraction, conservation and breeding programmes.
