dc.description.abstractBACKGROUND: Cocos nucifera (L.) is an important plantation crop with immense but untapped nutraceutical potential. Despite its bioactive potential, the biochemical features of testa oils of various coconut genotypes are poorly understood. Hence, in this study, the physicochemical characteristics of testa oils extracted from six coconut genotypes – namely West Coast Tall (WCT), Federated Malay States Tall (FMST), Chowghat Orange Dwarf (COD), Malayan Yellow Dwarf (MYD), and two Dwarf × Dwarf (D × D hybrids) viz., Cameroon Red Dwarf (CRD) × Ganga Bondam Green Dwarf (GBGD) and MYD × Chowghat Green Dwarf (CGD) – were analyzed. RESULTS: The proportion of testa in the nuts (fruits) (1.29–3.42%), the proportion of oil in the testa (40.97–50.56%), and biochemical components in testa oils – namely proxidant elements Fe (34.17–62.48 ppm) and Cu (1.63–2.77 ppm), and the total phenolic content (6.84–8.67 mg GAE/100 g), and phytosterol content (54.66–137.73 mg CE/100 g) varied depending on the coconut genotypes. The saturated fatty acid content of testa oils (67.75 to 78.78%) was lower in comparison with that of coconut kernel oils. Similarly, the lauric acid (26.66–32.04%), myristic (18.31–19.60%), and palmitic acid (13.43–15.71%,) content of testa oils varied significantly in comparison with the coconut kernel oils (32–51%, 17–21% and 6.9–14%, respectively). Liquid chromatography–mass spectrometry (LC–MS) analysis revealed the presence of 18 phenolic acids in coconut testa oil. Multivariate analysis revealed the biochemical attributes that defined the principal components loadings. Hierarchical clustering analysis of the genotypes showed two distinct clusters. CONCLUSION: This study reveals the genotypic variations in the nutritionally important biochemical components of coconut testa oils. The relatively high concentration of polyunsaturated fatty acids (PUFA) and polyphenol content in testa oils warrant further investigation to explore their nutraceutical potential.
