Effect of Solvent Polarity Index on Fatty acid, Phytochemical and Antioxidant Profiles of Oleoresin Extracts from Monodora Myristica Seed

Abstract

Oleoresin is a coloured viscous liquid composed of oils and resins extract from spice biomass, its proven suitability as industrial raw material with immense application, has stimulated increased search for this oleochemical with novel content. Hence, the objective of this paper was to assess the effect of solvent polarity index on fatty acid, phytochemical and antioxidant profiles of oleoresin extracts from Monodora Myristica seed using appropriate standard techniques. The Results showed TEC ranges from (4.54-10.20%) and present MMOETH oleoresin with the highest total extractable matter, TPC, TFC, DPPH activity, TAC, IRC and terpenes content characterized by monoterpenes and sesquiterpenes. Phlobatannins and Anthraquinones were present in MMOETA and MMOETH M. Myristica seed oleoresins albeit lower in the former. The study indicates preponderance levels of sterols and fatty acids contents in MMOPTE relative to MMOCLF, and also presents these oleoresins with absence of tannins, saponins, phlobatannins, anthraquinones and cardiac glycosides. 50% inhibitory concentration (IC50) for TAC and DPPH radical scavenging activities presents MMOETA and MMOETH with greater antioxidant potential compared to ascorbic acid used as reference standard. The results showed that all the solvents were effective for extraction of oleoresin from M. Myristica seed with varied content suitable for recipes in food, non-food and pharmaceutical formulations.
