In-vitro characterization and biological properties of polyphenols extract of ripe garden egg (Solanum gilo)
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
This study sought to investigate and compare the HPLC/DAD characterization, nutrient composition of ripe and unripe garden egg fruits to see its potentials for use in animal feed and in industrial processes. Analyses were carried out on Solanum gilo ripe (SGR) and Solanum gilo unripe (SGU) dried samples. Proximate analysis and minerals such as (Ca, Na, K, Mg, Zn) as well as some anti-nutritional factors (phytates, tannins) were carried out on the powdered samples. Polyphenols content were identified and quantified using HPLC-DAD. Total phenols, total flavonoids and vitamin C content was determined, while its antiradical assay was examined as typified 1,1-diphenyl-2 picrylhydrazyl [DPPH] and 2,2- Azinobis (3-ethylbenzo-thiazoline-6-sulfonate [ABTS]. Results of the study revealed an increased in fat and crude fibre content while a slight reduction was reported in protein content but no significant changes was reported in the total carbohydrate content. HPLC-DAD analysis showed that gallic acid was the most abundant phenolics present. There was increased in some of the flavonoids due to ripening such as Ellagic acid, Isoquercitrin, Quercetrin and Kaempferol. The total phenols, flavonoids increased in SGR, there was no change in DPPH scavenging ability while ABTS scavenging ability increased with the SGR. It can be concluded that ripe garden eggs which is usually discarded could be of use as an excellent livestock feed source/additives
