Phytochemical Evaluation of Dry, Wet and Oil of Leaf of Annona muricata for Medicinal Activities

Abstract

Qualitative and quantitative phytochemical analyses were carried out on the dry, wet and oil of the leaves of Annona muricata using standard methods. The phytochemicals detected in the aqueous extracts of dry, wet and oil of the leaf were flavonoids, cardiac glycoside, tannins, saponin, terpenoids and steroids. The result of the quantitative analyses showed that oil extract had the highest total phenolics content (TPC: 3.09 mg GEA/g), total flavonoids content (TFC: 16.67 mg QE/g), total saponins content (TSC: 16.86 mg DE/100g) and Total tannins content (TTC: 1.13 mg GAE/g) followed by dry leaf extract (TPC: 1.66 mg GEA/g; TFC: 7.067 mg QE/g; TSC: 14.55 mg DE/100g; and TTC: 0.78 mg GAE/g) and the least was recorded for the wet leaf extract (TPC: 0.83 mg GEA/g; TFC: 3.92 mg QE/g; TSC: 12.07 mg DE/100g; and TTC: 0.44 mg GAE/g). The findings indicate that an Annona muricata leaf is a potential source of phytomedicine with the oil rich in phytochemicals, than dry and wet leaf extracts and any other biochemical analyses should be done using the oil.
