Abstract

Kalanchoe pinnata is an important medicinal plant in Nigeria with numerous pharmacological activities. The present study investigates the antioxidant activity of alkaloid and flavonoid fractions of Kalanchoe pinnata leaves. Proximate and phytochemical analyses of the plant were conducted followed by evaluation of the antioxidant activity of the alkaloid and flavonoid fractions using 1,1-diphenyl-2-picryl-hydrazyl, 2,2’-azinobis(3-ethylbenzothiazolline)-6-sulfonic acid, phosphomolybdenum, cupric ion reducing antioxidant capacity, ferric reducing antioxidant power and nitric oxide inhibition assays. The proximate composition of Kalanchoe pinnata leaves confirmed its edibility particularly in respect of moisture (86.73%) and carbohydrate (7.05%) content. The results revealed the presence of phenol (12.50 mg TAE/g), flavonoid (18.10 mg QE/g), flavanol (17.70 mg CE/g), alkaloid (26.98 mg/g), tannin (4.03 mg/g) and saponin (3.69 mg/g). Antioxidant assays indicated that both fractions exhibited antioxidant activity that is comparable to ascorbic acid and rutin with nitric oxide having the highest scavenging potential of 98.97% inhibition. GC-MS analysis of the alkaloid and flavonoid fractions revealed the presence of 18 and 22 compounds respectively. The antioxidant activity of Kalanchoe pinnata may be attributed to 5-hydroxymethyl furfural and oleic acid detected in the alkaloid and flavonoid fractions respectively. Overall, the data generated form this study portrayed Kalanchoe pinnata as a potential antioxidant agent.
