| description | The assessment of secondary metabolites shows the availability of
steroids, terpenes, glycosides, saponins, tannins, flavonoids, alkaloids, and
carbohydrate in the extracts of the stem bark of Lannea humilis. Steroids and terpenes were available in the hexane,
ethyl acetate and methanol fraction, while tannins, flavonoids and alkaloids
were available in the ethyl acetate and methanol extract. Carbohydrate and
saponins were available just in the methanol division. The antioxidant activity
of these plant extracts demonstrated a dose-dependent increment. The ethyl
acetate extract displayed most noteworthy antioxidant activity of 98% at 240
µg/ml, followed by the hexane extract which had a percentage antioxidant
activity of 92 % at 240 µg/ml. The methanol extract demonstrated percentage
antioxidant activity of 71 % at 240 µg/ml. These results demonstrated that this
plant can be used as a good antioxidant. |
