Biochemical Studies on Moringa Oleifera Leaves Extract

Abstract

Phytochemical screening were determined in Moringa oleifera leaves. The total polyphenols and flavonoids contents of Moringa oleifera leaves have the highest of total polyphenols and flavonoids contents, which were 129.44mgGAE/g and 20.43mgGAE/g, respectively. Methanolic and aqueous extracts of plant leaves was antioxidant activity by used (FRAP, LPO, OH, DPPH and ABTS) The methanolic extract of Moringa oleifera leaves have the highest of reducing power which was ranged from 0.818 to 3.021 at the concentrations of 20 and 80 mg/ml, respectively. Also, by used (LPO, OH, DPPH and ABTS), were the highest antioxidants activity for methanolic extract respectively. Moreover, The methanolic extract of Moringa oleifera leaves produced the highest growth inhibition (20 and 17mm) for against Escherichia coli and Bacillus subtillis at 4mg/ml, respectively. While, the aqueous extracts highest growth inhibition (13mm) of against St.coccus aureus at 4mg/ml.
