Potential of antibacterial, antioxidant and antidiabetic properties in mango leaves (Mangifera indica L.) crude extract
This study investigated the effect of different percentage of methanol (50, 70 and 90%), extraction time (1,3 and 5 days) and temperature (30-70°C) on the antibacterial, antioxidant and antidiabetic activity of crude leave extract of Mangifera indica L. Antibacterial activity of plant extracts was d...

Antibacterial activity of plant extracts was determine by using the agar well diffusion while the antioxidant activity of the plant extract was examine by using quantitative DPPH radical scavenging assay test. On the other hand, the antidiabetic properties of plant extracts was determine by using the in vitro test, inhibition of the alpha amylase enzyme.
