Banana (Musa paradisiaca) peels were collected and washed
thoroughly. They were boiled in distilled water at 90 ◦C for 30 min.
The boiled banana peels (100 g) were crushed in 100 ml distilled
water and the resultant extract was filtered through a clean muslin
cloth. The filtrate was precipitated with equal volumes of chilled
acetone. The resulting precipitate was collected by centrifugation
at 1000rpm for 5min, air-dried into a powdered form and used for
further experiments.
