was prepared so as to simulate conditions of their extraction pertaining to their use for cooking purposes. The extract was
prepared with 5 kg fresh leaves in distilled water at 40-60 曟 for 48 h. The process was repeated twice for complete
extraction. This aqueous extract was concentrated under reduced pressure and lyophilized to get a powder (yield
10.5% w/w). This powder was dissolved in distilled water and used for analyzing the antioxidant activity in vivo as well as
in vitro.
