in Vitro and in Vivo Evaluation of Antioxidant Activity
The present study was conducted to determine whether aerial parts of Trichosanthes cucumerina extracts can exert significant antioxidant activity. The antioxidant activity of a. hot water extract (HWE) and a. cold ethanolic extract (CEE) of T. cucumerina aerial parts was evaluated by assessing its (a) radical scavenging ability and prevention effect of lipid peroxidation in vitro, and (b) effects on lipid peroxidation and antioxidant enzyme activities, in vivo.

Evaluation of the In Vitro and In Vivo Antioxidant
In Vitro Antioxidant Activity. The in vitro antioxidant free radical scavenging activity of SP was determined by using ABTS radical cation decolourization assay . In this assay, 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) or ABTS (C 18 H 18 N 4 O 6 S 4) is converted to its radical cation. This radical cation is dark green in colour and absorbs light at 734 nm.
