Phytochemical Screening was done by the standard protocols described by Trease and Evans, [10] using different
plant extracts of Plectranthus amboinicus and Hemigraphis colorata for tannins (responsible for anti-oxidant
activity) and saponins, [9-11]. Saponins: About 0.2 g of the extracts was mixed well with 5 ml of distilled water
and was heated until it boiled. Presence of saponins was indicated by Frothing (appearance of creamy miss of small
bubbles). Tannins: Mixing of small quantity of extracts with water and heating on a water bath was carefully done.
The obtained mixture was filtered and ferric chloride was added to the filtrate. The presence of tannins is indicated
by a dark green solution.
