Maximum gallic acid (standard phenolics) was observed from microwave assisted extract of Tapal Tez dam. Stove extracts produced maximum phenolics from Lipton tea. Maximum catechin (Standard of flavonoids) was observed from microwave assisted extract of Johar Joshanda while stove extracts produced maximum catechin from Coffee sample.
