ABSTRACT
 
Microwave assisted extraction is a modern and novel approach for rapid and efficient extraction of the plant material which is of prime importance in herbal medicinal industry. For household herbal products (different tea samples, qehwa (Peshawari Qehwa), coffee (Nescafe Classic) and joshanda (Qarshi), their qualitative and quantitative analysis of phytochemicals were compared. Microwave assisted extraction gave the maximum amount of extracts than that of stove heating with significant difference of amount of phenolics and flavonoids. 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.
Keywords: Microwave assisted extraction, stove heating, herbal products, phenolics
