Extraction is the separation of medicinally active portions of plant tissues using selective solvents through standard procedures. Extraction is defined as the process in which the animal or plant tissues are treated with specific solvents whereby the medicinally active constituents are dissolved out, cell tissue and most of inactive or inert components remain or undissolved. In pharmacy, the solvent used for extraction purpose is known as menstruum and residue left after extracting the desired constituents is known as marc. Microwave assisted extraction is better method for extraction in terms of high yield and takes less time for extraction.
