Polysaccharides extracted from plants are of high value, because of their medicinal properties and industrial applications such as drug carriers, pharmaceutical coating, cosmetics, and food preservation coatings. Polysaccharides of different structural properties and monosaccharide composition can be extracted from plants. There are different extraction methods and purification processes, which yield polysaccharides that, varies in activity and physicochemical properties. This review paper focuses on steps related to extraction and purification of plant polysaccharides. Different methods of extraction like hot water assisted extraction, ultrasound assisted extraction, microwave-assisted extraction, enzyme assisted extraction, acid assisted extraction, alkali assisted extraction, supercritical fluid assisted extraction, aqueous two phase extraction, freeze thawing cold pressing, and
