Research progress of extraction and isolation of natural plant polysaccharides and their applications in skin care
Plant polysaccharides are natural polymers extracted from various parts of plants,which are composed of ten or more monosaccharide units connected with glycosidic bonds.In recent years,their applications in skin care have attracted more and more attention due to the rich biological activity,low cytotoxicity,safety,and being skin-friendly.The biological activities of polysaccharides closely correlate with their structure,and different techniques of extraction and purification could have influence on the structure of polysaccharides.Therefore,in this review,the relevant studies on plant polysaccharides in recent years have been summarized,including the extraction,isolation and purification processes of plant polysaccharides,and the applications in skin care such as moisturizing and hydrating,skin whitening and antioxidative,anti-inflammatory and antibacterial properties.This review can provide theoretical support for application of plant polysaccharides in the development of cosmetics.
