EXTRACTION HYALURONIC ACID FROM SOME PLANT SOURCES AND STUDY ITS ANTIOXIDANT ACTIVITY

Abstract

Hyaluronic acid, which is one of the many carbohydrates that has unique physical and chemical properties, is one of the important natural polymers, which made it widely used in the fields of pharmaceuticals, biomedical, nutritional and cosmetic supplements. Hyaluronic acid is composed of repeating units of glucuronic acid and N-acetyl glucosamine. Plants are among the important sources for the extraction and production of many effective compounds of nutritional importance and medical, pharmaceutical and cosmetic applications, due to its features, including low production cost, safe in terms of use and rich in natural antioxidants. In this study, light was shed on some plant sources such as sweet potatoes and local potatoes, as well as some plant residues such as lettuce leaves, which are rich in hyaluronic acid, and the modern techniques used in its extraction and displaying its biological properties and antioxidant effectiveness. Acid extracted by FTIR and high performance liquid chromatography (HPLC). The antioxidant activity of extracted hyaluronic acid was also tested. The acid extracted from sweet potato crests had higher antioxidant properties compared to the acid extracted from local potatoes and lettuce leaves
