ANTHOCYANINS FROM INDIAN CASSAVA (MANIHOT ESCULENTA CRANTZ) AND ITS ANTIOXIDANT PROPERTIESAbstract
Cassava ((Manihot esculenta Crantz) leaf stalk is a renewable raw material and it is a major industrial crop in Tamilnadu rich in antioxidant compounds. To utilize this source, an environmentally sustainable procedure has been developed for the extraction of anthocyanin and to analyze its antioxidant properties. So, the present research was focused on cassava for total phenol contents, flavanoids, anthocyanins and it’s antioxidant activities were studied using leaf stalks. Three difficult solvents were tried to extract total phenol and anthocyanin from cassava leaf stalks. In the case of total phenol content acetone extract found to have maximum phenol content followed with acidified methanol and methanol. In the case of anthocyanin content, acidified methanol extract gave maximum yield followed with methanol and acetone extracts. The presence of phenolic compound and anthocyanin determine the free radical scavenging activity in cassava leaf stalk extract. The cassava leaf stalks, which was found to be a waste material after harvesting the tubers can be used as a valuable source for anthocyanin extraction, which will applicable in clinical and food industry.
