Identification and quantification of minerals and vitamins of purple sweet potato ( Ipomoea batatas) leave

Abstract

Abstract Purple sweet potato leaves are abundant in polyphenols, antisionins, flavonoids, and other nutrients that are higher than other varieties and green vegetables and are very good for health but reports on mineral and vitamin content are still very rare even in many places including Jayapura are less aware of the benefits and uses of these leaves, while around many are malnourished, especially in pregnancy. The purpose of this study, namely Identifying and measuring, and analyzing the mineral and vitamin content of purple sweet potato leaves. To extract Fe, Zn, Cu, and Mn using the ICP-MS method. K, Ca, Mg, and Na using the AAS method while P, B-Carotene, and Vitamin C using the Spectrophotometric method. The results of this study were Fe (22,014.5 µg/100g), Zn (1,999.9 µg/100g), Cu (5 µg/100g), Mn (3,902.6 µg/100g), K (1,786,556 µg/100g), Ca (258,824 µg/100g), Mg (164,839 µg/100g), Na (305,531µg/100g), P (98,278 µg/100g). Vitamin C (300.845 µg/100g), B.Carotene (585.829 µg/100g). This study concludes that the minerals and vitamins of Koya Koso Jayapura purple sweet potato leaves are proven to be very high, and can be used as additional food and treatment for micronutrient deficiencies, especially for pregnant women. Suggestions for future researchers to identify more minerals and vitamins in these purple sweet potato leaves.
