The Effect of Nano Extract Formulation on Antioxidant Activity of 70% Ethanolic Extract of Purple Sweet Potato’s Leaves (Ipomoea batatas L.) Antin-3 Variety

Purple sweet potato leaves contain anthocyanins with high antioxidant activity but are rarely used. To increase the activity of a natural product, nanoparticle formulation in the extract can be used. It can increase the absorption of the product in the gastrointestinal tract. However, the formulation of natural ingredients used for antioxidants can affect their activity. This study aimed to determine the effect of the nano extract formulation on the antioxidant activity of the leaf extract of purple sweet potato (Ipomoea batatas L.) antin-3 variety. The ionic gelation method carried out the manufacture of nano extracts. Meanwhile, the determination of antioxidant levels was carried out by the DPPH method using spectrophotometry Vis. The formulation of nano extract of purple sweet potato leaf (Ipomoea batatas L.) antin-3 variety affects its antioxidant activity. Nanoparticle formulation in purple sweet potato leaf extract affected its antioxidant activity.
