Abstract

Sweet potato leaves, which are the byproducts of sweet potato cultivation, are reported to contain many bioactive components that have potential health benefits. However, the leaf morphology varies greatly. This morphological difference affects the level of acceptance for consumption. Therefore the aim of this research is to identify: (1) Sweet potato leaves clones that are most preferred by consumers; (2) Antioxidant activity of sweet potato leaves of various clones. This research was comducted in Completely Randomized Design (CRD) with three replications. The treatments were consisted of the leaf of Ayamurasaki clone of sweet potato, LPG-21, LPG-01, LPG-02, LPG-11 and LPG-15. The observed parameters were sensory properties and antioxidant activity test performed with DPPH and FRAP assays. The results showed that; (1) The leaf of sweet potato plant of clone LPG-01 has the highest color score of 3.23 (moderately liked), aroma score of 3.23 (moderately liked), taste score of 3.03 (moderately liked), texture score of 3.43 (moderately liked), mastication score of 3.07 (moderately liked) aftertaste score of 3.13 (moderately liked); (2) The antioxidant activity test showed that the leaf of LPG-01 clone of sweet potato has the highest score in DPPH method with the antioxidant activity percentage of 81.77%, and IC50 value 132,83 µg/ mL while in FRAP method with FRAP value of 50.56 mg AAE/g of extract
