Abstract

Sweet potato greens or leaves are commonly consumed by rural people in some part of Indonesia, Malaysia, The Philippines, and other part of the world. In addition to their nutritive value, sweet potato leaves have been reported to content an appreciable amount of bioactive compounds such as polyphenol including flavonoids beneficial for health. Over the years, phenolic including flavonoids are intensely studied for their physiological health benefits as functional foods. However information on bioactive contents of sweet potato greens grown locally in Lampung are inexistent, therefore this paper reports some components believed to be potential for human health. The leaves of locally grown three sweet potato genotypes used in this study were harvested six weeks after planting. The results showed methanol extract of sweet potato leaves had 63-79% DPPH radical scavenging activity 55-59 % inhibitory effect on a amylase , 0.81-1.75 g GAE/100 g dry weight of total phenolic content, and 7.57-10.51mg QE/100 g dry weight of flavonoids.
