Abstract: Sweet potato leaves have been reported to content an appreciable amount of bioactive compounds. Over the years, phenolic including flavonoids are intensely studied for their physiological health benefits as functional foods. This study was aimed to reveal some physiological properties of sweet potato leaves. The leaves of locally grown three sweet potato genotypes used in this study were harvested six weeks after planting. The results showed methanol extract had 63-79 % DPPH radical scavenging activity 55-59 % inhibitory effect on amylase, 0.81-1.75 g GAE/100 g (dw) of total phenolic content, and 7.57-10.51mg QE/100 g (dw) of flavonoids.
