- Abstract
- Sweetpotato [Ipomoea batatas (L.) Lam] leaves
are excellent source of low molecular weight antioxidants
such as polyphenols, anthocyanins and carotenoids compared
to other leafy vegetables. Endogenous antioxidants in sweetpotato
help our bodies to prevent ageing, heart diseases and
cancer. In this study, to develop the proper cultivars for the
functional feed materials, we investigated the contents of
anthocyanin, β-carotene, and polyphenols as well as DPPH
radical scavenging activity in leaves of 14 different cultivars
at the time of the harvest. They showed a diverse antioxidation
activity. In DPPH radical scavenging activity, cultivars of
Nanjing 9, Yulmi and Shinzami showed higher activity,
whereas cv. Huiza 6 showed the lowest. Cultivars of Shinzami
and Shinhwangmi had the highest anthocyanin (3.5 mg/g fr
wt) and polyphenol (15.8 mg/g fr wt) content, respectively.
Interestingly, there was a high correlation between cultivars
with colorful pigments in storage roots and antioxidants
activity in leaves. These results suggest that sweetpotato
leaves with high antioxidant activity at harvest would be
suitable for functional feed materials.
