BACKGROUND
The potential of 1-methylcyclopropene (1-MCP) to maintain postharvest storage of sweet potato was studied. In two separate experiments, the orange-fleshed sweet potato cv. Covington was treated with 1-MCP (1.0 µL L-1 , 24 h) and roots stored at 15 °C. During storage, samples were
Marked polyphenol production takes place in root tissue of sweet potato, Ipomoea batatas Lam. cv. Norin 1, in response to slicing. A possible intermediate, tentatively termed compound V, of chlorogenic acid biosynthesis was isolated from the root tissue administrated with t-cinnamic acid-2-(14)C.
The active turnover of chlorogenic acid (3-caffeoylquinic acid(3)), a major phenolic component of Xanthium leaves and potato tuber disks, has been demonstrated in these tissues. Pulse-labelling experiments with radioactive l-phenylalanine and trans-cinnamic acid as well as direct feeding experiments
Polyphenolic phytochemicals present in fruits and vegetables indisputably confer anticancer benefits upon regular consumption. Recently, we demonstrated the growth-inhibitory and apoptosis-inducing properties of polyphenol-rich sweet potato greens extract (SPGE) in cell culture and in vivo prostate
The antioxidative activity of a 70% methanol extract of sweet potatoes was estimated in a linoleic acid-aqueous system. The extract had a markedly strong antioxidative activity. Major phenolic components contained in the 70% methanol extract were identified as chlorogenic acid and isochlorogenic
BACKGROUND
In a previous study, anthocyanin levels in potato plants were increased by manipulating genes connected with the flavonoid biosynthesis pathway. However, starch content and tuber yield were dramatically reduced in the transgenic plants, which over-expressed dihydroflavonol reductase
Simon extracts are vitamin K(1)-rich food materials extracted from the leaves of the Simon sweet potato. Although vitamin K is known to stimulate bone formation, we postulated that Simon extracts also contain unknown biological compounds having the ability to regulate bone resorption. Here we
