Other claims from this paper (6)
- Association Purple and red potato cultivars had higher total phenolic and anthocyanin levels than tubers of other flesh colours.
- Observation Anthocyanins are noncompetitive inhibitors of the three enzymes.
- Observation Phenolic acids are mixed inhibitors of alpha-amylase and alpha-glucosidase.
- Observation Phenolic acids are noncompetitive inhibitors of aldose reductase.
- Observation Chlorogenic acid is the predominant phenolic acid in the potato cultivars.
- Observation The major anthocyanin consists of petunidin, peonidin, malvidin and pelargonidin derivatives.
