Purple-skinned tubers comprise twice the focus of phenolic acids as white-skinned tubers. The focus of those acids was three to 4 occasions in purple-fleshed cultivars than that of white-fleshed varieties (14).
The prime phenolic acids are chlorogenic acid, protocatechuic acid, vanillic acid, and p-coumaric acid (14).
The coloured tubers have about 5.5 mg to 35 mg/100g of flavonoids (like anthocyanins). The predominant anthocyanins are petunidin, peonidin, cyanidin, pelargonidin, and malvidin (14), (15).
Different flavonoids embrace catechin, epicatechin, eriodictyol, kaempferol, and naringenin (14).
