Rapid HPLC/DAD/MS method to determine phenolic acids, glycoalkaloids and anthocyanins in pigmented potatoes (Solanum tuberosum L.) and correlations with variety and geographical origin

In the present study a single procedure to simultaneously determine phenolic acids, anthocyanins and glycoalkaloids was applied in 13 cultivars all with pigmented peel. A single exhaustive extraction for the three classes of compounds and a single analytical HPLC method were proposed.
