Goji berry: quality assessment and crop adaptation of plants cultivated in Tuscany (Italy) by combination of carotenoid and DNA analyses

In this study HPLC analysis for the evaluation of carotenoids and DNA barcoding are reported for three different samples of Lycium cultivated in Tuscany (Italy). These two analytical methods can represent integrative methods for quality control of goji, giving also crucial information on the plant adaptation to different environments. Hence, carotenoids represent the quality markers proposed by the monograph of the European Pharmacopoeia, while DNA barcoding can differentiate between species and populations and is useful for the detection of the homogeneity of the samples
