Lycium chinense Mill. is an important medicinal and edible perennial plant that has been developed as a popular vegetable and healthcare tea in southern China in recent years. In this study, we evaluated the nutritional quality of 13 different geographical L. chinense populations through a common-garden experiment. There were significant differences (P<0.05) in active components and nutrient elements among the populations. Principal component and clustering analyses showed that populations in the central China showed better integrated quality than the other populations; populations in southern China also showed good prospects for further development, having special characteristics such as high contents of amino acids, total flavonoids, and chlorogenic acid. Moreover, all the populations had much higher contents than most vegetables of flavonoids and of the mineral elements Fe, Se, Mn, and K. These results provide important information required for the development of L. chinense germplasm resources and to ensure the sustainable utilization of L. chinense.
