Quality Evaluation of Thirteen Geographical Populations of Lycium chinense Using Quantitative Analysis of Nutrients and Bioactive Components

Abstract: 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 Ch… Show more

“…The total sugar content was determined using a titration method, 22 with a few modifications. For this, 2.0 g of goji berries samples and 200 mL water were placed into a 250‐mL volumetric flask and extracted for 30 min at 80 °C.…”

“…The phenol–sulphuric acid method was used to analyze polysaccharide content as described previously with minor modifications [ 23 ]. Approximately 2 g of dried pseudobulb powder was treated with 50 mL H 2 O for 120 min at 100 °C twice using the conventional heating reflux extraction method.…”

“…Common garden experiments retaining the same cultural environment can be used to analyze phenotypic variation among different populations to eliminate phenotypic variation induced by environmental factors and have become an important means of resource evaluation [ 20 22 ]. Through the collection of wild resources for common garden cultivation, quality evaluation was performed to determine the high-quality resources in the tested varieties and has been widely used in many medicinal plants, such as Epimedium sagittatum and Lycium chinense [ 22 , 23 ]. Gray relation analysis (GRA) is a multifactor statistical analysis method that includes dimensionless processing, correlation coefficient calculation, correlation degree and relative correlation degree calculation and is widely used in the comprehensive evaluation of the quality of medicinal materials [ 24 ].…”
