Comparison of the origin and phenolic contents ofLycium ruthenicumMurr. by high-performance liquid chromatography fingerprinting combined with quadrupole time-of-flight mass spectrometry and chemometrics

Abstract: The fruits of Lycium ruthenicum Murr. have long been used in folk medicine. Nevertheless, detailed information related to its phenolic composition and its quality control remains scarce. In this study, a simple and reproducible method, based on high-performance liquid chromatography combined with chemometrics, was developed to authenticate 18 samples of L. ruthenicum Murr. collected from different parts of China through fingerprint analysis. The main peaks were identified by quadrupole time-of-flight electrosp… Show more

“…Fourteen fatty acids were also detected and confidently identified using GC-FID/MS methods using known standards. Using UHPLC-QTOFMS methods, furthermore, about 30 plant secondary metabolites were detected, relatively quantified, and identified based on the literature data ,,,,, including polyphenolic acids, anthocyanins, flavonols, and phenolamides (Table S2). Among these, flavonols and anthocyanins were only tentatively assigned since they had the same ion in the positive mode mass spectra, including cyanidin and kaempferol ( m / z , 287.2556), petunidin and (iso) rhamnetin ( m / z , 303.0505), and delphinidin and quercetin ( m / z , 317.0661).…”

“…In the case of UHPLC–MS analysis, identification of metabolites was achieved by matching precursor and product ions together with isotope pattern with the publically accessible databases (metlin, ; HMDB, ) and literature. ,− The quantitative results were shown as peak area of a given metabolite per milligram fresh Lycium fruits as discussed previously and subjected to the Student’s t -test or nonparametric statistical analysis where appropriate using an in-house developed MATLAB script …”

“…Phenolic compounds are abundant secondary metabolites in the berries, leaves, and roots of L. barbarum [ 60 , 61 ]. Around 88 distinct phenolic compounds have been recognized, with flavonoids constituting the predominant category among the berries ( Table A1 , Appendix A ) [ 59 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ]. In various studies on goji berries, variable values have been obtained for different assays, such as total polyphenol content (TPC), total flavonoid content (TFC), and total carotenoid content (TCC).…”

“…Lycium barbarum L. berries, known as Goji berry or wolfberry, have been used therapeutically in traditional Chinese medicine (TCM) for centuries 1 . It contains many chemical constituents, including polysaccharides, 1 phenolic acids 2 and carotenoids 3 . And it has been widely used as nutraceutical foods or dietary supplements in East Asia, Europe and North America, especially in China, Korea and Japan 1,4,5 .…”
