This project contains DNA barcode sequences (rbcL, matK, ITS/ITS2, H-psbA, L-F) from 2 Litsea Lam.species collected in Sichuan Province, China, for species identification. Targeted loci
This thesis, titled "Identification and Comparative Phytochemical Profiling of Litsea coreana var. bairongcha as a Novel Natural Caffeine-Free Beverage Resource", presents a comprehensive study of BRC, focusing on addressing the critical gap regarding species confusion between BRC and hawk tea.We employed morphological identification, DNA barcoding, HPLC, and GC-MS, among other methods, to investigate the taxonomic identity and flavor compounds of BRC. Key findings include: (1) BRC is taxonomically distinct from hawk tea and represents a new variety; (2) significant flavor differences exist between the two materials; and (3) BRC is rich in polyphenols and terpenoids.The novelty of this study lies in the unambiguous identification of BRC through combined morphological and molecular characterization, as well as the elucidation of its flavor profile using HPLC and GC-MS analyses. These results provide scientific data to support the exploration of alternative tea resources.This work is original, has not been published or submitted elsewhere, and all authors have approved the submission of this manuscript. We confirm that the manuscript complies with the journal's ethical guidelines, including proper citation of prior work, compliance with data disclosure requirements, and no conflicts of interest.
