摘要:
Camellia yungkianensis (RJC) is a special wild tea germplasm characterized with high polyphenol and theobromine and low caffeine contents. However, the bioactive properties of RJC-derived teas remain uncharacterized. This study characterizes the metabolomic profile and bioactivity of black tea (BT) and white tea (WT) from Camellia yungkianensis (RJC) compared to conventional teas using standardized processing and analytical methods. RJC-BT and RJC-WT exhibited distinct floral and fruity aroma profiles identified via sensory evaluation. A total of 833 non-volatile metabolites across 15 structur...
