Untargeted metabolomics reveals enhanced antioxidant capacity and key bioactive components of Gougunao No. 2 black tea
Under the tested conditions, cultivar background is associated with coordinated amino-acid- and phenolic/flavonoid-related metabolic differences and with assay-specific antioxidant indices, suggesting that integrated metabolomics-antioxidant profiling may be useful for quality-oriented cultivar evaluation within the scope of this two-cultivar study.
