Tea contains polyphenols and is one of the most popular beverages consumed worldwide. Because most tyrosinase inhibitors that regulate melanogenesis are phenol/catechol derivatives, this study investigated the inhibitory effects of Camellia sinensis water extracts (CSWEs), including black tea, green tea, and white tea extracts, on melanogenesis using immortalized melanocytes. CSWEs inhibited me...

The cyanoglycoside, prunasin, was isolated for the first time as an aroma precursor of benzaldehyde from fresh tea leaves (Camellia sinensis var. sinensis cv. Yabukita). Prunasin was readily hydrolyzed by a crude enzyme prepared from the fresh tea leaves to liberate benzaldehyde. The isomerization of prunasin under neutral conditions was also recognized.

The relative efficacy of infusion of black tea leaf, Camellia sinensis (Linn.) O. Kuntze, (Theaceae), and iron as freshly prepared aqueous solution of ferrous sulphate in reducing the cytotoxic effects of arsenic, was tested in bone marrow cells of laboratory bred Swiss albino mice. Ferrous sulphate and tea given alone did not induce chromosomal breakage to any appreciable extent. Tea decreased...
