Camellia flava (Pitard) Sealy is one of the yellow camellia species belonging to the genus Camellia (family Theaceae), which is widely distributed in Vietnam. Phytochemical investigation of the ethyl acetate extract of C. flava flowers collected in Phu Tho province led to the identification of eight phenolic compounds, including 3,3',4'-tri-O-methyl ellagic acid (1), pinoresinol (2), quercetin (3), kaempferol (4), tyrosol (5), caffeic acid (6), protocatechuic acid (7), and gallic acid (8). The structures of the isolated compounds were determined by NMR and MS spectroscopic analyses and comparison with the reported data. This study represents the first report of compounds (1–8) from the flowers of C. flava.
