A New Gallotannin from the Extractives of Camellia oleifera Fruit Shell

phytochemical study of the nut shell of Camellia oleifera Abel led to the isolation of a new gallotannin, three known hydrolyzable tannins (2, 4, and 5), and gallic acid (1). The structure of the isolated new gallotannin was unambiguously elucidated on the basis of comprehensive spectroscopic data.
