GALLOCATECHIN, or 5'-hydroxycatechin, was first isolated from Japanese green tea by Tsujimura¹ in 1934, and later shown by Bradfield and Bate-Smith² to be l-epigallocatechin. d-Gallocatechin was obtained by Oshima (Osima)³ in 1939 from the bark of Formosan Casuarina equisetifolia and termed 'casuarin'.
