d-Gallocatechin from the Bark of Casuarina equisetifolia Linn.

Abstract

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’.
