The methanol extract of the dried stem bark of Drypetes armoracia Pax & Hoffm. afforded two compounds named drypearmoracein A, (E)-4,5,6,7-tetrahydroxy-2-benzylhept-2-enoic acid and drypearmoracein B, 2,3-dihydroxy-9,10-tetrahydroanthra-1,4-quinone along with five known compounds: friedelan-3 β-ol, friedelin, friedelane-3,7-dione, drypemolundein B and β-stigmasterol. Their structures were established on the basis of spectroscopic analysis and chemical evidence. Two compounds named drypearmoraceins A and B have been isolated from Drypetes armoracia.
