Yellow needle crystals, m.p. 118.5°, were obtained in 0.25% yield from the root of Eupatrium japonicum THUNB. This substance indicated bright green coloration with ferric chloride, negative flavone and Fehling reactions. It possesses a conjugated double bond and a carbonyl group, and isopropenyl group was found from its infrared spectrum. Its properties agreed entirely with those of euparin and they were assumed to be identical, although no direct comparison was made.
