Novel 4-(2-methylphenyl)-flavan, rhusjavanins A and B, from the roots of Rhus semialata.
In this study, two novel flavan derivatives, namely, rhusjavanins A and B, along with two known flavans 2,3-trans-3,4-trans-3,4,7,4'-tetrahydroxyflavan and 2,3-trans-3,4-cis-3,4,7,4'-tetrahydroxyflavan, have been isolated from the roots of Rhus javanica. The structures were elucidated on the basis of spectroscopic data.
