The Chemistry of Eremophila Species. IV. Some Flavonoid Constituents

Abstract

A pigment from Eremophila fraseri F. Muell. has been shown to be 5,3',5'-trihydroxy-3,6,7,4'-tetramethoxyflavone by degradation and synthesis of the 3',5'-dimethyl ether. Pinobanksin and galangin-3-methyl ether have been isolated from E. ramossissima and E. alternifolia.
