Six flavonoids were isolated from Brickellia arguta and identified using chemical and spectral methods.

Three of these flavonoids were tested and showed inhibition of rat lens aldose reductase.

In a continuation of a phytochemical investigation of the genus Brickellia (Tribe Eupatorieae, Subtribe Alomiinae, Family Compositae) (1-6), we now report the isolation and characterization
