Biphenyl esters and biflavonoids from the fruits of Schinus terebenthefolus

Two new biphenyl esters and three biflavonoids were isolated from the aqueous methanol extract of the fruits of Schinus terebenthefolus. The spectral data of tetrahydrorobustaflavone have been recorded and assigned for the first time. Characterization of the structures was achieved by various spectroscopic methods.
