[Studies on the chemical constituents from the aerial parts of Breynia fruticosa].

Objective: To investigate the chemical constituents from the aerial parts of Breynia fruticosa.

Method: Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical evidence and spectral methods.

Result: Seven compounds were obtained and identified by spectroscopic methods and compared with authentic samples as aviculin [(+)-isolariciresinol-9'-rhamno-pyranoside], friedelan-3beta-ol, friedelin, arborinone, isoarborinol, 5-hydroxy-7,8,4'-trimethoxy flavone, 2,4-dihydroxy-6-methoxy-3-methyl-acetophenone.

Conclusion: All compounds were firstly isolated from B. genus, furthermore, aviculin was isolated from Euphorbiaceae for the first time.
