[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.
