Abstract:
:The chemical investigation of leaves of Bridelia glauca f. balansae afforded six megastigmane glucosides, named bridelionosides A-F, along with seven known megastigmane glucosides. Their structures were determined by a combination of spectroscopic analyses and by application of the modified Mosher's method.
