[Use of the HPLC method for determination of glucopiranosides during ripening of faba bean seeds].


PMID 9064746

Abstract

Uridine (C9H12N2O6) was applied as an internal standard for the determination of glucopiranosides in faba bean seeds by the HPLC method. The relative UV response factors of vaccine or convicine to uridine were determined (1.12 and 0.79, respectively). The changes in the content of vaccine and convicine during ripening of faba bean seeds were followed. It was observed that with the increase in the seed dry matter content from 0.18 kg/kg to 0.78 kg/kg, the dry matter based content of vaccine decreased from 26.225 g/kg to 0.243 g/kg, and that of convicine from 9.051 g/kg to 0.094 g/kg.
