Abstract

A simple and efficient method is described for separation and determination of ascorbigen in Brassica vegetables by overpressured-layer chromatography. Natural ascorbigen was identified from chromatographic retention, UV spectral, and mass spectrometric data using the authentic substance for comparison. Quantification of ascorbigen revealed significant differences (4.52-26.81 mg kg-1) among the species studied. The highest level of endogenous ascorbigen was observed in the sample prepared from broccoli (26.81 mg kg-1).
