The aim of this study was to investigate the effect of cold storage of Chinese cabbage on the content of glucosinolates (GSLs). High performance liquid chromatography (HPLC) separation method guided to identify and quantify eleven GSLs including six aliphatic (progoitrin, sinigrin, gluconapoleiferin, gluconapin, glucocochlearin and glucobrassicanapin), four indolyl (4-hydroxyglucobrassicin, glucobrassicin, 4-methoxyglucobrassicin and neoglucobrasscin) and one aromatic (gluconasturtiin) respectively. Storage at 4 °C for 72 h, the content of total GSLs were gradually decreased from 13.1 to 7.41 μmol/g dry weight (DW), whereas, approximately 63 and 55% content of aliphatic and indolyl GSLs were reduced. This finding suggests that the nutritional contents of Chinese cabbage, especially GLSs could not be preserved for a long time in the cold storage condition.

Abstract


The aim of this study was to investigate the effect of cold storage of Chinese cabbage on the content of glucosinolates (GSLs). High performance liquid chromatography (HPLC) separation method guided to identify and quantify eleven GSLs including six aliphatic (progoitrin, sinigrin, gluconapoleiferin, gluconapin, glucocochlearin and glucobrassicanapin), four indolyl (4-hydroxyglucobrassicin, glucobrassicin, 4-methoxyglucobrassicin and neoglucobrasscin) and one aromatic (gluconasturtiin) respectively. Storage at 4 °C for 72 h, the content of total GSLs were gradually decreased from 13.1 to 7.41 μmol/g dry weight (DW), whereas, approximately 63 and 55% content of aliphatic and indolyl GSLs were reduced. This finding suggests that the nutritional contents of Chinese cabbage, especially GLSs could not be preserved for a long time in the cold storage condition.
