چکیده انگلیسی
The aim of this study was to quantify the contents of individual quercetin glycosides in red, yellow and chartreuse onion by High Performance Liquid Chromatography (HPLC) analysis. Acid hydrolysis of individual quercetin glycosides using 6Â M hydrochloric acid guided to identify and separate quercetin 7,4â²-diglucoside, quercetin 3-glucoside, quercetin 4â²-glucoside, and quercetin. The contents of total quercetin glycosides varied extensively among three varieties (ranged from 16.10 to 103.93Â mg/g DW). Quercetin was the predominant compound that accounted mean 32.21Â mg/g DW in red onion (43.6% of the total) and 127.92Â mg/g DW in chartreuse onion (78.3% of the total) followed by quercetin 3-glucoside (28.83 and 24.16Â mg/g DW) respectively. Quercetin 3-glucoside levels were much higher in yellow onion (43.85Â mg/g DW) followed by quercetin 30.08Â mg/g DW. Quercetin 4â²-glucoside documented the lowest amount that documented mean 2.4% of the total glycosides. The varied contents of glycosides present in the different onion varieties were significant.
