中文摘要 | 從白皮甘藷中,運用傳統濾紙層析和高效率液相層析 (HPLC) 分離並純化四種含醯花色素?。利用 HPLC 和纖維素薄層層析 (Cellulose TLC) 方法,色素中的花色素和醯基分別被鑑定為 cyanidin 和 caffeic acid 和 ferulic acido 利用氣液相層析 (GLC) 方法,花色素?中的糖部份被鑑定為葡萄糖。快速原子撞擊游離法質譜儀 (FA-mass) 應用於測定這些色素的去醯花色素?的分子量。利用 HPLC 和β-glucosidase 水解反應,C-3位置糖被鑑定為 Sophorosc。使用層析法,紫外光──可視光光譜分析和化學分析法,這四種含醯花色素?初步被定性為:caffeoyl Cyanidin 3-sophoroside 5-glucoside、diCa-ffeoyl cyanidin 3-sophoroside 5-glucoside、direruloyl cyanidin 3-sophoroside 5-glucoside 和 cafieoyl cyanidin 3-sophoroside 5-glucoside。 |
英文摘要 | Four major acylated anthocyanin pigments of white skin sweet potato roots (Ipomoea batatas) were isolated and purified by HPLC and conventional paper chromatographic methods. Aglycones and acyl moieties of these pigments were identified to be cyanidin, and caffeic and ferulic acid by cellulose TLC and HPLC. The sugar moieties were identified to be glucose by GLC. Molecular weights of their deacylated anthocyanins were measured by FAB-mass. C-3 sugars were identified to be sophorose by HPLC and β-glucosidase digestion. By chromatographic method, UV-visible spectrometry and chemical analysis, these pigments were tentatively characterized as caffeoyl cyanidin 3-sophoroside 5-glucoside, dicaffeoyl cyanidin 3-sophoroside 5-glucoside, diferuloyl cyaniding 3-sophoroside 5-glucoside and caffeoyl cyanidin 3-sophoroside 5-glucoside. |
