A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

黄蜀葵总黄酮total of flavone Abelmoschl Manihot L。

According to our method, we can quantify the total amount of isoflavone more rapid and conventiently without preparing all 12 kinds of standards.In this study, acetyl- and malonyl- glycosides were converted to 7-O-glycosides by reacting with 1M methanolic sodium methylate at 60℃ for 20 min. Then, the solution was neutralized with 2.5N HCL and extracted for further 30 min at 60℃. Aglycones and 7-O-glycosides were then analysed by HPLC.

根据本研究，此方法系使用1.0 M sodium methylate在60℃下与样品中之acetylglycoside、malonylglycoside反应20分钟，将其转化为7-O-glycoside，反应完成后以2.5N盐酸水溶液中和，调整溶液为80%甲醇溶液并在60℃下继续萃取30分钟然后进行HPLC分析；由於仅需要分析两种形式的大豆异黄酮化合物（aglycones及7-O-glycosides），因此可以有效地缩短分析时间至30分钟以内。
