Tris-1,3,5-triazine and 2,4,6-Tris-1,3,5-triazine were synthesized from 2,4,6-trichlloro-1,3,5-triazine, the water solution of methylamine and dimethylamine.The products were characteried by FT-IR and DSC.

以三聚氯氰、甲胺和二甲胺水溶液为原料，合成了2，4，6-三甲胺基-1，3，5-均三嗪和2，4，6-三二甲胺基-1，3，5-均三嗪HMM），并用FT-IR和DSC对其进行了表征。

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。
