Most PRMTs methylate glycine- and arginine-rich patches within their substrates.

大多数PRMTs作用于底物中的赖氨酸和精氨酸的富集区。

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。

Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇（比如C≥ 2的醇）在无催化剂的条件下无法直接和镁进行反应，本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。
