preparing permethyl derivatives of GAs and GA-glucosides is described using NaH and MeI in DMF. The permethyl derivatives of the glucosides give sharp GC peaks and their MS provide information for the identification of the GA and carbohydrate moieties. The detection and characterization of endogenous GAs and GA-glycosides in pods of Phaseolus coccineus by GC-MS of permethylated extracts are described
摘要 描述了在 DMF 中使用 NaH 和 MeI 制备 GAs 和 GA-葡萄糖苷的全甲基衍生物的简便方法。葡萄糖苷的全甲基衍生物产生尖锐的 GC 峰,它们的 MS 为鉴定 GA 和碳水化合物部分提供了信息。描述了通过全甲基化提取物的 GC-MS 检测和表征菜豆豆荚中的内源性 GA 和 GA-糖苷。描述了通过相同方法对碳水化合物、IAA、ABA 和细胞分裂素进行全甲基化。
