Macamides, functional compounds found only in Lepidium meyenii Walpers, have gained interest in many fields of research due to its multiple bioactivities. Nevertheless, the mechanism by which macamides are synthesised is not thoroughly understood. In this study, the synthesis of six macamides and the conversion of three glucosinolates were studied systematically during a 6‐month natural air drying process. An investigation of synthesis profiles showed that the largest category of macamides, the major constituents of total macamides, has the same benzyl group as benzyl glucosinolate, which has higher content than other glucosinolates. The second largest group of macamides contains the same m‐methoxybenzyl group as m‐methoxybenzyl glucosinolate which is the second major constituent of total glucosinolates. The results from this study suggest that glucosinolates are one of the most important precursors of macamides. Compared with all other drying methods, natural air drying is the most suitable condition for the formation of macamides.

在自然空气干燥过程中，甲酰胺的代谢形成特征伴随着芥子油中芥子油苷的转化

Macamides，功能性化合物，发现只有在玛咖Walpers，已经获得了许多研究领域的兴趣，因为它的生物活性多。然而，尚未完全了解合成酰胺的机理。在这项研究中，在6个月的自然风干过程中，系统地研究了6种酰胺的合成和3种芥子油苷的转化。对合成图谱的研究表明，最大类别的氨基甲酰胺是总氨基甲酰胺的主要组成部分，具有与芥子油苷苄基酯相同的苄基，后者的含量高于其他芥子油苷。macamides的第二大组包含相同米甲氧基苄基作为米-芥子油苷的甲氧基苄基，是总芥子油苷的第二大主要成分。这项研究的结果表明，芥子油苷是macamides最重要的前体之一。与所有其他干燥方法相比，自然空气干燥是形成酰胺的最合适条件。
