Degradation of the components of Leonurus Herb was examined during drying. Compounds 1 and 2 were detected on TLC at lower temperature, but not at higher temperature. Their chemical structures were determined by spectral methods. They immediately decomposed even at 40°C in chloroform solution. They are believed to be transformed through a retro-aldol reaction. Compounds 1 and 2 have not been previously reported.
在干燥过程中对益母草的成分降解情况进行了研究。化合物1和2在较低温度下可通过薄层色谱法检测到,但在较高温度下则检测不到。它们的化学结构通过光谱方法确定。即使在40°C的氯仿溶液中,它们也会立即分解。据信它们是通过逆羟醛反应转化的。化合物1和2此前未见报道。
