鹤草芽为 Agrimonia pilosa Ledeb.的带短小根茎的芽,有驱绦虫的作用,有效成分为鹤草酚,是一种新的双环酰基间苯三酚类衍生物。基于三氯化铁与酚羟基的反应,可在含三氯化铁的薄层板上层析后,直接用扫描法定量。此法简便、快速,适用于测定各采收期及不同部位鹤草芽中鹤草酚的含量。仪器及药品1.岛津双波长扫描仪 CS-900。2.含三氯化铁的硅胶 G 薄层:取硅胶(青岛海洋化工厂出品,经盐酸处理)4.5g 与煅石膏0.5g 混合,
The crane grass bud is a short rhizome bud of Agrimonia pilosa Ledeb. It has the function of driving aphids, and the active ingredient is repens, which is a new bicyclic acylphloroglucinol derivative. Based on the reaction of ferric chloride with phenolic hydroxyl groups, it can be directly quantified by scanning after chromatography on thin plates containing ferric chloride. This method is simple and rapid, and is suitable for determining the content of the reniformin in the harvested cranegrass buds at different harvesting periods and at different parts.
