本文通过薄层层析法检查提取物的分解产物中有无靛蓝,判明市售菘蓝叶中含吲哚甙,板蓝根中则不含。用同法证实感冒退热冲剂中亦不含吲哚甙。并通过模拟感冒退热冲剂的制备表明,菘蓝叶中的吲哚甙在冲剂制备过程中与拳参中的鞣质类生成沉淀被过滤除去了。 In this paper, the indigo in the decomposition product of the extract was examined by thin layer chromatography, and the commercially available indigo leaves were found to contain indigo, whereas the isatis root was not included. Using the same method to confirm that the cold fever granules are also free of phlegm. The preparation of a simulated cooling anaphylaxis granule showed that the indole in the indigo leaves was removed by filtration during the preparation of the granules and the precipitation of tannins in the boxing ginseng.
