Longdan Xiegan Pill is a commonly used effective Chinese patent medicine for clearing the liver and gallbladder and dampness and heat, and is made up of ten herbs, such as gentian. The chemical composition contained in this product is complex, and the color reaction is used to interfere with each other and it is difficult to identify. The Pharmacopoeia of the People’s Republic of China was published in 1985 (Part 1), and it was identified by microscopic examination. In order to control the quality, commissioned by the Pharmacopoeia Commission, a preliminary discussion was made on the chemical identification method of Longdan Xiegan Pill. This article according to the characteristics of the chemical properties of some active ingredients, use thin layer and test tube test method, in the presence of group medicine, identification of Angelica, gentian, Guan Mu Tong, Bupleurum.
