[0002] Shandougen is the dry root and rhizome of Sophora japonica, a leguminous plant. It has the effects of clearing away heat and detoxification, reducing swelling and relieving throat. It contains matrine, oxymatrine, sophocarpine, dauricine, genistein, β- Sterols, flavonoids and other components, the current "Chinese Pharmacopoeia" has a relatively simple quality control method for the root of the mountain bean root, and only uses the content of matrine and oxymatrine as the quality evaluation index of medicinal materials, but Commonly found in leguminous plants Alopecia sophora, Sophora flavescens, Sophora japonica, Sophora japonica, etc., but not the specific components of Sophora japonica root, it is difficult to measure the content of matrine and oxymatrine to reflect the quality of medicinal materials as a whole

Abstract

The invention discloses a method for identifying the authenticity of subprostrate sophora. The authenticity of a sample of the subprostrate sophora medicinal material is judged by measuring the content of phenylbenzofuran in the sample of the subprostrate sophora medicinal material. The detection method provided by the invention is accurate and reliable, the interference of other impurities in thesample can be effectively eliminated, a satisfactory separation detection effect can be obtained, and the method is simple and convenient to operate, feasible, low in cost and high in practicability,thereby being very suitable for product quality detection.

Description

technical field [0001] The invention relates to the field of identification methods of Chinese medicinal materials. More specifically, the present invention relates to a method for identifying the authenticity of the mountain bean root. Background technique [0002] Shandougen is the dried root and rhizome of Sophora japonica, a leguminous plant. It has the effects of clearing away heat and detoxifying, reducing swelling and relieving throat. It contains matrine, oxymatrine, sophocarpine, dauricine, genistein, β- Sterols, flavonoids and other ingredients, the current "Chinese Pharmacopoeia" has a relatively simple quality control method for the root of the mountain bean root, and only uses the content of matrine and oxymatrine as the quality evaluation index of medicinal materials, but It is commonly found in leguminous plants Alopecia sophorae, Sophora flavescens, Sophora japonica, Sophora japonica, etc., but not the specific components of the root of the mountain bean roo...
