本文对板蓝根冲剂以及原料板蓝根、大青叶中氨基酸、靛玉红、吲哚甙等主要化学成分进行了鉴别试验,拟订了冲剂中氨基酸、靛玉红的薄层鉴别方法,并且对含量测定方法进行了摸索,初步拟定以总氮量作为板蓝根冲剂的质量控制指标。
In this paper, the main chemical constituents of Banlangen granules, raw materials Banlangen, Daqingye, amino acid, indirubin, and indole were identified and identified. A thin layer identification method for amino acids and indirubin in granules was developed, and the determination method was determined. The exploration was carried out and the total nitrogen was taken as the quality control index of Banlangen granules.
