The invention provides a freeze-dried powder of a reference sample of Sanhua decoction, a preparation method and a quality detection method thereof. The freeze-dried powder is prepared by optimizing the preparation method of the reference sample of Sanhua decoction, which is a modern process for the reference sample of classic famous recipes. parameters to facilitate its subsequent pilot test and industrial production. The quality of the lyophilized powder of the benchmark sample of Sanhua Decoction was detected by two technical means: thin-layer chromatography and high-phase liquid chromatography, and thin-layer chromatography was used to identify all medicinal materials in Fang. A separate TLC detection method is developed, and the detection of rhubarb is added, which is used for anti-counterfeiting of rhubarb medicinal materials, which is more intuitive and clearer than the existing technology. The total content of magnolol and honokiol was determined by high performance liquid chromatography, which provided a quantitative monitoring method. |
