Problems solved by technology

[0004] However, the above-mentioned reports are all based on the fingerprints of lotus leaf medicinal materials and formula granules, and the detection methods are different. Therefore, it is difficult to effectively compare and analyze the differences in the characteristic maps of lotus leaf medicinal materials, decoction pieces, standard decoctions, and formula granules. It is difficult to deeply understand the transfer of lotus leaf medicinal material basis in the technological process from medicinal materials to formula granules, and it is difficult to overall evaluate and control the technological process from lotus leaf medicinal materials to finished lotus leaf formula granules

Description

technical field [0001] The invention specifically relates to an HPLC detection method for characteristic maps of lotus leaf medicinal materials, decoction pieces, standard decoctions and formula granules. Background technique [0002] The lotus leaf is the dried leaf of Nelumbo nucifera Gaertn., a plant of the water lily family. It was first recorded in "Diet Therapy Materia Medica". , Diarrhea due to spleen deficiency, spit mandrill due to blood heat, bloody stool and metrorrhagia, are commonly used clinical traditional Chinese medicine varieties. The lotus leaf mainly contains various alkaloid components such as nuciferine, protonuciferine, and pronuciferine, as well as flavonoids such as quercetin. Modern studies have shown that alkaloids in lotus leaves have pharmacological activities such as lipid-lowering, weight loss, antibacterial, and antiviral. The overall composition and content of these chemical components are the basis for the clinical efficacy of lotus leaf. ...
