Abstract

The invention discloses a quality control method for mulberry chrysanthemum granules. The method comprises a step of measuring rosmarinic acid characteristic component content of self-heal by adopting high performance liquid chromatography. The established thin-layer chromatography and high performance liquid chromatography method is simple and convenient and has good practicability; an established fingerprint map for the mulberry chrysanthemum granules is favorable for comprehensively grasping the quality of the mulberry chrysanthemum granules; and meanwhile, the method identifies the main chromatographic peak, makes up the fuzziness of the fingerprint map of the mulberry chrysanthemum granules, jointly forms a quality standard system of the mulberry chrysanthemum granules, and fulfills the purpose of effectively controlling the quality of the mulberry chrysanthemum granules.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and in particular relates to a quality control method for Xiasangju granules. Background technique [0002] Xiasangju granule is a characteristic drug in Lingnan area, which is made of selected Prunella vulgaris, mulberry leaves, and wild chrysanthemums, and is refined and processed by modern technology. The 11th category of traditional Chinese medicine, has the effects of clearing the liver and improving eyesight, dispelling wind and heat dissipation, dehumidifying numbness, and relieving sores. It is suitable for treating red eyes, headaches, high blood pressure, dizziness and tinnitus, sore throat, and boils caused by wind-heat and cold. Symptoms of poisoning. [0003] At present, there are 105 domestic and foreign enterprises producing Xiasangju granules. However, in terms of quality standard research, it mainly focuses on qualitative identification. For example, in the "Drug St...
