Radix isatidis particle quality control method

Abstract

The invention provides a radix isatidis particle quality control method and aims to measure arginine content and indirubin content at the same time by an HPLC (high-performance liquid chromatography). The radix isatidis particle quality control method comprises the following steps of respectively preparing an arginine standard sample, an indirubin standard sample and a radix isatidis particle test sample; performing comparison calculation to obtain the arginine content and the indirubin content of the radix isatidis particle test sample by the HPLC. The control method for the radix isatidis particle content is easy to operate; a quantification control requirement on effective components in a traditional Chinese medicinal product in which the type of the effective component is complicated is met, so that the quality level of the product is improved; the practice shows that the arginine content of radix isatidis particles is limited to be more than or equal to 12.5 mg/g in each gram of particles and the indirubin content of the radix isatidis particles is limited to be 0.12 mg/g, and the arginine content and the indirubin content which are limited can be used as quality control standards on the radix isatidis particles.

Description

technical field [0001] The invention relates to a method for controlling the quality of Banqing granules, in particular to a method for realizing the quality control of Banqing granules by measuring the content of arginine and indirubin in the Banqing granules. Background technique [0002] Banqing granule is a common veterinary prescription. The prescription contains Radix Isatidis and Folium Folium. It has the functions of clearing heat and detoxifying, reducing swelling and stagnation, strengthening the heart, diuresis and gallbladder, antibacterial and anti-inflammatory, antiviral, and enhancing immunity. It is mainly used to prevent and treat porcine influenza, high fever, reproductive and respiratory syndrome, parvovirus disease, hemorrhagic sepsis, erysipelas, streptococcal disease, paratyphoid fever, viral enteritis, eperythrozoonosis, pseudorabies, and piglet weaning Systemic failure syndrome and other immunosuppressive diseases. In addition, it also has a good cura...

AI Technical Summary

Problems solved by technology

[0004] Banqing granule is a veterinary compound traditional Chinese medicine containing multiple components and complex components. Due to the complexity of the components, the content is difficult to control, which affects the safety and effectiveness of traditional Chinese medicine. If the quality control of the active ingredients cannot be carried out, it is difficult to guarantee the quality of the veterinary compound traditional Chinese medicine.
