Abstract

The invention discloses a detection method of a Chinese herbal compound containing angelica sinensis. The method comprises the following steps: taking a Chinese herbal compound test sample and reference substances for detection, wherein the Chinese herbal compound comprises angelica sinensis, cassia twig, licorice, white peony root, ginger and jujube; the reference substances are gallic acid, paeoniflorin, ferulic acid, liquiritin, ammonium glycyrrhizinate and 6-gingerol; and the chromatographic conditions of the detection are as follows: a C18 chromatographic column is adopted, methanol or acetonitrile is used as a mobile phase A, an acid aqueous solution is used as a mobile phase B, and a gradient elution procedure includes that 5%-12% A for 0-20 min is performed; 12%-85% A for 20-90 min is performed; a flow velocity is 0.8-1.2 mL/min; a column temperature is 25-40 DEG C; and a detection wavelength is 210-330 nm; and obtaining component information or component and content information of the Chinese herbal compound according to a detection result. According to the invention, the chemical components of the Chinese herbal compound containing the angelica sinensis are comprehensively and systematically analyzed by applying a high performance liquid chromatography technology, and a theoretical basis is provided for deep research on quality control and a pharmacodynamic material basis.

Description

technical field [0001] The application relates to the technical field of quality identification of traditional Chinese medicines, in particular to a method for constructing fingerprints of Chinese medicine compound containing angelica and its application. Background technique [0002] With the rapid development of traditional Chinese medicine preparations in my country, the quality management of traditional Chinese medicine preparations has also received widespread attention, and its quality will directly affect the quality of medical care and the safety of patients. Factors affecting the quality of traditional Chinese medicine preparations mainly include: (1) the quality of the original medicinal materials. The medicine market often obtains a lot of economic benefits from shoddy products. In addition, the supply of wild medicinal materials in my country's medicinal materials market is relatively lacking, coupled with the country's restrictions on the collection of wild nat...
