Description
Technical field
The present invention relates to the quality determining methods of Chinese materia medica preparation, the in particular to quality determining method of Low Back Pain ball.
Background technique
Pain in the loins is common in a variety of diseases such as kidney trouble, rheumatism, lumbar muscle strain and wound, and Chinese medicine thinks mostly due to impression
Cold-dampness, the damp and hot, qi depression to blood stasis of impression, deficiency of the kidney is physically weak causes, so Chinese patent drugs for treatment pain in the loins, it is necessary to dialectical according to cause of disease difference
It selects.
Low Back Pain ball is made of southern rattan, psoralea corylifolia, teasel root, pink reineckea herb, radix achyranthis bidentatae, Chinese yam, and Fang Zhongnan rattan temperature leads to evacuate pathogenic wind, and detumescence stops
Bitterly strong waist and knee, tonifying kidney and strengthening yang is relieving cough and asthma, promoting blood circulation and stopping pain；Promoting the circulation of qi that psoralea corylifolia is supporing yang；Pink reineckea herb regulating blood condition removing toxic substances, evacuate pathogenic wind synthetism；It is continuous
Disconnected and radix achyranthis bidentatae nourishing liver and kidney, strengthening the bones and muscles, dispelling stasis of blood and stimulating the menstrual flow；Chinese yam tonifying spleen nourishing the stomach, engender liquid and benefic lung, kidney tonifying arresting seminal emission；All medicine compatibilities, gather altogether
The benefits of replenishing kidney, strengthening waist, the promoting flow of qi and blood circulation, removing blood stasis and acesodyne.It is mainly used for qi depression to blood stasis caused by treating traumatic injury and lumbar muscle strain etc.
The pain in the loins of card.
Existing Low Back Pain ball quality standard determines psoralen, Isopsoralen, asperosaponin VI, oleanolic acid
Property identify, and have psoralen, Isopsoralen assay, but existing detection method is complicated for operation, precision is not high, practical
Mistake, the controllability existing defects of control of product quality specificity are easy to appear in operating process, it is difficult to Accurate Determining Low Back Pain master
Want composition.
The present invention after study, increases the microscopical characters item of finished product preparation, respectively to Chinese yam in prescription, stir-baked SEMEN PSORALEAE with salt solution,
Teasel root and southern rattan have carried out the identification of microscopic features, it is ensured that containing the main component of major function in preparation, play curative effect.Also mention
Having gone out can be with Accurate Determining Low Back Pain ball to the related substance accurate discrimination method of progress and accurate content assaying method, this method
Quality, it is exclusive it is controllable, stablize, be easy, feasible.
