Problems solved by technology

[0003] The quality inspection standard of Yuanwei'an Capsules is relatively backward. Only the quality inspection of some active substances of Panax notoginseng, artificial bezoar and astragalus is carried out, and the quality cannot be comprehensively detected; the invention provides a high-efficiency , accurate identification and content determination methods

Abstract

The invention discloses a quality detection method for a weinai'an tablet. The quality detection method adopts one or more of the following identification and content determination items: thin-layer identification of radix astragali; thin-layer identification of radix astragali, red ginseng and pseudo-ginseng; thin-layer identification of atificial cow-bezoar; high performance liquid chromatography qualitative and quantitative identification method of weinai'an tablet; and high performance liquid chromatography quantitative identification method of Astragaloside IV. The method provided by the invention improves and revises the original weinai'an capsule quality standards, revises and enlarges thin-layer identification of radix astragali's four flavonoid components and Astragaloside IV, simultaneously revises and enlarges thin-layer identification of red ginseng, and identifies the index components Astragaloside IV, ginsenoside Rg1, Rb1 and notoginsenoside R1 at the same time. The method employs an HPLC-PDA-ELSD combined technology to establish a main active ingredient content determination and characteristic spectrum to realize effective control of the weinai'an tablet quality. At the same time, the method has the advantages of high efficiency, accurate quantification, good stability, high precision and excellent repeatability.

Description

Technical field [0001] The invention relates to a quality detection method of Weinaian tablets. Background technique [0002] Weinaian capsules are mainly composed of astragalus, panax notoginseng, red ginseng, nacre powder, artificial bezoar, etc. It has the functions of invigorating qi and spleen, promoting blood circulation and relieving pain. It is used for stomach pain caused by spleen and stomach qi deficiency and congestion. Abdominal pain or tingling, poor appetite; chronic gastritis, gastric and duodenal ulcers with the above symptoms, the quality standard is now included in the 2010 edition of the Chinese Pharmacopoeia, Chinese patent number ZL200510037077.7, invention The invention patent entitled "A Chinese patent medicine for treating peptic ulcer and its preparation method" discloses its composition and its preparation method. On the basis of keeping the original formula of Wei Nai'an capsule unchanged, guided by the theory of Chinese medicine, based on clinical cu...
