Abstract

The invention discloses a method for detecting active ingredient content in Yushangling Capsule, including the following steps: (1) reference substance solution is prepared; (2) testing substance solution is prepared; (3) standard curve is drawn; (4) the active ingredient content in Yushangling Capsule is measured. The invention screens the active ingredient content in Yushangling Capsule through lots of experiments; moreover, the invention screens the method for extracting bergenin from made medicine of Yushangling Capsule and ensures that the bergenin is suitable for high efficient liquid phase chromatogram detection after technical treatment; meanwhile, conditions for chromatogram detection are established. The method can effectively detect the active ingredient content in Yushangling Capsule and can effectively control product quality to ensure curative effect of product; therefore, the method can be widely used in production control in pharmaceutical factory.

Description

technical field [0001] The invention relates to a modernized quality control method of traditional Chinese medicine, in particular to a method for detecting the content of active ingredients in Yushangling capsules. Background technique [0002] Yushangling Capsule is a traditional Chinese medicine preparation, which has the effects of promoting blood circulation and dispelling blood stasis, reducing swelling and relieving pain; it is used for the treatment of bruises, blood stasis, swelling and pain of muscles and bones, and can also be used as an adjuvant treatment for fractures. At present, there are more than a dozen domestic enterprises producing this product, and the manufacturers all adopt traditional standards to control product quality, and only conduct qualitative analysis, not quantitative analysis. Since the quality of Chinese patent medicines is closely related to the quality of Chinese herbal medicines, the curative effect depends on the content of the main act...
