Abstract

The invention provides a method for measuring the content of Danshensu in shenshuaining capsules by utilizing an HPLC method, comprising the following steps: 1, weighing shenshuaining capsules into a measuring flask, crushing, adding methanol, performing ultrasound in water bath, placing in the ice-water bath, taking out, adding methanol, centrifuging, and taking the supernate as the test solution of the shenshuaining capsules; 2, weighing Danshensu sodium comparison products, placing in the measuring flask, performing ultrasound in water bath, taking out, placing in the ice-water bath, taking out, adding methanol to shake up for being served as the comparison products solution; 3, leading the chromatographic column to be Inertsil ODS-3 (4.6X 150mm 5mu m), the mobile phase to be methanol-water-glacial acetic acid, the volume ratio to be 19:80:1, the flow velocity to be 1.0ml/min, the detected wavelength to be 281nm, the sensitivity to be 0.01AUFS, the sample size to be 10 mu L, the column temperature to be 40 DEG C, and the theoretic plate number to be no less than 5000 calculated by chromatographic peak of the Danshensu; and 4, injecting Danshensu sodium comparison products solution and shenshuaining capsules test solution into liquid chromatograph, and measuring the chromatographic peak presented by shenshuaining capsules test solution with the same chromatographic retention as the Danshensu sodium comparison products solution. The invention provides a new comparison standard for accurately assessing the quality of shenshuaining capsules, thus strengthening controllability of product quality of shenshuaining capsules and being beneficial for comprehensive monitoring of product quality of shenshuaining capsules.

Description

technical field [0001] The invention relates to a method for determining the content of Chinese patent medicines by using an HPLC method, in particular to a method for measuring the content of danshensu in Shenshuaining capsules by using the HPLC method. Background technique [0002] Shenshuaining Capsule is a traditional Chinese medicine compound preparation composed of Danshen, Rhubarb, Pseudostellaria, Achyranthes bidentata, Coptis chinensis, Poria cocos, safflower, etc. Among them, Salvia miltiorrhiza is the monarch drug. Salvia miltiorrhiza is the dry root of the Lamiaceae sage plant. Modern pharmacological studies of traditional Chinese medicine have shown that salvia miltiorrhiza can effectively protect the damage to the renal tubular epithelium caused by in situ renal ischemia, and has a significant effect on the serum creatinine concentration after renal ischemia. , creatinine clearance rate and free water clearance rate can be effectively adjusted to a certain degr...
