Salvianolic acid controlled porosity osmotic pump tablets and method of preparing the same

The invention discloses a salvianolic acid micropore osmotic pump controlled release tablet, comprising a tablet core and a coating; the tablet core is composed of salvianolic acid bulk drug, controlled release supplementary material, lubricant and moderate anhydrous ethanol; the weight ratio of the salvianolic acid bulk drug, the controlled release supplementary material and the lubricant is 50:150:1; the coating is composed of cellulose acetate, polyethylene glycol 400 solution and diethyl ester phthalate. In the invention, on the basis of controlling the content of 50-90% of salvianolic acid B, the content of 5-15% of tanshinol, protocatechualdehyde, salvianolic acid C, etc. in raw materials and by the optimal screening of penetrating agent, pore-forming agent, plasticizer and film thickness, an osmotic pump controlled release tablet which releases 85%-95% of a drug for 12 hours and conforms to the release characteristic of zero order kinetics is successfully prepared and used for preparing the drug for treating coronary heart disease and cerebral arteriosclerosis, which is good for the drug to form steady blood concentration in a body and lengthening the effective acting time of the drug, thus having good clinical compliance and treatment quality.

Chan tablet liquid chromatography-mass spectrometry determination method

The invention relates to a liquid chromatography-mass spectrometry determination method for a Holdan tablet. The method comprises the following steps: mixing psoralen glycoside, isopsoralen glycoside, hyperoside, quercetin 3-O-glucuronide, isoquercitrin, sennoside B, astragalus smicus glycoside, sennoside A, rosmarinic acid, alkannic acid, salvianolic acid B, nuciferine, salvianolic acid A, psoralen, isopsoralen, salvianolic acid C, rhein, neopsoralen isoflavone, psoralen and cryptotanshinone, and uniformly stirring to obtain a mixture; the method comprises the following steps of: preparing reference substance solutions A and B and a test sample solution by taking a sample as a reference substance and bakuchiol as a reference substance, injecting the reference substance solutions A and B and the test sample solution into a liquid chromatograph-mass spectrometer, obtaining mass spectrograms when A is in a positive ion mode and B is in a negative ion mode, and calculating the content of the effective components in the test sample according to the mass spectrograms under the chromatographic conditions that an Agilent C18 chromatographic column (4.6 mm * 250 mm, 5 [mu] m), the flow rate is 0.4 mL.min <-1 > and the sample injection volume is 2 [mu] L. The column temperature is 30 DEG C, and a 0.2% phosphoric acid aqueous solution (A)-acetonitrile (B) is used as a mobile phase for gradient elution.
