Problems solved by technology

The content determination of tanshinone compounds in Compound Danshen Tablets in the 2010 edition of "Pharmacopoeia of the People's Republic of China" only controlled tanshinone II A For one ingredient, there are few monitoring indicators, which are not enough to fully reflect the quality of Compound Danshen Tablets
At present, there are many literature reports on the multi-index content determination method of tanshinone compounds in Compound Danshen Tablets, but there are deficiencies such as unreasonable selection of detection indicators, rare reference substances, and poor universality of the established method.

Embodiment 1

[0097] According to the specification requirements of Compound Danshen Tablets in the 2010 edition of the Pharmacopoeia of the People's Republic of China, 20 batches of samples of Compound Danshen Tablets were taken for determination.

[0098] Determine according to high performance liquid chromatography (Appendix VI D of "Pharmacopoeia of the People's Republic of China" 2010 edition).

[0099] Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel is used as filler; methanol-water (73:27) is used as mobile phase; detection wavelength is 248nm. The number of theoretical plates according to Tanshinone II A The calculation should be no less than 2000.

[0100] Preparation of standard solution: take tanshinone compound reference substance, add methanol to dissolve it; in μg / mL, the mass volume ratio of dihydrotanshinone I reference substance to methanol is 10:1; cryptotanshinone reference substance, tanshinone I reference substance or Tanshino...

Abstract

The invention relates to the field of drug compound detection, in particular to a method for detecting tanshinone compounds in compound salvia tablets. A plurality of components of the same type including dihydrotanshinone I, cryptotanshinone, tanshinone I and tanshinone IIA can be simultaneously detected by detecting the index component of the tanshinone IIA. The method is simple and convenient, is fine in universality and can be used for more completely reflecting the quality of the compound salvia tablets.

Description

technical field [0001] The invention relates to the field of detection of pharmaceutical compounds, in particular to a method for determining tanshinone compounds in compound danshen tablets. Background technique [0002] Compound Danshen Tablets is a commonly used cardiovascular and cerebrovascular drug in clinical practice. It is a traditional Chinese medicine preparation made of Danshen, Panax notoginseng and borneol as raw materials and auxiliary materials. It can promote blood circulation, remove blood stasis, regulate qi and relieve pain. Compound Danshen Tablets are recorded in the 2010 edition of the "Pharmacopoeia of the People's Republic of China" and are divided into three specifications. The first specification is film-coated small tablets, each weighing 0.32g, which is equivalent to 0.6g decoction pieces; the second specification is film-coated large tablets. Each piece weighs 0.8g, which is equivalent to 1.8g of decoction pieces; the third specification is suga...
