Abstract

The invention provides a detection method of phenolic acid compounds in a compound radix salviae miltiorrhizae tablet, and the detection method comprises the following steps: preparing a standard solution, a reference solution and a to-be-tested product solution, passing through a high performance liquid chromatography for detection; then calculating a relative correction factor of the phenolic acid compounds relative to salvianic acid A sodium; and using a formula IV shown in the specification too obtain the phenolic acid compound content in the compound radix salviae miltiorrhizae tablet. According to the detection method, by detection of one compound (salvianic acid A sodium), simultaneous determination of multiple compounds (salvianic acid A, protocatechuic aldehyde, rosmarinic acid, lithospermic acid and salvianolic acid B) can be realized, and the detection method is simple, rapid, accurate, good in universality, labor, and material and financial resource saving, and can more fully reflect the quality of the compound radix salviae miltiorrhizae tablet.

Description

technical field [0001] The present invention relates to the field of detection of pharmaceutical compounds. It specifically relates to a detection method for medicines, in particular to a detection method for phenolic acid 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...
