Abstract

The invention discloses an antioxidant activity detection method for a traditional Chinese medicine preparation for activating blood to resolve stasis, which includes steps of: 1) ultrasonically extracting the traditional Chinese medicine preparation with a methanol solution to obtain a sample solution; 2) dissolving 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH) in methanol to obtain a DPPH / methanol work solution; 3) mixing the sample solution, the DPPH / methanol work solution and methanol according to certain ratio to obtain a to-be-detected solution, a blank solution and a contrast solution,detecting the absorbancy of the solutions by means of a microplate reader, then calculating removal rate; 4) performing result correction with Vc being an internal standard substance, and expressing the antioxidant activity of the traditional Chinese medicine preparation by means of SR sample / SRVC. The invention also provides an application of the detection method for detecting the antioxidant activity of Xuefuzhuyu capsule.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine analysis, and in particular relates to a method for detecting antioxidant activity of a traditional Chinese medicine preparation for promoting blood circulation and removing blood stasis and its application. Background technique [0002] Blood stasis syndrome includes blood stagnation in veins and viscera due to poor blood supply, or stagnation of blood from menstruation in the body, or syndrome caused by dirty blood, which can be seen in coronary heart disease, cerebrovascular disease, pulmonary heart disease, liver cirrhosis, etc. disease. Patients with blood stasis syndrome usually have at least one of abnormal platelet and coagulation function, hemodynamic changes, peripheral circulation disorder, inflammatory response, and connective tissue disease. The use of blood-activating and stasis-removing drugs, especially traditional Chinese medicine preparations for promoting b...
