Embodiment 1

[0012] Example 1 Chrysanthemum total flavonoids against aconitine-induced arrhythmia in rats

[0013] SD rats, half male and half female, weighing 240g-280g, were randomly divided into four groups and anesthetized by intraperitoneal injection (ip) of 1.2g / kg urethane. The supine position was fixed, the femoral vein was exposed, and the retained needle was placed. Adopt standard limb leads, connect to PcLab machine, record electrocardiogram, respectively ip total flavonoids of chrysanthemum, solvent 1.4ml / kg, salvia miltiorrhiza injection 6.0g / kg. After 20 minutes, 30 μg / kg of aconitine was injected. Observation indicators: premature ventricular contraction (VE), ventricular tachycardia (VT), ventricular fibrillation (VF) appearance time, duration (number of occurrences) and end time, and arrhythmia score (Score). See Table 1 and Table 2 for the results.

[0023] Example 2 Chrysanthemum total flavonoids against chloroform-induced arrhythmia in mice

[0024] NIH mice, half male and half female, body weight 20g-25g, were randomly divided into three groups, respectively intraperitoneally injected (ip) 120mg / kg chrysanthemum total flavonoids, 30mg / kg quinidine, 4.2ml / kg solvent, after 10min, each Rats were put into 500ml glass covers respectively, and cotton balls soaked with 2ml chloroform were placed in advance in the covers. When the mice stopped breathing for 5 seconds, they were taken out and connected to lead electrocardiograms to observe the incidence rate of ventricular fibrillation (VF) and rhythm of the mice.

Abstract

The present invention provides an application of chrysanthemum total flavone in preparation of medicine for cuing arrhythmia. The chrysanthemum total flavone provided by said invention is effective component of chrysanthemum flower, the total flavone content is geater than 50%, and the dosage form prepared by using chrysanthemum flavone and medicinal exipient can be liquid preparation and solid preparation. Its therapeutic effect is obvious and reliable.

Description

technical field [0001] The invention belongs to the use of traditional Chinese medicine, and relates to the application of total flavonoids of chrysanthemum in the preparation of medicines for treating cardiovascular diseases, in particular to the application of total flavonoids of chrysanthemums in the preparation of medicines for treating arrhythmia. Background technique [0002] Cardiac arrhythmia is a common disease. Various types of heart disease, high blood pressure, senile emphysema, etc. can induce arrhythmia, and malignant arrhythmia can be life-threatening in an instant. Therefore, the prevention and treatment of arrhythmia is of great significance. However, clinical studies have shown that various types of antiarrhythmic chemicals are proarrhythmic [1，2] , so antiarrhythmic Chinese medicine will be more and more favored by doctors and patients. However, there are not many varieties of antiarrhythmic Chinese patent medicines. Chrysanthemum is a common medicinal ...
