Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.

[0021] 1. Preparation of Safflower Organic Solvent Extract

[0022] Safflower comes from Wuling Mountain in Hubei Province. The crushed dry safflower powder is soaked in ethanol with a volume percentage of 75%, the extract is obtained by cold soaking, the extract is evaporated to dryness under reduced pressure to obtain the extract, the extract is extracted with petroleum ether, and the extracted organic phase is evaporated to dryness under reduced pressure and concentrated into an extract, namely the safflower petroleum ether extract. The aqueous phase separated during the petroleum ether extraction is further added with ethyl acetate for extraction, and the extracted organic phase is evaporated to dryness unde...

Abstract

The invention discloses an application of a safflower organic solvent part extract in preparation of airway smooth muscle relaxation medicines. Research discovers that the safflower is capable of causing the relaxation of contractive airway smooth muscle, has a relaxation effect about three times higher than that of beta2 receptor stimulant isoprenaline clinically used at present, and can be applied to preventing and/or treating asthma. In addition, the detection on the cyclic tension of the isolated organ of an experimental rat also proves that the safflower organic solvent part extract has an effective airway smooth muscle relaxation effect and can be applied to relieving the airway obstruction; in short, a high-efficiency new medicinal source is provided for preventing and treating the asthma.

Description

technical field [0001] The invention relates to the application of safflower organic solvent part extract in preparing airway smooth muscle relaxing medicine. Background technique [0002] Bronchial asthma (hereinafter referred to as "asthma") is a common multiple chronic respiratory disease, and its pathogenesis is not yet fully understood. At present, there are at least 300 million people in the world, and there are nearly 30 million asthma patients in my country. Asthma has become the second leading cause of death and disability in the world after cancer. According to the latest survey released at the press conference of "my country's Asthma Disease Incidence, Treatment Progress and Asthma Management Ten-Year Progress News Bulletin", from 1990 to 2000, the incidence of asthma in mainland China increased from 0.91% to 1.97%. (more than doubled). The survey data of the three cities of Beijing, Chongqing, and Guangzhou in 2010 showed that the prevalence rates of childhood a...
