Abstract

The invention relates to the technical field of medicines and in particular relates to application of a triterpenoid saponins compound. The invention provides application of the triterpenoid saponins compound with a structure formula I to preparation of a medicine for treating asthma. An experiment testifies that the triterpenoid saponins compound with the structure formula I has an obvious inhibition effect on a platelet activating factor receptor and can be used for alleviating tachypnea and accelerated frequency, caused by the asthma, and remarkably reducing the amount of Eos (Eosinophile granulocyte) in rat blood and reducing infiltration on trachea by the Eos; meanwhile, the secretion of GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor) in BALF (Bronchoalveolar Lavage Fluid) of guinea pigs can be inhibited and a PAF (Platelet-Activating Factor) level of blood serum of the guinea pigs is remarkably reduced, and the activation of inflammatory cells and the releasing of inflammatory transmitters are stopped, so that inflammation of the trachea is alleviated and smooth muscles of bronchus are relaxed; the high responsiveness of the trachea is reduced to treat the asthma, so that the triterpenoid saponins compound has the effect of treating the asthma and application value.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of triterpene saponin compounds. Background technique [0002] Bronchial asthma (abbreviation asthma) is a kind of common respiratory disease. Clinically, the main manifestations are recurrent wheezing, shortness of breath, chest tightness, coughing and other symptoms. A small number of patients may also experience chest pain. In severe cases, dyspnea and sudden death may occur. Asthma is one of the most common chronic diseases worldwide, and its prevalence has been increasing year by year in recent years. The pathogenesis of asthma is complicated, and there is no complete cure for it at present, and the effect of existing drugs is limited, so it is of great significance to develop new drugs for the treatment of asthma. [0003] In the past, asthma was considered to be an airway obstructive disease caused by smooth muscle spasm, but the current view is that ast...
