Abstract

The invention discloses a medicine by using common aspidistra extract as an active ingredient. The method comprises the following steps: soaking common aspidistra powder in an alcohol solution, heating and refluxing; evaporating filtrate to be dry; completely dissolving alcohol extract of common aspidistra with water, and extracting with petroleum ether; extracting with chloroform, and evaporating the petroleum ether to be dry to obtain an extract which is the common aspidistra extract. The common aspidistra extract can be used for relaxing preshrunk mouse tracheal smooth muscles induced by potassium chloride or acetyl choline, and the relaxation can be 97.51 percent. Therefore, the common aspidistra extract or a medicine using the common aspidistra extract as an active ingredient can be used for treating, preventing, relieving or improving diseases which can be treated, prevented, relieved or improved by relaxing smooth muscles, or reducing the risk of diseases which can be treated, prevented, relieved or improved by relaxing smooth muscles, for instance, treating, preventing, relieving or improving asthma or reducing the risk of body suffering asthma.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to the relaxation and pre-contraction of the tracheal smooth muscle with the extract of the leaves of Ruo, in particular to the treatment, prevention, relief or improvement with the extract of the leaves of the leaves as the active ingredient, which can be treated, prevented, relieved or improved by relaxing the smooth muscles disease. Background technique [0002] At present, with the deteriorating air quality, respiratory system diseases have gradually attracted people's attention.
