Abstract

The invention discloses a medicine combination of snakegourd peel extract and allium macrostemon extract. The medicine combination is composed of 50-90 parts of snakegourd peel extract and 10-50 parts of allium macrostemon extract by weight; wherein, the total amino acid content in the snakegourd peel extract is not less than 50 percent, if calculated according to arginine, and the total saponin content in the allium macrostemon extract is not less than 50 percent, if calculated according to dioscin. The combination has stable quality, and high content of effective ingredients; the technique of the preparation method of the invention is stable, and has good reproduction quality. Proved by pharmacological tests, the combination has better protective effect on acute myocardial ischemia caused by rat hypophysin and canine myocardial ischemia due to coronary artery ligation. The medicine combination of the invention has promising application prospect in the respect of treating cardiovascular system diseases.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to a medicinal composition of Trichosanthes bark and Allium scallions extracts for treating diseases of the cardiovascular system and a preparation method thereof. Background technique [0002] Coronary heart disease belongs to the category of "chest obstruction" and "heart palpitation" in traditional Chinese medicine.
