Problems solved by technology

When the conventional process is made into injection or other liquid preparations, it will also degrade during storage, resulting in a decrease in content, and it is generally difficult to guarantee long-term medicinal requirements
There is no long-term stable scutellarin injection product on the market before the present invention

Abstract

A composite medicine in the form of solution for treating cardiovascular and cerebrovascular diseases features that it contains high-purity wild-scutelloside and pH regulator proportionally and the content of said high-purity wild-scutelloside can be stabilized for at least 18 months.

Description

technical field [0001] The invention relates to a high-purity scutellarin pharmaceutical composition and its medical application in the preparation of cardiovascular and cerebrovascular medicines. Background technique [0002] Scutellarin, also known as scutellarin, baicalein, scutellarin, scutellarin, and baicalin (from the Handbook of Active Ingredients in Plant Medicine: People's Medical Publishing House, March 1986, first edition, p946 ), the chemical name is 4′, 5, 6-trihydroxyflavone-7-O-glucuronide. Its structural formula is as follows: [0003] [0004] Scutellaria altissima L. leaves of labial plants, Scutellaria altissima L. leaves, stems and leaves of Scutellaria baicalensis Georgi, Erigeronbreviscapus (Vant.) Hand-Mazz and other plants of Compositae have a certain content of scutellarin . [0005] Erigeron breviscapus (Vant.) Hand-Mazz is a flavonoid active ingredient isolated from the whole herb of Erigeron breviscapus (Vant.) Hand-Mazz. It is a flavonoid ...
