Problems solved by technology

Although there have been many reports on the research on ginkgolides and their preparations in the prior art, the research on ginkgolides has not stopped, especially for the separation of ginkgolide monomers and research on derivatives thereof. There are literature reports
At present, the research on the effective monomers of ginkgolides has reported the structures of ginkgolides A, B, and C, and preparing ginkgolides into injections. A very important technical problem is the control of product quality. Up to now So far, no method has been found that can accurately control the content of active ingredients in ginkgolide injection products. Moreover, in the preparation process of ginkgolide injections, the selection of co-solvents is also very important, which directly affects the stability of the product and clinical efficacy. curative effect

Abstract

The invention discloses a ginkgolide injection. The injection contains ginkgolide and meglumine. The ginkgolides include ginkgolides A, B, and K. The ginkgolide injection product meets the requirements of fingerprints, and the product quality is It is controllable and stable, and when meglumine is added, it has a good solubilizing effect on ginkgolide. The invention also discloses a pharmaceutical composition containing ginkgolides A, B and K.

Description

technical field [0001] The invention relates to preparations of ginkgolides, in particular to injections containing ginkgolides. The injections are prepared from ginkgolides, which are extracts of ginkgo leaves from traditional Chinese medicines, and belong to the field of medicines. Background technique [0002] Ginkgolide is an effective substance extracted from the leaves of the Chinese herbal medicine Ginkgo biloba, which can be further subdivided into Ginkgolide A, B, C, and K structurally (Ginkgolide K is a Ginkgolide newly discovered by the inventor. ester monomer, another case application), etc., have had detailed bibliographical reports for the extraction method of ginkgolide, for example, people such as Li Xingang have introduced the laboratory extraction method of ginkgolide (referring to Li Xingang etc., ginkgolide in ginkgo leaf Laboratory extraction method research, China Pharmaceutical Industry Journal, 1998 No. 1), Chinese patent document CN1195665A has intro...
