[0037] Embodiment 1 Shuxuening liposome injection

[0038] prescription

[0039]

[0040] Preparation Process:

[0041] (1) Weigh 7g of Ginkgo biloba extract, 50g of dioleoylphosphatidylcholine, 30g of octadecylamine, 20g of polyoxyethylene alkylamine and 1g of sodium metabisulfite in a pear-shaped bottle, add 1500ml volume A mixed solution of ethanol and acetone with a ratio of 1:1 was heated and stirred at 50°C to dissolve it, and then the organic solvent was removed under reduced pressure on a rotary evaporator to form a uniform transparent phospholipid film on the bottle wall;

[0042] (2) Under the protection of nitrogen, add 1500ml citrate buffer solution with pH 6.2 to the bottle, shake gently to elute the phospholipid film and disperse it in the medium to swell and hydrate, then do gradient homogenization at 100bar to 600bar for 4~ 6 times, 0.22 μm microporous membrane filtration, made Shuxuening liposome;

Abstract

The invention discloses a Shuxuening lipidosome injection. The Shuxuening lipidosome injection is mainly prepared by using a ginkgo biloba extract, dioleoylphosphocholine, octadecylamine, polyoxyethylene alkylamine, sodium metabisulfite and sodium chloride. Compared with the prior art, the Shuxuening lipidosome injection disclosed by the invention is suitable for large-scale industrial production and has the advantages that the stability and bioavailability of a preparation are greatly improved, product quality is improved and toxic and side effects are reduced.

Description

technical field [0001] The invention relates to a novel injection preparation of ginkgo leaf extract, in particular to a liposome injection of ginkgo leaf extract and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] The composition of Shuxuening injection is Ginkgo biloba extract, and its active ingredients are mainly flavonoid glycosides and terpenoid lactone active substances, including: quercetin, camellin, ginkgo triglycerides, ginkgolides, picrolactone, etc. . Ginkgo is one of the oldest plants on earth. It is a plant of the Ginkgo family Ginkgo family. This tree species has strong vitality. It is not uncommon for a tree to be thousands of years old. It can be called the "old birthday star" in the plant world. It is recorded in "Compendium of Materia Medica" that Ginkgo biloba can invigorate the heart and nourish Qi, nourish the kidney and moisten the lungs, strengthen the brain and refresh the mind, and prolong ...
