A kind of steam explosion pretreatment method of Ginkgo biloba

Abstract

In order to eliminate the influence of compact structures of cell walls of ginkgo leaves on the dissolution of active ingredients and improve the dissolution efficiency of ginkgo leaf extract, the invention provides a steam explosion pretreatment method for the ginkgo leaves. The method comprises the following steps of: adding absolute dry ginkgo leaves into solution in a mass ratio of 1:0-1:4, and soaking at normal temperature for 5 to 180 minutes; putting the soaked materials into a steam explosion tank, introducing a steam explosion medium, raising the temperature in the tank to 30 to 250 DEG C, keeping the temperature for 1 to 30 minutes, and performing steam explosion; and releasing pressure quickly, and releasing the treated materials in the steam explosion tank to a constant-pressure container to obtain the materials which is subjected to steam explosion pretreatment. By the steam explosion pretreatment, structures of the ginkgo leaves are loosened to form obvious porous structures, and the dissolution efficiency of active ingredients is improved, but the active ingredients in the raw materials are not damaged; and the active ingredients of the ginkgo leaves which are subjected to the steam explosion can be extracted or crushed or subjected to superfine crushing directly to prepare various ginkgo products.

Description

technical field [0001] The invention belongs to the field of processing and application of traditional Chinese medicinal materials, in particular to a method for enhancing the dissolution of ginkgo active ingredients by steam explosion. Background technique [0002] Ginkgo biloba (Gingko biloba L) is a plant of the genus Ginkgoaceae (Ginkgoaceae), also known as ginkgo tree and Gongsun tree. It is a relict plant of the Permian in the Paleozoic Era. It is called the "living fossil" of gymnosperms and is widely distributed in my country. Since the 1960s, domestic and foreign scholars have done a lot of research on its chemical composition, pharmacological effects and clinical application. Pharmacological studies have shown that Ginkgo biloba extract can expand coronary blood vessels, increase cerebral blood flow, improve brain nutrition, and has obvious anti-platelet activating factor and antibacterial effects, especially the unique effect of Ginkgo biloba extract on the nervou...

AI Technical Summary

Problems solved by technology

Therefore, no matter what extraction method is used, the degree of damage to plant cells will directly affect the extraction efficiency and subsequent processing.

[0004] Traditional methods generally use mechanical pulverization to crush materials, but because plant cells have great resistance to external forces, the degree of damage to plant cells by mechanical treatment is limited

However, if the plant-based traditional Chinese medicine is to be crushed to the micron level, the energy consumption will increase and the cost will increase.
