Embodiment 1

[0021] Take 1000g seabuckthorn, add 10 times the weight of seabuckthorn medicinal materials in water, soak for 0.5h, decoct for 1 hour, filter, add 8 times the weight of medicinal materials in water, decoct for 1 hour, filter out the medicinal liquid, combine and decoct twice Liquid, concentrated to a relative density of 1.05 at 60°C, adding ethanol to make the volume percentage of the alcohol content reach 75%, stirring, standing, and filtering, the relative density of the filtrate was 1.25 when the filtrate was concentrated to 65°C, and the ethanol was recovered to obtain a concentrated solution. Use macroporous resin for refining, collect the eluent, continue to concentrate, and dry the concentrated solution to obtain seabuckthorn flavonoid extract.

Abstract

The invention provides a seabuckthorn flavone extraction method. Sea-buckthorn is taken, water with the weight 10 times that of the sea-buckthorn medicinal material is added, soaking is performed for 0.5 hour, decocting is performed for 1 hour, and the decoction solution is filtered; water with the weight 8 times that of the medicinal material is added to the decoction dregs, decocting is performed for 1 hour, the steps of medicinal solution filtration and the like are performed, special concentration and drying equipment is adopted, and the prepared seabuckthorn flavone extract is high in content.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a method for extracting seabuckthorn flavonoids and an extract of seabuckthorn flavonoids. Background technique [0002] The plant seabuckthorn is a deciduous shrub belonging to the genus Hippophaeaceae. It is characterized by drought resistance, wind and sand resistance, and can survive on saline-alkali land, so it is widely used in water and soil conservation. Domestically distributed in North China, Northwest, Southwest and other places. Seabuckthorn is a medicinal and edible plant. The roots, stems, leaves, flowers, and fruits of seabuckthorn, especially the fruit of seabuckthorn, are rich in nutrients and biologically active substances, and can be widely used in many fields of the national economy such as food, medicine, light industry, aerospace, agriculture, animal husbandry and fishery. Seabuckthorn fruit used as medicine has the effects ...
