Embodiment 1

[0012] Example 1, a method for extracting seabuckthorn flavonoids from seabuckthorn fruit, adding pure water to the seabuckthorn fruit and soaking for 3 hours, then boiling at 50°C for 4 hours, crushing and filtering through a 120-mesh sieve to obtain the first extract , then boil the filter residue with water at 60°C for 3 hours, crush and centrifuge to obtain the second extract, mix the first extract and the second extract, heat and concentrate to obtain a concentrate, add ethanol solution to the concentrate for extraction to obtain the extract liquid, the extraction temperature is 40°C, the extraction time is 1.5 hours, the weight ratio of the concentrated solution to the ethanol solution is 1:3, and the concentration of the ethanol solution is 60%. The extract is boiled to remove ethanol, concentrated and dried to obtain seabuckthorn flavonoids.

Embodiment 2

[0013] Example 2, a method for extracting seabuckthorn flavonoids from seabuckthorn fruit, adding pure water to the seabuckthorn fruit to soak for 4 hours, then boiling at 55°C for 4.5 hours, crushing and filtering through a 120-mesh sieve to obtain the first extract , then boil the filter residue with water at 70°C for 3 hours, pulverize and centrifuge to obtain the second extract, mix the first extract and the second extract, heat and concentrate to obtain a concentrate, add ethanol solution to the concentrate for extraction to obtain the extract liquid, the extraction temperature is 45°C, the extraction time is 2 hours, the weight ratio of the concentrated solution to the ethanol solution is 1:4, and the concentration of the ethanol solution is 70%. The extract is boiled to remove ethanol, concentrated and dried to obtain seabuckthorn flavonoids.

Embodiment 3

[0014] Example 3, a method for extracting seabuckthorn flavonoids from seabuckthorn fruit, adding pure water to the seabuckthorn fruit and soaking for 6 hours, then boiling at 60°C for 5 hours, crushing and filtering through a 120-mesh sieve to obtain the first extract , then boil the filter residue with water at 80°C for 3 hours, pulverize and centrifuge and filter to obtain the second extract, mix the first extract and the second extract, heat and concentrate to obtain a concentrate, add ethanol solution to the concentrate for extraction to obtain the extract liquid, the extraction temperature is 50°C, the time is 2.5 hours, the weight ratio of the concentrated solution to the ethanol solution is 1:5, and the concentration of the ethanol solution is 80%. The extract is boiled to remove ethanol, concentrated and dried to obtain seabuckthorn flavonoids.

Abstract

The invention relates to a method for extracting seabuckthorn flavone from seabuckthorn fruits. The method comprises the steps: adding pure water to the seabuckthorn fruits, soaking for 3-6 hours, then cooking for 4-5 hours at the temperature of 50-60 DEG C, and crushing and filtering, to obtain a first extract liquid; then adding water to the filter residue, cooking for 3 hours at the temperatureof 60-80 DEG C, crushing, centrifuging and filtering to obtain a second extract liquid; mixing the first extract liquid and the second extract liquid, and heating and concentrating to obtain a concentrated solution; adding an ethanol solution to the concentrated solution, and extracting to obtain an extract liquid; and steam-cooking the extract liquid to remove ethanol, and then concentrating anddrying to obtain the seabuckthorn flavone product. The seabuckthorn fruits have high extraction rate, the yield can reach 98%, the preparation is convenient, large-scale factorization production canbe performed, seabuckthorn fruit paste waste residues are reused, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for extracting effective components of plants, in particular to a method for extracting seabuckthorn flavonoids from seabuckthorn fruits. 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 precious medicinal and edible plant resource, which is widely used in health care products and pharmaceutical raw materials. Seabuckthorn fruit used as medicine has the effects of relieving cough and reducing phlegm, invigorating stomach and eliminating food, promoting blood circulation and dispelling blood stasis. According to modern medical research, seabuckthorn can lower cholesterol, relieve angina pectoris, and ...
