Embodiment 1

[0021] Weigh 2g of seabuckthorn fruit, wash, drain and grind into powder, add 10ml of 40% ethanol solution and 2.5ml of vegetable oil, ultrasonically extract for 40min, and obtain the extract after filtering. Separate the liquid, evaporate the water-alcohol phase to dryness, and obtain a brown powdery solid, which is the purified total flavonoids of seabuckthorn.

Embodiment 2

[0023] Weigh 2g of seabuckthorn fruit, wash, drain and grind into powder, add 10ml of 60% ethanol solution and 2.5ml of vegetable oil, ultrasonically extract for 40min, and obtain the extract after filtering. Separate the liquid, evaporate the water-alcohol phase to dryness, and obtain a brown powdery solid, which is the purified total flavonoids of seabuckthorn.

Embodiment 3

[0025] Weigh 2g of seabuckthorn fruit, wash, drain and grind into powder, add 10ml of 70% ethanol solution and 2.5ml of vegetable oil, ultrasonically extract for 40min, and obtain the extract after filtering. Separate the liquid, evaporate the water-alcohol phase to dryness, and obtain a brown powdery solid, which is the purified total flavonoids of seabuckthorn.

Abstract

The invention discloses a technology for purifying total flavones of hippophae. The technology for purifying the total flavones of hippophae comprises the following steps: cleaning hippophae rhamnoides, draining and grinding the drained hippophae rhamnoides into powder; adding ethanol solution and vegetable oil, carrying out ultrasonic extraction for a period of time, and filtering to obtain extracting solution; carrying out liquid separation on the extracting solution, thus obtaining a water-alcohol phase; and drying the water-alcohol phase into powder, so that the purified total flavones of hippophae are obtained. The technology for purifying the total flavones of hippophae has the advantages that purity of the obtained total flavones of hippophae is high, operation is simple, cost is low and large scale production can be realized.

Description

technical field [0001] The invention belongs to the field of food and drug processing, and relates to a purification process of total flavonoids of seabuckthorn. Background technique [0002] Sea buckthorn flavonoids contain active ingredients such as quercetin, isorhamnetin and kaempferol. It has the functions of lowering blood pressure, lowering blood fat, reducing blood viscosity, enhancing blood vessel elasticity, and anti-atherosclerosis. It is the "nemesis" of cardiovascular and cerebrovascular diseases. It is the health care product of choice for middle-aged and elderly people to prevent and treat cardiovascular and cerebrovascular diseases, and the current market demand is huge. The current mainstream extraction process is supercritical CO2 extraction, which has high cost and low purity. However, the traditional purification process adopted by domestic pharmaceutical factories is generally decoction, and the purity of the resulting product is generally lower than 1...
