Embodiment 1

[0028] The method for extracting flavonoids and ellagic acid from pomegranate flower, it comprises the following process steps in sequence:

[0029] (1) Pretreatment: Take 10 liters of edible ethanol with an alcohol content of 15% (v / v) and a temperature of 25°C, put it in a 20-liter stainless steel container, and soak 1000 grams of pomegranate flowers in edible ethanol at a constant temperature for 8 minutes After removing the dust, mold and other microorganisms adhering to the surface of the pomegranate flowers, take out the pomegranate flowers and place them on a 40-mesh sieve and rinse them with deionized water at a temperature of 25°C for 4 minutes, and then use a tunnel-type oven with a temperature of 85°C in the box. Oven dries the pomegranate flower, makes the moisture content of pomegranate flower 4%, weighs 965 grams;

[0030] (2) Extraction:

[0031] (1) Get 14475 grams of deionized water, place it in a 30-liter stainless steel container, put 965 grams of pomegrana...

Abstract

The invention discloses a method for extracting flavonoid substance and ellagic acid from pomegranate flower, which comprises the following procedures: dip the pomegranate flower in edible ethanol fora while, then take it out and place it on a screen, wash it with deionized water, then dry the pomegranate flower; mix and heat the pomegranate flower and the deionized water according to certain proportion, stir them under constant temperature, stop the heating and place the mixture till stillness, filter the mixture with the screen to get preliminary extraction fluid; filter the residue and repeat the previous procedure to get secondary extraction fluid; mix the preliminary extraction fluid and the second extraction fluid to get mixed extraction fluid; conduct ultrafiltration for the mixedextraction fluid to realize anti-penetration concentration of the acquired filtrate; spray and dry the filtrate to get brownish powder with flavonoid content of 5 to 8 per cent and ellagic acid content of 1 to 1.5 per cent. Therefore, the method, which converts the waste into useful material and greatly enhances the added value and comprehensive utilization rate of agricultural products, has no residual organic solvent, brings no harm and toxic content and complies with the quality and safety authentication requirements for drug and health-improving product.

Description

technical field [0001] The invention relates to a method for extracting flavonoids and ellagic acid, more specifically, the invention relates to a method for extracting flavonoids and ellagic acid from pomegranate flowers. technical background [0002] Pomegranate flower is the most nutrient-rich part of pomegranate, especially rich in flavonoids and ellagic acid. [0003] Both flavonoids and ellagic acid are strong antioxidants. According to foreign media reports: "ellagic acid is the most effective antioxidant found so far." [0004] In terms of human health care, flavonoids and ellagic acid have the effect of strengthening arteries, veins and capillaries, effectively remove various free radicals in the body and protect LDL from oxidation (can effectively inhibit the formation of atherosclerotic plaque in blood vessels ), achieve the effect of preventing and treating cardiovascular and cerebrovascular diseases, and have a certain effect on preventing and improving eye dis...
