Embodiment 1

[0029] 150kg dried fruit of Sorbus adenocarpa, crushed to 10 meshes, added 3000kg of 0.2% acetic acid aqueous solution, extracted with a circulating ultrasonic extraction machine for 60min, ultrasonic power 6500W, extraction temperature 40°C; after the extraction was completed, centrifuged to remove slag to obtain argonia 2635kg of Sorbus arborica extract; the extract is adsorbed by pretreated DM21 macroporous resin, washed with water to remove impurities, and eluted with 70% ethanol to obtain 325kg of peach red pigment refined solution, concentrated under reduced pressure to obtain 37kg of concentrated solution, and freeze-dried to obtain black Aronia fruit extract 8.45kg (containing flavonoids 37%, proanthocyanidins 21%, anthocyanins 36%).

Embodiment 2

[0031] 500kg of fresh fruit of Sorbus adenocarpa, after beating, add 600kg of pure aqueous solution, extract with a circular ultrasonic extractor for 30min, with ultrasonic power of 1500W, and extraction temperature of 50°C; add 400kg of pure water to the dregs and extract once again; combine the two extracts, Centrifugal filtration to remove slag to obtain 1375 kg of Sorbus nigra extract; the extract was absorbed by pretreated AB-8 macroporous resin, washed with water to remove impurities, and eluted with 60% methanol solution to obtain 178 kg of eluate, concentrated under reduced pressure to obtain concentrated Liquid 31kg, spray-dried to obtain 3.27kg (containing flavonoids 35%, proanthocyanidins 23%, anthocyanins 37%) of Aronia nigricarpa extract.

Embodiment 3

[0033] 10kg dried fruit of Sorbus adenocarpus, crushed to 20 mesh, add 120L of 10% ethanol solution, extract for 45min with a circular ultrasonic extractor, ultrasonic power 1500W, extraction temperature 30°C; add 100L of 10% ethanol solution to the dregs and extract once more Merge the 2 extracts, centrifuge and filter to remove slag to obtain 195L of Sorbus black fruit extract; the extract is absorbed by pretreated D101 macroporous resin, washed with water to remove impurities and eluted with 50% acetone solution to obtain 28L of eluate, Concentrate under reduced pressure to obtain 2.7 kg of concentrated solution, and vacuum-dry to obtain 485 g of Aronia nigra extract (containing 39% flavonoids, 21% proanthocyanidins, and 28% anthocyanins).

Abstract

The invention discloses a production method of aronia melanocarpa extract. The method particularly comprises the steps that aronia melanocarpa fruits are broken, 6-20 times of extraction solvent is added, then circulating ultraphonic (wave) extraction, centrifugal filtration, macroporous resin adsorption, elution and concentration drying are sequentially performed, and the aronia melanocarpa extract is obtained. The production method of the aronia melanocarpa extract utilizes a circulating ultraphonic extraction-resin adsorption purification coupling technology and has the advantages of being simple in technology, high in extraction efficiency, production efficiency and product quality, capable of saving energy and achieving industrialized production and the like.

Description

technical field [0001] The invention relates to a technology for extracting and purifying plant active components, in particular to a production method for Aronia nigra extract. Background technique [0002] Aornia mealnocarpa Elliot, scientific name is Aornia mealnocarpa Elliot, is a perennial deciduous shrub belonging to Rosaceae, and its fruit is purple-black berry. Sorbus nigra is native to the Americas and is an afforestation species introduced in my country in arid areas. It is currently widely cultivated in Northeast China, with a planting area of ​​more than 1,000 hectares. [0003] Aronia adenocarpus combines edible, medicinal, garden and ecological values. The fruit is rich in flavonoids, anthocyanins, proanthocyanidins and other polyphenol active substances, which have anti-oxidation, anti-inflammatory, anti-cancer, hypoglycemic and other biological properties. It has special effects on the treatment of cardiovascular and cerebrovascular diseases such as heart di...
