Problems solved by technology

[0004] The problems existing in the prior art are: 1. raw material processing is cumbersome, and the next process needs to be deseed, so it is not suitable for large-scale industrial production; 2. the extraction method is rough, and the product after extraction is a crude product without separation and purification. Low, low target component content, 85% in terms of anthocyanin recovery, but wherein the anthocyanin content is only 4 to 5%; ③ product color is poor (brown), unfavorable for product application

Embodiment 1

[0039] After cleaning 500 grams of raw materials, they were crushed at low temperature, and the crushed raw materials were added to 3 times the weight / volume of ethanol aqueous solution with a pH value of 6 and a mass percent of 10%, countercurrently extracted at 50°C for 6 hours, collected the extract, and decompressed Concentrate to obtain 19.16 grams of elderberry fruit anthocyanin extract.

Embodiment 2

[0041] After cleaning 500 grams of raw materials, crush them at low temperature, add 4.5 times the weight / volume of the crushed raw materials to ethanol with a pH value of 4, and a mass percentage of 20%, conduct countercurrent extraction at 40°C for 4 hours, collect the extract, and concentrate under reduced pressure , to obtain 19.51 grams of elderberry fruit anthocyanin extract.

Embodiment 3

[0043] After washing 500 grams of raw materials, grind them at low temperature, add 6 weight / volume times of the raw materials, pH value of 3, and 30% ethanol by weight, and conduct countercurrent extraction at 25°C for 3 hours, collect the extract, and concentrate under reduced pressure , to obtain 19.03 grams of elderberry fruit anthocyanin extract.

Abstract

The invention discloses a method for extracting anthocyanin from elderberry fruits. The method comprises the following steps: (1) crushing material at low temperature after cleaning; (2) adding the crushed material into 3-6 weight / mass times of ethanol water, of which the pH value is 3-6 and the mass percent is 10-30%, carrying out countercurrent extraction for 3-6 hours at 25-50 DEG C, and (3) collecting extracting solution, and concentrating under reduced pressure to obtain the anthocyanin extract of the elderberry fruit. By adopting the countercurrent extraction method, the anthocyanin ingredient can be extracted more fully, and compared with the method in the prior art, the method has the characteristics that the material treatment is easier; the solvent is saved; the extraction efficiency is high and the cost is low, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of extracting effective parts of plants, in particular to a method for extracting anthocyanins from elderberry fruit. Background technique [0002] Elderberry genus Sambucus L. is a plant of Caprofoliaceae Caprifoliaceae. There are about 20 species in the world, distributed in temperate and subtropical regions. There are about 5 species of Elderberry genus in my country, namely S.adnata Wall.ex DC., Elderberry S.chinensis Lindl., Elderberry S.williamsiiHance, Siberian Elderberry S.sibirica Nakai, Western Elderberry S.nigraLinn. are distributed in all provinces and regions in the north and south. This genus of plants has the effects of expelling wind and dampness, relaxing tendons and activating blood circulation. It is widely used in Chinese folks to treat rheumatic arthralgia, bruises, fractures, jaundice, urticaria and edema. [0003] Now the extraction method of natural compounds such as anthocyanins in t...
