Embodiment 1

[0035] Take drynaria drynaria 100kg, remove impurities, crush into coarse particles, add drinking water to extract twice according to the process of 8BV, 2h; 6BV, 1.5h, filter and combine the two medicinal liquids, and concentrate under reduced pressure to a relative density of 1.02g / ml (75°C), add chitosan oligosaccharide and activated carbon to the concentrated solution for adsorption, wherein, the amount of chitosan oligosaccharide added is 0.05% of the concentrated liquid mass, the amount of activated carbon added is 0.03% of the concentrated liquid mass, and the adsorption time is 60min , the adsorption temperature is 75°C; after the adsorbed sample solution is left to stand, it is filtered through a 400-mesh sieve to remove coarse carbon particles, and then filtered with a 0.1 μm microfiltration membrane, and the filtrate is concentrated and dried to obtain Drynaria rhizome extract.

[0036] After testing, the removal rate of arsenic was 73%, and the retention rate of na...

Embodiment 2

[0038] Take drynaria drynaria 100kg, remove impurities and crush into coarse particles, add drinking water to extract twice according to the process of 10BV, 2h; ml (75°C), add chitosan oligosaccharide and activated carbon to the concentrated solution for adsorption. Among them, the amount of chitosan oligosaccharide added is 0.03% of the concentrated liquid mass, the amount of activated carbon added is 0.03% of the concentrated liquid mass, and the adsorption time is 30min. The temperature of adsorption is 50°C; after the adsorbed sample solution is left to stand, the coarse carbon particles are filtered out with a 400-mesh filter, and then filtered with a 0.1 μm microfiltration membrane, and the filtrate is concentrated and dried to obtain Drynaria drynaria extract.

[0039] After testing, the removal rate of arsenic was 77%, and the retention rate of naringin was 82%.

Embodiment 3

[0041]Take drynaria drynaria 100kg, grind it into coarse particles after removing impurities, add drinking water to extract twice according to the process of 9BV, 1.5h; g / ml (75°C), add chitosan oligosaccharide and activated carbon to the concentrated solution for adsorption, wherein, the amount of chitosan oligosaccharide added is 0.03% of the concentrated liquid mass, the amount of activated carbon added is 0.05% of the concentrated liquid mass, and the adsorption time is 60min, the adsorption temperature was 65°C; after the adsorbed sample solution was left standing, the coarse carbon particles were filtered out with a 400-mesh filter, and then filtered with a 0.1μm microfiltration membrane, and the filtrate was concentrated and dried to obtain Drynaria drynaria extract.

[0042] After testing, the removal rate of arsenic is 80%, and the retention rate of naringin is 73%.

Abstract

The invention discloses a production method of a rhizoma drynariae extract. The production method comprises an extraction technology and a concentration technology, and further comprises a dearsenization technology, wherein the dearsenization technology comprises the steps of adding chitosan oligosaccharide and activated carbon to a concentrated solution obtained after concentration, and performing adsorption. According to the production method disclosed by the invention, the activated carbon and the chitosan oligosaccharide are used for adsorbing and removing heavy metal arsenic elements in the rhizoma drynariae extraction solutions, so that higher retention rate of naringin is guaranteed, and the removing rate of arsenic is greatly increased. Through verification with pilot scale production and amplification production, the method is efficient and low in cost, and is suitable for the trade of drugs and foods.

Description

technical field [0001] The invention relates to the technical field of plant extraction technology, in particular to a production method of drynaria drynaria extract. Background technique [0002] Rhizoma Rhizoma Drynariae is the dry rhizome of Quercus fern, a plant belonging to the family of Rhizoctoniaceae. "Chinese Pharmacopoeia" records that Rhizoma Rhizoma Rhizoma Rhizome has the effects of invigorating kidneys, strengthening bones, and relieving pain. It has been made into a variety of preparations for kidney deficiency, low back pain, tinnitus and deafness, loose teeth, tumbling, tendon fractures, external treatment of alopecia areata, vitiligo, etc.; at the same time, Rhizoma Drynaria can be used as a plant raw material for health food, It has a wide range of applications in health products. Oak fern is a fern plant, usually in places with sufficient water such as epiphytic rocks, tree trunks, ravines and canyons. It takes more than 5 years for oak fern to harvest f...
