preparation example Construction

[0035] The preparation method of Ophiopogon japonicus fibrous root extract provided by the invention comprises the following steps:

[0036] A, get the fibrous root of Ophiopogon japonicus, wash, dry, pulverize into fine powder, add the ethanol or water of 60%~80% mass concentration of 6 to 8 times the weight of the Radix Radix Radix et Rhizoma, and stir for 10 to 30 minutes, filter through a 60-mesh sieve to obtain Ophiopogon japonicus fibrous root slurry;

[0037] Among them, in order to increase the contact area between the fibrous root of Ophiopogon japonicus and the extraction solvent, the fibrous root of Ophiopogon japonicus was pulverized into a fine powder according to the 2015 edition of the Chinese Pharmacopoeia. In the steps of the present invention, ethanol or water is used as the extraction solvent, no harmful organic solvent is involved, the production process is pollution-free, the cost is low, and it is suitable for preparing functional food. The preferred mas...

Embodiment 1

[0049] A, get Ophiopogon japonicus fibrous root 100kg, clean, dry, pulverize to be fine powder, add the ethanol of 600kg 60% mass concentration and stir 20 minutes, obtain Ophiopogon japonicus fibrous root slurry by 60 mesh sieve filtration.

[0050] b. Add 600kg of 60% ethanol in the extraction tank, start the plunger pump, and control the pressure at 1.8-2.0Mpa, so that the Ophiopogon japonicus fibrous root slurry is dispersed into a mist through the nozzle and sprayed into the extraction tank under the pressure of the plunger pump. Inside, after 2 hours of extraction, an extract is obtained, and the extract is first filtered through a liquid filter press with a 200-mesh coarse filter, and then passed through a connecting pipeline and then passed through a 800-mesh fine filtration to obtain a filtrate 1 and a filter residue 1.

[0051] c. Add 600kg of water to filter residue 1, and operate according to steps a and b to obtain filtrate 2 and filter residue 2; filter residue 2 ...

Abstract

The invention belongs to the field of functional food, and particularly relates to a radix ophiopogon root extract and a preparation method and application thereof. The content of polysaccharide in the extract is 20-30%, the content of total flavone is 1.0-1.3%, and the content of total saponin is 1.2-1.4%. The technical problem that the yield of a prior method for extracting the radix ophiopogonroot is low is solved. The invention discloses the preparation method of the extract, which comprises the following steps of: a, crushing radix ophiopogon root, adding a solvent, stirring, and filtering to obtain radix ophiopogon root slurry; b, taking ethanol or water as an extraction solvent, carrying out spray extraction on the radix ophiopogon root slurry to obtain an extract solution, and carrying out solid-liquid separation to obtain filtrate 1 and filtrate residue 1; c, using the filter residue 1 as a raw material to obtain filtrate 2 and filter residue 2 according to the operations ofthe steps a and b; washing filter residue 2 with water, and separating to obtain filtrate 3 and filter residue 3; d, mixing the filtrates, concentrating and drying to obtain the radix ophiopogon rootextract. The method has the advantages of high yield, short extraction time and cost saving.

Description

technical field [0001] The invention belongs to the field of functional foods, and particularly relates to an extract of the fibrous root of Ophiopogon japonicus and a preparation method and application thereof. Background technique [0002] Ophiopogon japonicus is the dry root tuber of Ophiopogon japonicus (Thunb.) Ker-Gawl. of the Liliaceae plant. Its taste is sweet and bitter, and its nature is slightly cold. Traditionally, Ophiopogon japonicus has always been used as medicine in medicine and health food, and a large number of fibrous roots associated with the tuber are often discarded during the harvesting and processing process. However, according to our research, the chemical components contained in the fibrous root of Ophiopogon japonicus, such as saponins, polysaccharides, and total flavonoids, are consistent with the types of active ingredients contained in the tuberous root of Ophiopogon japonicus. As far as industrial production is concerned, the fibrous root of ...
