Embodiment 1

[0022] Example 1, the snow chrysanthemum extract is obtained according to the following preparation method: in the first step, add hydrolytic enzyme to snow chrysanthemum according to the hydrolytic enzyme of 10U to 200U per gram of snow chrysanthemum, after adding the hydrolase, press snow chrysanthemum Chrysanthemum: the mass ratio of the extract is 1:8 to 1:60, and the enzymolysis extract with a pH of 3 to 7 is added to the snow chrysanthemum to form an extraction mixture, and then the extraction mixture is stirred, and the extraction mixture is heated at the same time to Carry out enzymatic extraction at 30°C to 60°C for 20min to 80min; the second step, after the enzymatic extraction is completed, filter the extraction mixture with a 300-mesh to 400-mesh filter bag to obtain the initial extract and residue respectively, and continue to extract the residue once with water to 2 times, the ratio of the mass of water added for each extraction to the mass of the enzymolysis ext...

Embodiment 2

[0023] Example 2, the snow chrysanthemum extract is obtained according to the following preparation method: the first step, adding 10U or 200U of hydrolase to the snow chrysanthemum according to the hydrolytic enzyme meter per gram of snow chrysanthemum, after adding the hydrolase, press the snow chrysanthemum Chrysanthemum: the mass ratio of the extract is 1:8 or 1:60, and the enzymolysis extract with a pH of 3 or 7 is added to the snow chrysanthemum to form an extraction mixture, then the extraction mixture is stirred, and the extraction mixture is heated to Carry out enzymatic extraction at 30°C or 60°C for 20min or 80min; in the second step, after the enzymatic extraction is completed, filter the extraction mixture with a 300-mesh or 400-mesh filter bag to obtain the initial extract and residue respectively, and continue to extract the residue once with water or 2 times, the ratio of the mass of water added for each extraction to the mass of the enzymolysis extract is 1:0...

Embodiment 3

[0024] Embodiment 3, as the preference of above-mentioned embodiment, hydrolase is more than one in cellulase and pectinase, when cellulase and pectinase are used in conjunction, the activity between cellulase and pectinase The ratio is 1:1 to 1:8. Adopt the method of this embodiment of the present invention, the extract yield rate of the extractum extract obtained after the primary extraction obtained after filtering after the first step is enzymatic hydrolysis and extraction is 82% or 86%, the effective The composition is 25% or 56% higher than the mass content of active ingredients in the snow chrysanthemum extract obtained according to the prior art.

Abstract

Relating to the technical field of Coreopsis tinctoria extraction, the invention provides a Coreopsis tinctoria extract and a preparation method thereof. The Coreopsis tinctoria extract is prepared by the method of: first step, enzymolysis extraction; second step, filtering; third step, microfiltration by a membrane with an aperture of 0.3micrometer-0.5micrometer; fourth step, ultrafiltration by a membrane with a molecular weight cut-off of 10000D-500000D; fifth step, ultrafiltration by a membrane with a molecular weight cut-off of 200D-1000D; and sixth step, drying, thus obtaining the Coreopsis tinctoria extract. With the method provided by the invention, the Coreopsis tinctoria extracted dry substance has high yield, and the cost and energy consumption can be effectively lowered, after microfiltration or ultrafiltration treatment by the membrane separation process, the amount of macromolecular substances is reduced, the filtrate does not generate flocculent precipitate in the storage process, the loss of effective ingredients is also reduced, the product quality is improved, and product quality safety is ensured.

Description

technical field [0001] The invention relates to the technical field of snow chrysanthemum extraction, and relates to a snow chrysanthemum extract and a preparation method thereof. Background technique [0002] Snow chrysanthemum has been drunk as tea for a long time in Xinjiang, especially Hotan. It is called "Gulqai" (Gulqai) in Uighur language, and it is the head of the annual herb C. tinctoria (C. inflorescence. It is currently the only rare alpine wild plant in Xinjiang that is as famous as snow lotus. It grows at the northern foot of Kunlun Mountain in Hotan, Xinjiang at an altitude of 3,000 meters. It has many important functions and has unique medicinal value and development and application prospects. People in Xinjiang call it: snow chrysanthemum, Kunlun snow chrysanthemum, Tianshan snow chrysanthemum, alpine snow chrysanthemum, two-color coreopsis, alpine fragrant chrysanthemum, etc. [0003] Snow chrysanthemum was first recorded in "Xinhua Compendium of Materia ...
