Embodiment 1
[0031] like figure 1 Shown, a kind of method for continuously extracting multiple active components from wolfberry residual fruit, is characterized in that: it comprises the steps:
[0032] (1) drying the defective fruit of Chinese wolfberry until the moisture content is below 11.82%, and pulverizing it with a pulverizer to obtain powder of the defective fruit of Chinese wolfberry;
[0033] (2) Add distilled water to the wolfberry residual fruit powder obtained in step (1) at a mass volume ratio of 1:20-30, heat to 75-85°C for extraction for 3 hours, and filter to obtain filtrate and filter residue;
[0034] (3) Concentrate the filtrate obtained in step (2) to 1 / 4 volume, add 3-5 times of ethanol, let it stand for 24 hours, filter to obtain filtrate and filter residue; wherein the filter residue is Lycium barbarum polysaccharide solution, and the filter solution is betaine solution;
[0035] (4) Dry the filter residue obtained in step (2), place it in ethanol at a mass volum...
Embodiment 2
[0038] On the basis of Example 1, the defective wolfberry fruit in the step (1) is a defective product produced during the preparation of wolfberry series products by a wolfberry production enterprise.
[0039]The Lycium barbarum polysaccharide solution in the step (3) uses glucose as a standard product, and adopts the phenol-sulfuric acid method to measure the content of Lycium barbarum polysaccharide in the Lycium barbarum polysaccharide solution.
[0040] The betaine solution in the step (3) uses betaine as a standard product, and adopts a spectrophotometric method to measure the content of betaine in the betaine solution.
[0041] The flavonoid solution in the described step (4) takes rutin as a standard product, adopts NaNO 2 -Al(NO 3 ) 3 Chromogenic method was used to determine the content of flavonoids in wolfberry solution.
[0042] The carotene solution in the step (5) uses β-carotene as a standard product, and adopts a colorimetric method to measure the carotene c...
Embodiment 3
[0046] A method for continuously extracting multiple active components from residual wolfberry fruit, comprising the steps of:
[0047] (1) drying the defective fruit of Chinese wolfberry until the moisture content is below 11.82%, and pulverizing it with a pulverizer to obtain powder of the defective fruit of Chinese wolfberry;
[0048] (2) Add distilled water to the wolfberry residual fruit powder obtained in step (1) at a mass volume ratio of 1:20 (g / mL), heat and extract at 75° C. for 3 hours, and filter to obtain filtrate and filter residue;
[0049] (3) Concentrate the filtrate obtained in step (2) to 1 / 4 volume, add 3 times of ethanol, let stand for 24h, filter to obtain filtrate and filter residue; the volume percentage concentration of ethanol is 100%.
[0050] (4) add distilled water to the filter residue in step (3), i.e. Lycium barbarum polysaccharide, and dissolve to obtain a Lycium barbarum polysaccharide solution; using glucose as a standard, adopt the phenol-su...
