Embodiment 1

[0024] The preparation of embodiment 1 fig polysaccharide of the present invention

[0025] Fig polysaccharide of the present invention can adopt the method for bibliography to extract Fig polysaccharide, also can adopt following method to prepare:

[0026] Take 100 g of figs, add water, and extract 2 times for a total of 6 hours at a temperature of 80 °C with a material-to-liquid ratio of 1:18; the optimal process for the separation of fig polysaccharides by ethanol precipitation is obtained by adding ethanol when the concentration ratio is 1:1. The final concentration of 60% precipitation for 18h is the best extraction and separation process. After the precipitate was obtained, it was freeze-dried and stored in a refrigerator at 4°C. Dissolve 5 mg of the dried precipitate in 50 mL of distilled water, and the anthrone sulfate reagent for polysaccharide special color development is positive, and the phenol sulfuric acid reagent is positive for color development. The weight p...

Embodiment 2

[0027] Embodiment 2 The preparation of fig polysaccharide of the present invention

[0028] Take 100g of figs, add water, and extract 2 times for a total of 8 hours at a material-to-liquid ratio of 1:20 at a temperature of 75°C; the process of separating fig polysaccharides by ethanol precipitation is as follows: when the concentration ratio is 1:1, add ethanol to a final concentration of 60 % Precipitation 20h. After the precipitate was obtained, it was freeze-dried and stored in a refrigerator at 4°C. Dissolve 5 mg of the dried precipitate in 50 mL of distilled water, and the anthrone sulfate reagent for polysaccharide special color development is positive, and the phenol sulfuric acid reagent is positive for color development.

Embodiment 3

[0029] Embodiment 3 The preparation of fig polysaccharide of the present invention

[0030] Take 100g of figs, add water, and extract 2 times for a total of 4 hours at a material-to-liquid ratio of 1:16 at a temperature of 85°C; the process of separating fig polysaccharides by ethanol precipitation is as follows: when the concentration ratio is 1:1, add ethanol to a final concentration of 60 % Precipitation 16h. After the precipitate was obtained, it was freeze-dried and stored in a refrigerator at 4°C. Dissolve 5 mg of the dried precipitate in 50 mL of distilled water, and the anthrone sulfate reagent for polysaccharide special color development is positive, and the phenol sulfuric acid reagent is positive for color development.

Abstract

The invention provides an application of fig polysaccharide in preparing immune modulators for fishes. The invention also provides an immune modulator for fishes, which is prepared by taking an effective amount of fig polysaccharide as an active component and adding acceptable auxiliary materials or auxiliary components. The experiment proves that the fig polysaccharide has a capacity of non-specific immune modulation for scale fishes; the consumption of the fig polysaccharide accounts for 0.1-0.8%w / w of the weight of auxiliary materials, and the fig polysaccharide has stronger efficacy of immune modulation; and the effect is optimal when the consumption of the fig polysaccharide is 0.4% of the weight of auxiliary materials. In addition, the immune modulator for fishes of the invention is a polysaccharide substance which has good safety, simultaneously is a carbohydrate which can save the consumption of carbohydrates in feed; especially, being a feed additive for fishes, the immune modulator for fishes has good effect and easy acquisition of materials, is safe and effective, and can save the cost.

Description

technical field [0001] The present invention relates to a new application of fig polysaccharide, in particular, the application of fig polysaccharide in preparing an immunomodulator for fish. Background technique [0002] Plant polysaccharide is a kind of biologically active polysaccharide. It has been confirmed by a large number of studies that polysaccharide compounds have unique functions such as strengthening non-specific immunity, anti-tumor, anti-virus, anti-inflammation, and anti-coagulation of human and animal bodies (such as mice and birds). , and the toxicity is small, and its immune function has been paid more and more attention. Foreign experts have conducted some research, but the research on plant polysaccharides in aquatic animals in my country is still very little, not systematic, and not comprehensive. Therefore, screening out a plant polysaccharide that has a good effect on the immune function of aquatic animals is of great significance to the scientific bre...
