Embodiment 1

[0023] Weigh 10g each of the dried Codonopsis pilosula, grind them into millet-sized powders through a pulverizer, then add 90mL of 70% ethanol solution, stir and soak for 3 hours; then centrifuge at 2000r / min for 15min, and take the supernatant; then distill in a water bath at 80°C for 1 Remove the ethanol therein within 1 hour; finally adjust to 100ml with sterile distilled water, so that the final concentration is 10g of crude drug / 100ml of distilled water (that is, the quality of initially dried Codonopsis pilosula: 10 times its water quality). This step is followed by sterile packaging. If the amount of Codonopsis processed is large, it is only necessary to increase the corresponding material-liquid ratio proportionally, and the other parameters remain unchanged.

Embodiment 2

[0025] Weigh some dried Codonopsis pilosulae, grind them into millet-sized powder through a pulverizer, then add 70% ethanol solution according to the ratio of solid to liquid of 1:9 (that is, add 90mL ethanol to 10g Codonopsis pilosula powder), stir and soak for 1-12 hours; Then centrifuge at 1000r-3000r / min for 15min, take the supernatant; then distill in a water bath at 78°C-82°C for 1h to remove the ethanol; finally adjust it to 100-1000ml with sterile distilled water to make the concentration 1g-10g Crude drug / 100ml distilled water (that is, the quality of the first dried Codonopsis pilosula: 10-100 times its water quality). This step is followed by sterile packaging.

Embodiment 3

[0027] Weigh a number of dried Codonopsis pilosula, press out the oil through a press, then crush the residue into a powder with a size of 10-40 mesh, then add the oil and residue powder into 70% ethanol solution at a ratio of 1:9 to liquid, (i.e. 10g Codonopsis powder added to 90mL ethanol), using ultrasonic and microwave assisted extraction for 1-24 hours; then ultra-microfiltration, the filter hole diameter is 50umm, the supernatant is decolorized by activated carbon; then at 78°C-82°C Fractional distillation in a water bath for 1 hour to remove the ethanol; finally use sterile distilled water to adjust to 100-1000ml so that the concentration is 1g-10g of crude drug / 100ml of distilled water (that is, the quality of initially dried Codonopsis pilosula: 10-100 times its water quality ). This step is followed by sterile packaging.

Abstract

The invention discloses a codonopsis pilosula extractive capable of eliminating nitrite and a preparation method. The preparation method disclosed by the invention comprises the following steps of: crushing codonopsis pilosula, preparing ethanol leaching liquor, centrifuging supernate, distilling ethanol in a grading manner, and preparing and using hydrosolvent. The codonopsis pilosula extractive disclosed by the invention comes from natural raw materials; furthermore, codonopsis pilosula also has excellent antioxidation and immunological enhancement; and the codonopsis pilosula extractive has the advantages of being simple in operation process, short in production time, free from any additive and applicable to production and popularization.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and relates to a preparation method of a nitrite scavenger using Codonopsis pilosula as a raw material. Background technique [0002] Nitrite, crystals are white opaque granular, very similar to table salt in shape, it is not only a highly toxic substance (adults can cause poisoning if ingested 0.2-0.5 grams, 3.0 grams can cause death), but also a carcinogen. Industrial salt (also known as private salt) contains a large amount of nitrite; meat products are also allowed to use nitrite as a hair coloring agent in limited quantities. Therefore, the probability of food poisoning caused by illegal use of industrial salt and excessive addition of nitrite is higher. After oral administration of nitrite for 10 minutes to 3 hours, symptoms such as dizziness, chest tightness, palpitations, vomiting, and diarrhea may appear. In severe cases, loss of consciousness, coma, respiratory failure, and eve...
