Embodiment 1

[0013] In the present embodiment, cyclic adenosine monophosphate is extracted with Xinjiang gray jujube as the extraction raw material, and the method is as follows:

[0014] Weigh 100g of Xinjiang gray jujube, wash it with water, add 1.5kg of water, and homogenize it with a homogenizer, set the speed of the homogenizer to 13000r / min, and the homogenization time is 2min; Microwave treatment was carried out in the microwave oven, the microwave power was set to 450W, and the microwave time was 90s, and then ultrasonic treatment was carried out in the ultrasonic machine, the set power was 120W, the treatment temperature was 60°C, and the treatment time was 30min; the jujube pulp after ultrasonic treatment was centrifuged for 20 Minutes, the centrifugal speed is 4200rpm, the supernatant is the first-grade cAMP extract, jujube dregs is added with water to prepare a 0.17g / ml sample liquid, and after extraction under the same conditions as above, it is centrifuged again, and the super...

Embodiment 2

[0016] Weigh 100g of Xinjiang chicken heart jujube, wash it with water, add 2.5kg of water, and use a homogenizer to homogenate, set the speed of the homogenizer to 10000r / min, and the homogenization time to be 4min; put the homogenized jujube pulp in a microwave oven Microwave treatment was carried out in the microwave oven, the microwave power was set to 650W, and the microwave time was 40s; then ultrasonic treatment was carried out in the ultrasonic machine, the set power was 150W, the treatment temperature was 70°C, and the treatment time was 20min; the jujube pulp after ultrasonic treatment was centrifuged for 20 minutes, the centrifugal speed is 4200rpm, the supernatant is the first-grade cAMP extract, and jujube dregs are added with water to prepare a 0.2g / ml sample solution. The extracts from the two treatments were combined, and the extracts were vacuum-concentrated at 65° C. and 0.095 MPa to obtain concentrated cyclic adenosine monophosphate products. It was determin...

Embodiment 3

[0018] Weigh 100g of Xinzheng Jixin jujube, wash it with water, add 1kg of water, and homogenize it with a homogenizer, set the speed of the homogenizer to 19000r / min, and homogenize for 7 minutes; Perform microwave treatment, set the microwave power to 800W, and microwave time to 180s; then perform ultrasonic treatment in an ultrasonic machine, set the power to 175W, process temperature at 90°C, and process time for 10 minutes; centrifuge the jujube pulp after ultrasonic treatment for 20 minutes , the centrifugal speed is 4200rpm, the supernatant is the first-grade cAMP extract, and jujube dregs are added with water to prepare a 0.06g / ml sample solution. The extracted solution treated twice is vacuum-concentrated at 65° C. and 0.095 MPa to obtain a concentrated product of cyclic adenosine monophosphate. It was determined that the extraction rate of cAMP in Xinzheng Jixinzao in this example was 169.27 μg / g.

Abstract

The invention discloses a method for extracting cyclic adenosine monophosphate from dates, which comprises: pulverizing dates, adding water, mixing into pulp, microwaving the data pulp under the microwave power of 150-900 W for 10-450 seconds, microwaving the data pulp at 20-100 DEG C under the microwave power of 100-250 W for 10-60 minutes, carrying out the solid-liquid separation on the data pulp, and concentrating the separated liquid to obtain the concentrated cyclic adenosine monophosphate. The method enables all points in the data pulp to get the same action by utilizing the high-energyfunction of microwaves and the cavitation of the ultrasonic vibrations, so as to reduce the bonding force of the cyclic adenosine monophosphate and the data substrate, shorten the extraction time andincrease the extraction rate. In the extraction process, water is used as an extractant and no harmful chemical reagent for assistant extraction is added, so that the method can not cause the environmental pollution. Meanwhile, the method has the advantages of simple extraction technique and high extraction rate, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for extracting cyclic adenosine monophosphate in jujube. Background technique [0002] The molecular formula of cyclic adenosine monophosphate (cAMP for short) is C 10 h 12 N 5 o 6 P·H 2 O, with a relative molecular weight of 347.23, is a non-specific small molecule highly bioactive substance that widely exists in organisms. It participates in physiological activities such as enzyme activity regulation, gene expression, cell proliferation and differentiation, and nutrient metabolism. An important regulator of metabolism, which has a significant effect on improving animal performance and carcass quality. Basic medical research has proved that at least 40 kinds of diseases (including major diseases such as cancer, hypertension, coronary heart disease, myocardial infarction and cardiogenic shock) are related to the metabolism of cAMP; clinical medical research has proved that cAMP can relax smooth muscle, dilate bloo...
