Abstract

The invention relates to a method for extracting red date cyclic adenosine monophosphate through an ultrasonic composite membrane technology. The method solves the problem that the existing extraction technology has the defects of complex processes, low extraction rate, high industrialization difficulty and low product purity. The method comprises the following steps of removing date pits of cleaned red dates, crushing the red dates obtained by the previous step, adding an appropriate amount of an ethanol solvent into the crushed red dates, carrying out ultrasonic reinforcement extraction, repeatedly carrying out ultrasonic extraction of extracted filter residues, merging the extract obtained by the previous step, removing macromolecules of bacteria, proteins, pectin, polysaccharides and starch, and monosaccharides of glucose and fructose respectively through ultrafiltration and nanofiltration, intercepting cyclic adenosine monophosphate-rich concentrate, and carrying out pressure reduction condensation and spray drying to obtain 30% of a powdery cyclic adenosine monophosphate crude product. The method provided by the invention is easy for operation, is convenient for extraction, is fast, has short extraction time and a high cyclic adenosine monophosphate extraction rate, and is suitable for industrialized production. A product obtained by the method has high purity, is purely natural and does not produce chemical pollution. Therefore, the method provides an effective approach for comprehensive development of red date further processing.

Description

technical field [0001] The invention relates to a method for extracting and developing active ingredients in natural products, in particular to a method for extracting cyclic adenosine monophosphate from jujube by using ultrasonic composite membrane technology. Background technique [0002] Jujube is the fruit of Ziziphus Jujuba Mill, a plant belonging to the Rhamnaceae family. It is native to China and has a history of 5,000 years of artificial cultivation in my country. It has extremely high nutritional value and good medical care. In addition to a large amount of fructose and glucose, jujube also contains a certain amount of oligosaccharides and polysaccharides, rich in vitamin C, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), and a certain amount of amino acids, Nutrient elements such as vitamins and mineral elements, among which cyclic adenosine monophosphate is the highest content in known plants. Cyclic adenosine monophosphate (cAMP) i...
