The invention relates to a method for ultrasonic-enhanced extraction of a multicoloured leaf extract by using an ethanol and ethyl acetate cosolvent, and belongs to the technical field of chemical engineering and plant extraction. (2) synergistically degrading cellulose by using multi-component glycosidase; (3) cosolvent extraction; 4, chloroplast pigment is efficiently separated and purified, chlorophyll and other impurities in an extracting solution are effectively separated and removed through silica gel column chromatography, and therefore the high purity of the multicoloured leaf extract is achieved; according to the invention, ethanol and ethyl acetate are used as cosolvents to extract the multicoloured leaf extract, so that the extraction efficiency and the purity of the extract can be improved.

This invention relates to a high-entropy polymetallic organic framework-assisted reinforced magnesium hydride solid-state hydrogen storage material, which is composed of magnesium hydride and a high-entropy polymetallic organic framework in a mass ratio of 30-90:10-70, and its chemical formula is MgH. 2 -(FeCoNiCrMn) 3 O 4 The high-entropy multimetal-organic framework is composed of five different metal cations coordinated in an equimolar ratio; the metal cations are selected from cobalt, nickel, iron, chromium, and manganese. The material of this invention exhibits a high-entropy effect and possesses excellent thermodynamic properties and hydrogen storage cycle performance.

This invention belongs to the field of biomedical technology, specifically relating to a dissociation solution for aluminum adjuvant-adsorbed influenza vaccines and a method for determining antigen content. The dissociation solution of this invention is composed of potassium phosphate solution, diethanolamine, Triton X-100, Tween-20, dodecyl dimethyl betaine, and water. This dissociation solution exhibits excellent dissociation efficiency, achieving a recovery rate of 106%-110% for hemagglutinin from H1N1, H3N2, and BV influenza vaccines. It effectively protects antigen activity and is simple to operate with wide applicability. The dissociated sample can be directly used for mainstream detection methods such as one-way immunodiffusion assay, enzyme-linked immunosorbent assay, and high-performance liquid chromatography, enabling precise quantification of antigen content in aluminum adjuvant-adsorbed influenza vaccines and providing reliable technical support for vaccine quality control.

The invention relates to a releasing agent for detecting the folic acid content of a human body and application of the releasing agent, namely a treating fluid R1 is a mixed solution of sodium salicylate, guanidine isothiocyanate and tris (2-formylethyl) phosphine hydrochloride, effective denaturation dissociation can be carried out on protein within the pH value range of 5.0-7.0, the mixed solution can be stably stored, mild, efficient and sufficient dissociation is realized, and the content of folic acid in the human body is detected. The folic acid detection sensitivity is improved. The releasing agent is used in a corresponding immunodetection method so as to solve the technical problems that an existing product is complex in process or incomplete in releasing, poor in sensitivity and repeatability, unstable in treating fluid and unsatisfactory in sample comparison correlation. Through magnetic particle chemiluminescence detection, folic acid and a corresponding detection reagent and a detection method, the sensitivity and repeatability of the reagent and the comparison correlation of samples are better improved, the effect is ideal, and the performance reaches the level of international products. The process is more simplified, large-batch samples can be rapidly detected at high throughput, and clinical application is facilitated.
