The invention discloses a method for synthesizing salicylic acid and derivatives thereof by multi-enzyme cascade catalysis of phenol, which comprises the following steps: reacting a reaction system containing phenol, enzyme, metal ion salt and bicarbonate to obtain salicylic acid and derivatives thereof; when the enzyme is carboxylase, the reaction system reacts to obtain salicylic acid; when the enzyme is a combination of carboxylase, carboxylate reductase, formate dehydrogenase and phosphokinase, the reaction system reacts to obtain salicylaldehyde; when the enzyme is a combination of carboxylase, carboxylate reductase, formate dehydrogenase, phosphokinase and alcohol dehydrogenase, the reaction system reacts to obtain salicyl alcohol; when the enzyme is a combination of carboxylase, carboxylate reductase, formate dehydrogenase, phosphokinase, alcohol dehydrogenase and glycosyltransferase, the reaction system reacts to obtain salicin. According to the method, a green synthesis path based on biological catalysis is utilized, phenol is converted into chemicals with higher economic value, and environmental pollution and carbon emission are reduced.

The invention belongs to the technical field of soil chemical analysis, and relates to a method for determining intracellular beta-glucosidase in acid soil, which comprises the following steps: 1) preparing a reagent for a chloroform fumigation method, a reagent for a salicin colorimetric method and a phosphate buffer solution; 2) pre-culturing the soil sample to be tested; 3) dividing the test soil samples into a fumigation group and a non-fumigation group, and performing chloroform fumigation treatment on the fumigation group; 4) respectively adding a phosphate buffer solution and a salicin colorimetric method reagent into the test soil sample in the unfumigated group and the test soil sample subjected to chloroform fumigation treatment, and culturing; (5) respectively measuring the light absorption values of the test soil sample of the non-fumigated group and the test soil sample of the fumigated group at 510nm of the spectrophotometer and the salicin concentration of the test soil sample; 6) calculating the intracellular beta-glucosidase based on the salicyl alcohol concentration. The method for determining the intracellular beta-glucosidase in the acid soil, provided by the invention, is convenient to operate, high in accuracy and high in feasibility.

The invention belongs to the technical field of medicines, and particularly relates to application of salicin in preparation of a preparation for preventing and / or treating bone marrow adipogenesis related diseases. The invention provides an application of salicin in preparation of a preparation for preventing and / or treating bone marrow adipogenesis related diseases. The bone marrow adipogenesis related diseases comprise osteoporosis. Research finds that salicin with a proper dose specifically blocks adipogenic differentiation of mesenchymal stem cells by inhibiting apoptosis of the mesenchymal stem cells and PI3K / AKT signal channels, and reduces BMAT accumulation to recover bone metabolism balance, so that bone marrow lipid metabolism can be effectively regulated, bone marrow adipogenesis related diseases such as osteoporosis can be prevented and / or treated, and the bone marrow adipogenesis related diseases can be prevented and / or treated. BMAT accumulation is reduced to restore bone metabolic balance.

The invention discloses an azelaic acid composite micelle composition as well as a preparation method and application thereof. The composition comprises the following components: azelaic acid, a component A, a component B and a pH regulator, the mass ratio of the azelaic acid to the component A to the component B is (0.5-6): (0.5-2): 1. When the azelaic acid composite micelle composition disclosed by the invention is in contact with skin, electrolyte in the skin can neutralize charges of shells of micelles, weaken electrostatic repulsion among the micelles and initiate micelle aggregation, the extrusion effect of the micelles in the aggregation process is enhanced, hydrophobic cores of part of micelle structures are broken, and thus the skin is protected. Meanwhile, beta-glucosidase in the skin can catalyze salicin in the component B in the micelle structure to be hydrolyzed into salicylic acid, and the salicylic acid and the azelaic acid cooperate with each other to jointly achieve the anti-inflammatory and oil-control effects.
