Embodiment 1

[0102] The steps for preparing the extract of the present invention are as follows:

[0103] 1), get 40g flat hazel leaf powder, 20 mesh;

[0104] 2), the extraction raw material is crushed, and 10% ethanol is used as the extraction solution, and the extraction is refluxed at 90° C. to obtain the extract (in this extraction step, the solid-liquid ratio of the reflux extraction is 1:5, and the extraction is performed 3 times, each extraction for 2 hours);

[0105] 3), the extract of step 2) is purified by a macroporous resin, and the macroporous resin is first eluted with water until the outflowing liquid is colorless, then eluted with 60% ethanol as the eluent, and passed through the FRAP method Detecting and collecting fractions eluted from the eluent, the macroporous adsorption resin is HPD-100;

[0106] 4), evaporate and recover the solvent of the eluted fraction, and dry to obtain final product.

[0107] After calculation and determination: the yield is 3.85%; the total...

Embodiment 2

[0109] The steps for preparing the extract of the present invention are as follows:

[0110] 1), get 40g hazel leaf powder, 80 mesh;

[0111] 2), the extraction raw material is pulverized, and 30% ethanol is used as the extraction solution, and reflux extraction is performed at 50° C. to obtain an extract (in this extraction step, the ratio of solid to liquid for reflux extraction is 1: 2, and the extraction is performed twice, each extraction for 3 hours);

[0112] 3), the extract of step 2) is purified by a macroporous resin, and the macroporous resin is first eluted with water until the outflowing liquid is colorless, then eluted with 65% ethanol as the eluent, and passed through the FRAP method Detect and collect the fractions eluted from the eluent, the macroporous adsorption resin is HPD-700;

[0113] 4), evaporate and recover the solvent of the eluted fraction, and dry to obtain final product.

[0114] After calculation and determination: the yield is 2.65%; the total ...

Embodiment 3

[0116] The steps for preparing the extract of the present invention are as follows:

[0117] 1), get 40g flat hazel leaf powder, 40 mesh;

[0118] 2), the extraction raw material is crushed, and 20% ethanol is used as the extraction solution, and the extraction is refluxed at 70°C to obtain the extract (in this extraction step, the ratio of solid to liquid for the reflux extraction is 1:10, and the extraction is performed twice, each time extraction for 1 hour);

[0119] 3), the extract of step 2) is purified by a macroporous resin, and the macroporous resin is first eluted with water until the outflowing liquid is colorless, then eluted with 50% ethanol as the eluent, and passed through the FRAP method Detect and collect the fractions eluted from the eluent, the macroporous adsorption resin is HPD-400;

[0120] 4), evaporate and recover the solvent of the eluted fraction, and dry to obtain final product.

[0121] After calculation and determination: the yield is 6.72%; the...

In the invention, the kind and the proportioning dose of the auxiliary materials and the main drug in the composition are reasonable and the composition has the advantages of stability and safety, quick results, high bioavailability, little side effect, little administration dose, convenience for drug administration and the like. The preparation method provided by the invention has the characteristics of simple process, easiness in controlling and stable product quality.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a composition of hazel leaf extract and a preparation method thereof, in particular to a composition made of hazel leaf extract that can be used for anti-aging and anti-oxidation, such as oral liquid or soft capsule, and a preparation method thereof . Background technique [0002] Antioxidant substances (antioxidants) refer to a class of substances that can scavenge oxygen free radicals, inhibit or eliminate and slow down oxidation reactions. The development and research of antioxidants has always been widely concerned by people, especially when scientists discovered that the disease and aging of organisms are the result of free radicals in organisms, the research of antioxidants has a broad space for development. Antioxidants can be derived from organisms, including animals, plants, microorganisms, etc., which are usually called natural antioxidants or biological oxidants; some antioxidan...
