Problems solved by technology

[0003] Studies have shown that Rosa roxburghii is rich in superoxide dismutase, 18 kinds of amino acids, glucose, various alcohols, flavonoids, acids and other compounds, which have excellent anti-inflammatory, anti-allergic, anti-aging, improving skin vitality and anti-inflammatory properties. Oxidation and other activities, but the existing thorn pear extraction process is difficult to extract a variety of active ingredients of thorn pear, different active ingredients are extracted by different methods, and the filter residue is usually discarded, resulting in waste of thorn pears, but also increases the cost

Embodiment 1

[0022] A preparation method of Rosa roxburghii extract, prepared according to the following method:

[0023] S1. Raw material processing: wash the Rosa roxburghii, remove the core, and chop to obtain broken Rosa roxburghii; set aside;

[0024] S2. Juicing: the crushed prickly pears obtained in step S1 are squeezed through a double-screw press to obtain a first-pressed juice; Press the juice for the second time to obtain the pressed juice, and retain the solid residue after pressing the juice;

[0025] S3. Supercritical fluid extraction: add the solid residue obtained in step S2 to a supercritical fluid extraction tank, add CO 2 Solvent, preheat to 20°C, stir evenly, reduce the pressure, reduce the pressure to less than 7MPa, adjust the temperature, adjust the temperature to about 30°C, and reduce the solvent containing the extract to less than CO 2 Below the critical pressure, due to CO 2 The solubility is extremely reduced, and the extract and CO are separated by a separat...

[0030] S2. Juicing: the crushed prickly pears obtained in step S1 are squeezed through a double-screw press to obtain a first-pressed juice; Press the juice for the second time to obtain the pressed juice, and retain the solid residue after pressing the juice;

[0031] S3. Supercritical fluid extraction: add the solid residue obtained in step S2 to a supercritical fluid extraction tank, add CO 2 Solvent, preheat to 20°C, stir evenly, reduce the pressure, reduce the pressure to less than 7MPa, adjust the temperature, adjust the temperature to about 30°C, and reduce the solvent containing the extract to less than CO 2 Below the critical pressure, due to CO 2 The solubility is extremely reduced, and the extract and CO are separated by a separat...

Embodiment 3

[0034] A preparation method of Rosa roxburghii extract, prepared according to the following method:

[0035] S1. Raw material processing: wash the Rosa roxburghii, remove the core, and chop to obtain broken Rosa roxburghii; set aside;

[0036] S2. Juicing: the crushed prickly pears obtained in step S1 are squeezed through a double-screw press to obtain a first-pressed juice; Press the juice for the second time to obtain the pressed juice, and retain the solid residue after pressing the juice;

[0037] S3. Supercritical fluid extraction: add the solid residue obtained in step S2 to a supercritical fluid extraction tank, add CO 2 Solvent, preheat to 20°C, stir evenly, reduce the pressure, reduce the pressure to less than 7MPa, adjust the temperature, adjust the temperature to about 30°C, and reduce the solvent containing the extract to less than CO 2 Below the critical pressure, due to CO 2 The solubility is extremely reduced, and the extract and CO are separated by a separat...

Abstract

The invention provides a preparation method of a rosa roxburghii extract which is prepared according to the following method: S1, treating raw materials; S2, juicing; and S4, merging the juiced liquidobtained in the step S2 and the extract liquid obtained by the step S3, dialyzing to remove small-molecular saccharides and impurities, and concentrating to obtain the rosa roxburghii extract. Rosa roxburghii is extracted by combining juicing and supercritical fluid extraction, the method is simple and efficient, the extraction conditions are mild, and the components of the rosa roxburghii are guaranteed not to be destroyed, inactive impurity components and small-molecular saccharide substances with high viscosity are removed by dialysis purification treatment, and the obtained rosa roxburghii extract contains many kinds of active ingredients and has the advantages of good antioxidant, anti-allergic, anti-inflammatory and anti-aging activities, long shelf life, convenient storage and transportation, and broad application prospects.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an extract of Rosa roxburghii and its preparation method and application. Background technique [0002] Rosa roxburghii (Rosa roxburghii) is the fruit of the perennial deciduous shrub of the family Rosaceae. It is a rare fruit that grows in sunny hillsides, valleys, roadsides and bushes at an altitude of 500-2500m. [0003] Studies have shown that Rosa roxburghii is rich in superoxide dismutase, 18 kinds of amino acids, glucose, various alcohols, flavonoids, acids and other compounds, which have excellent anti-inflammatory, anti-allergic, anti-aging, improving skin vitality and anti-inflammatory properties. Oxidation and other activities, but the existing thorn pear extraction process is difficult to extract multiple active components of thorn pear, different active components are extracted by different methods, and the filter residue is usually discarded, resulting in the was...
