Problems solved by technology

However, the stability of the active ingredients in Osmanthus fragrans (verbacoside, salidroside, etc.) is poor, and prolonged heating may cause its quality to deteriorate, such as inactivation of active substances, deepening of color, generation of bad smell, and reduction of efficacy
In addition, the application of sweet-scented osmanthus extract usually only focuses on the content of a single functional component in the sweet-scented osmanthus extract, and does not pay attention to other functional components, resulting in a waste of resources

preparation example Construction

[0047] According to a first aspect of the present invention, a kind of preparation method of osmanthus fragrans extract is provided, comprising the following steps:

[0048] (a) mixing the pretreated osmanthus fragrans with a solvent and carrying out negative pressure extraction to obtain an extract;

[0049] The extract is subjected to solid-liquid separation to obtain a supernatant;

[0050] (b) Concentrating the supernatant and using an adsorption resin for adsorption, and then eluting to obtain an eluent;

[0051] The eluate is concentrated and freeze-dried to obtain the osmanthus extract containing verbascoside and salidroside.

[0052] Specifically, the pretreatment in step (a) of the present invention is to prepare the fresh osmanthus into a form suitable for extraction. Typical but non-limiting pretreatment steps may be, for example, drying and / or powdering.

[0053] Negative pressure extraction refers to the use of vacuum decompression during extraction, so that the...

Embodiment 1

[0097] The present embodiment provides a kind of preparation method of sweet-scented osmanthus extract, and technological process diagram is as follows figure 1 shown, including the following steps:

[0098](a) after drying, 1 kg of dried sweet-scented osmanthus obtained is mechanically pulverized, mixed with a solvent and subjected to negative pressure extraction to obtain an extract; wherein, the solvent is water, and the solid-liquid ratio of sweet osmanthus and solvent is 1:20, and the pressure of negative pressure extraction is -0.06MPa, the temperature of negative pressure extraction is 30°C, the time of negative pressure extraction is 60min, and the number of negative pressure extraction is 1 time;

[0099] centrifuging the extract to remove the precipitate to obtain a supernatant; the centrifugation speed is 3000r / min;

[0100] (b) after concentrating the supernatant, use D101 macroporous adsorption resin to adsorb, and then use water and 30% ethanol aqueous solution ...

Embodiment 2

[0103] This example provides a preparation method of sweet-scented osmanthus extract, except that the temperature of negative pressure extraction in step (a) is 40° C., other steps are the same as in Example 1.

Abstract

The invention provides a sweet-scented osmanthus extract, a preparation method thereof and cosmetics, and relates to the technical field of natural plant extraction. The preparation method comprises the following steps of mixing pretreated sweet-scented osmanthus with a solvent, carrying out negative pressure extraction, carrying out solid-liquid separation, concentrating a supernatant obtained by solid-liquid separation, carrying out adsorption and elution by adopting adsorption resin, concentrating the obtained eluent, and carrying out freeze drying to obtain the sweet-scented osmanthus extract. Negative pressure extraction is adopted, so that the boiling point of a mixed material formed by the sweet-scented osmanthus and the solvent is reduced, and therefore, effective components with thermosensitive properties in the sweet-scented osmanthus can be rapidly and effectively extracted at a relatively low temperature, and the activity of the effective components cannot be damaged; and the obtained eluent is concentrated and then freeze-dried, so that the concentration of active substances is retained to the maximum extent. The sweet-scented osmanthus extract prepared through the preparation method contains effective components such as verbascoside and salidroside at the same time, the content of the effective components is high, and the sweet-scented osmanthus extract is light in color and good in stability.

Description

technical field [0001] The invention relates to the technical field of natural plant extraction, in particular to an osmanthus fragrans extract, a preparation method thereof and cosmetics. Background technique [0002] Osmanthus fragrans is one of my country's top ten traditional famous flowers, and it is planted on a large scale in Guizhou and other areas. Studies have found that osmanthus is rich in verbascoside, salidroside and other active ingredients, and because osmanthus has a wide range of sources and low cost, osmanthus or osmanthus extracts can be used as raw materials for various products such as food and health products. [0003] Osmanthus fragrans extract is mainly extracted or processed from osmanthus fragrans. Different extraction methods make the active ingredients or contents contained in the sweet-scented osmanthus extract also different. In the existing osmanthus fragrans extraction technology (such as high-temperature extraction) research, often only fo...
