Embodiment 1

[0024] a, get Flos Osmanthus fragrans, add 15 times of mass percentage concentration and be 75% ethanol extraction 3 times, extract 2 hours each time, filter, concentrate, obtain concentrated solution; Wherein, the weight of gained concentrated solution is 60% of Flos Osmanthus fragrans weight;

[0025] b. Cool the concentrated solution to room temperature, take the weight of the concentrated solution as a basis, add 4 times the amount of ethanol with a mass percentage concentration of 85% for alcohol precipitation, leave it for 6 hours, filter, and concentrate to obtain the effective components of Osmanthus fragrans .

Embodiment 2

[0027] a, get Flos Osmanthus fragrans, add 20 times of mass percent concentration and extract 2 times with 75% ethanol, extract for 1 hour each time, filter, concentrate to obtain concentrated solution; wherein, the weight of the obtained concentrated solution is 55% of Flos Osmanthus fragrans weight;

[0028] b. Cool the concentrated solution to room temperature, take the weight of the concentrated solution as a basis, add 4 times the amount of ethanol with a mass percentage concentration of 80% to carry out alcohol precipitation, leave it for 8 hours, filter, and concentrate to obtain the effective components of Osmanthus fragrans . Wherein, phenoxyethanol is added to the effective components of the osmanthus fragrans, and the amount of phenoxyethanol added is 0.5% by weight of the effective components of the osmanthus fragrans.

Embodiment 3

[0030] a, get Flos Osmanthus fragrans, add 8 times of mass percentage concentration and be 70% ethanol extraction 3 times, extract 3 hours each time, filter, concentrate, obtain concentrated solution; Wherein, the weight of gained concentrated solution is 58% of Flos Osmanthus fragrans weight;

[0031] b. Cool the concentrated solution to room temperature, take the weight of the concentrated solution as a basis, add 6 times the amount of ethanol with a mass percentage concentration of 70% for alcohol precipitation, leave it for 4 hours, filter, and concentrate to obtain the effective components of Osmanthus fragrans . Add phenoxyethanol to the effective components of the golden osmanthus, and the added amount of the phenoxyethanol is 0.1% of the weight of the whole active component of the golden osmanthus.

Abstract

The invention relates to a preparation method and applications of osmanthus fragrans efficient components, belonging to the field of extracting traditional Chinese medicine effective components. The preparation method comprises the following steps: a. taking osmanthus fragrans, adding ethanol for extraction, filtering, and concentrating to obtain concentrated liquor; and b. cooling the concentrated liquor to room temperature, adding ethanol with the mass percentage concentration of 80%-95% for alcohol precipitation, standing, filtering and concentrating to obtain osmanthus fragrans effective components. The preparation method and applications have the beneficial effects that the preparation method is simple and feasible, and capable of effectively retaining the effective components in the osmanthus fragrans. The effective components are safe to use, mild to act, have the activities of being antioxidized, anti-aging, skin-protective, are capable of delaying the skin aging, and can be used as an additive of food, health-care products, cosmetics and drug products, or as raw materials.

Description

technical field [0001] The invention belongs to the field of extraction of effective components of traditional Chinese medicines, and in particular relates to a preparation method and application of effective components of osmanthus fragrans. Background technique [0002] Osmanthus fragrans is an evergreen shrub or small tree family, with opposite leaves, mostly oval or oblong, with smooth, leathery leaves, serrated leaf edges, and clustered flowers. The flowers are pungent and can be used as medicine. It has the effects of reducing phlegm, relieving cough, promoting body fluid, and relieving pain. Because of its fragrant and long-lasting taste, it is often used to make pastries, candies, etc. [0003] However, there are few reports on the research of osmanthus osmanthus, which greatly restricts the application of osmanthus osmanthus. Contents of the invention [0004] The object of the present invention is to provide a preparation method and application of effective co...
