Embodiment 1

[0034] A scallion extract, the preparation method of which is:

[0035] (1) Clean the scallions;

[0036] (2) Freeze-drying the scallions cleaned in step (1) with a freeze dryer;

[0037] (3) The scallions cleaned in step (2) are pulverized with a pulverizer;

[0038] (4) adding an aqueous ethanol solution with a mass percentage concentration of 70% to the dried scallion powder in step (3) for soaking treatment;

[0039] (5) Control the temperature of the mixed solution obtained in step (4) to 50° C., power to 150 W, and frequency to ultrasonic conditions of 45 KHz for 30 minutes, then filter through a microporous membrane with a pore size of 0.45 μm, and collect the resulting filtrate;

[0040] (6) The filtrate obtained in step (5) was controlled to vacuum rotary evaporation under the condition of vacuum degree of 0.095 MPa to obtain the concentrated solution of Allium scallions extract, and the temperature was controlled to be -55°C for freeze-drying to obtain the Allium s...

Abstract

The invention provides an allium macrostemon extract and application thereof to antioxidation efficacy cosmetics. The allium macrostemon extract is characterized in that a preparation method comprisesthe steps of cleaning allium macrostemon; performing freeze drying and crushing; soaking obtained allium macrostemon powder by an ethanol water solution with the mass percent concentration being 60 to 80 percent; under the ultrasonic conditions that the temperature is 45 to 55 DEG C, the power is 140 to 160W and the frequency is 35 to 45KHz, ultrasonic treatment is performed for 25 to 35min; then, performing filtering by a microfiltration membrane with the hole diameter being 0.4 to 0.5mum; collecting filtering liquid; concentrating the obtained filtering liquid; performing freeze drying to obtain the allium macrostemon extract. The allium macrostemon extract has an antioxidation effect, so that when the allium macrostemon extract is used as an antioxidant to be applied to skin cosmetics,the antioxidation efficacy is achieved.

Description

technical field [0001] The invention belongs to the field of daily chemistry, and relates to a personal care product, in particular to a scallion extract and its application in cosmetics with antioxidant effect. Background technique [0002] Allium macrostemon or Allium chinensis is the bulb of Allium macrostemon or Allium chinensis in the Liliaceae family. It is mainly produced in China and has been widely cultivated as a medicinal and edible plant for thousands of years. Allium scallion is a traditional Chinese medicine in my country. It tastes bitter, pungent, warm in nature, and non-toxic. Traditional medicine believes that it has the effects of regulating qi, broadening the chest, unblocking yang and dispelling stagnation. Modern research shows that the main components of scallion are saponins and volatile oils. These ingredients may have anti-tumor, anti-bacterial, blocking nitrosamine synthesis and immune enhancement effects, which are closely related to cancer preve...
