Embodiment 1

[0057] Select 10kg of mature Rosa japonica fruit, wash it twice with deionized water, use a crusher to crush the fruit of Rosa japonica to a particle size of about 60 mesh, add 10 times the volume of deionized water, and extract it in a water bath at 80°C under normal pressure 2h, after the extraction, add 60% ethanol solution, extract in a water bath at 70°C under normal pressure for 2h, after the extraction, mix the extracts twice to obtain a mixed extract 1.

[0058] Select 10kg of mature Rosa cymbidium fruit, wash it twice with deionized water, use a crusher to crush the fruit of Rosa cymbidium to a particle size of 60 mesh, add 15 times the volume of deionized water, and extract it in a water bath at 80°C under normal pressure for 2 hours After the extraction, add 60% ethanol solution, extract in a water bath at 70° C. under normal pressure for 2 hours, and mix the extracts twice to obtain mixed extract II.

[0059] Mix the extract 1 and the extract 2 to obtain the total ...

Embodiment 2

[0078] Choose 10 kg of mature Rosa roxburghii fruit, wash 2 times with deionized water, use a crusher to crush the Rosa rostifolia fruit to a particle size of about 80 mesh, add 10 times the volume of 70% ethanol aqueous solution to extract 5 times in a 65°C water bath, and 5 The obtained filtrates of the second extractions were mixed to obtain a mixed filtrate. The combined filtrate was concentrated by evaporation under reduced pressure to remove ethanol therein. 1M sulfuric acid to adjust the pH value of the concentrated solution to 5, use AB-8 macroporous adsorption resin to absorb the concentrated solution for 2 hours, then use deionized water, 30% ethanol solution and 70% ethanol solution to elute the macroporous adsorption resin at a flow rate of 2BV / h. The mixed eluents were evaporated and concentrated under reduced pressure to remove the ethanol therein to obtain a concentrated solution, which was purified again by using ZTC-5 macroporous adsorption resin. The eluent...

Embodiment 3

[0100] Select 10 kg of mature Rosa cymbra fruit, wash it twice with deionized water, crush the fruit of Rosa cymbidium to a particle size of 60 mesh with a crusher, add 10 times the volume of deionized water, and extract in a water bath at 80°C at 1.2 MPa for 2 hours After the extraction, add 50% methanol solution, extract in a water bath at 70° C. at 1.2 MPa for 2 hours, and mix the extracts twice to obtain a mixed extract.

[0101] Evaporate and concentrate the extract under 5kPa and slight boiling conditions until the extract does not contain methanol to obtain a concentrate. After mixing equal volumes of 1M hydrochloric acid and 1M sulfuric acid, adjust the concentrated solution to pH=5, use AB-8 macroporous adsorption resin to absorb the concentrated solution at 25°C for 2 hours, and then use deionized water, 30% ethanol solution and 70% ethanol solution respectively The macroporous adsorption resin is eluted, and the flow rate of the eluent is 3BV / h. The eluate obtained...

Abstract

The invention discloses an extract of Rosa rosea. The rose fruit extract comprises any one or several combinations of saponins, rose fruit flavonoids and glucopyranosyl gallate, and these three substances account for 20% of the total weight of the rose fruit extract. -80%. The invention also discloses the preparation method and the application in cosmetics of the rose fruit extract. The Rosa rose fruit extract provided by the present invention, in addition to having significant anti-aging properties, can also significantly promote the secretion of type I collagen, and also has good moisturizing properties, whitening and anti-inflammatory properties, and can be used for cosmetics and / or skin care It is an ideal comprehensive cosmetic and / or skin care product additive.

Description

technical field [0001] The invention belongs to the field of biochemistry, and relates to an extract, a preparation method thereof and cosmetics containing the extract, in particular to an extract of rose fruit, a preparation method thereof and an application in cosmetics. Background technique [0002] Rosa davurica Pall. and Rosa maximowicziana Regel, commonly known as Rosa maximowicziana Regel, belong to the order Rosa and are small shrubs in the Rosaceae family. They are one of the higher plants in China. It is regarded as "special drug for treating scurvy" by European countries; it is known as "vitamin record holder". It is mainly distributed in the northeast of my country. Its fruit is also known as rosehip and rosehip. Folks eat it as a nutritious wild fruit in large quantities, and make it into fruit wine and tea. The taste of rose fruit is slightly sour and warm in nature. . The natural rose fruit grows in the northern primeval forests of Daxing'an Mountains and Xia...
