Preparation method for rose extract and cosmetic

The invention relates to a preparation method for rose extract. The preparation method comprises the following steps of: (a) mixing dry roseleaves or enzyme-inactivated fresh roseleaves with deionized water; regulating potential of hydrogen (pH) to 4.5-5.5; and grinding to obtain feed liquid; (b) adding the feed liquid obtained in the step (a) to an enzyme reactor; adding cellulase accounting for 0.02-0.05 percent of the weight of the feed liquid and pectinase accounting for 0.02-0.04 percent of the weight of the feed liquid; performing enzymolysis for 0.5-1.5 hours at the temperature of 45-50 DEG C at the pH of 4.5-5.5; and then, inactivating enzymes to obtain mixed feed liquid; (c) centrifuging the mixed feed liquid obtained in the step (b), and fetching supernate; (d) filtering the supernate by using a membrane to obtain filtrate; and (e) adding tea polyphenol to the filtrate, sterilizing and packaging. According to the preparation method for the rose extract, cell walls of the roses are broken by adopting the enzymolysis technology to enable active principles to be released from the cells, and moreover, the rose color and flavor are kept. Meanwhile, polysaccharide generated by proper enzymolysis also has a certain cosmetic effect. Moreover, the invention provides a cosmetic containing roseleaf and rose extracts and the tea polyphenol.

Biochemical joint preparation method and application of absolute rose oil

The invention provides a biochemical joint preparation method and application of absolute rose oil. The preparation method comprises the steps that coarse rose powder is prefermented by beta-glucosidase, amylase and cellulase to generate aroma, reflux extraction is conducted for 3-5 h with an aqueous solution the pH value is regulated to be 9-14, a Maillard reaction is conducted for 3-5 h, suction filtration is conducted, filtrate is retained, an ethanol solution is added into filter residues for secondary reflux extraction, suction filtration is conducted, filtrate is retained, the filtrates obtained in two times of suction filtration are mixed, concentration and alcohol precipitation are sequentially conducted, and a rose extract is obtained; the rose extract is purified through molecular distillation, light components are retained, heavy components are purified through molecular distillation again, the light components are mixed, and the purified absolute rose oil is obtained. The absolute rose oil has purer and richer aroma and fewer impurities, and the irritation is reduced. When the absolute rose oil is applied to reconstituted tobaccos, the color and luster of the reconstituted tobaccos is more natural and uniform, the aroma can be enriched, irritation and offensive odor can be reduced, and the sensory quality can be improved; when the absolute rose oil is applied to a novel tobacco product atomizing agent, the aroma is enriched, the noble rose note is improved, and the tobacco aroma is increased.

Method for preparing rose extracting solution, rose water taking rose extracting solution as active ingredient, and preparation method of rose water

The invention discloses a method for preparing a rose extracting solution, rose water taking the rose extracting solution as an active ingredient, and a preparation method of the rose water. The rose extracting solution is prepared by the following steps: taking rose as a raw material, performing water leaching distillation, collecting a gas phase part, condensing, concentrating and sterilizing. The method for preparing the rose extracting solution comprises the following steps: treating the raw materials, performing water leaching distillation and sterilizing. The rose water which takes the rose extracting solution as the active ingredient comprises 2-5 weight percent of rose extracting solution, 0.01-0.03 weight percent of flavoring agent and the balance of purified water; and the method for preparing the rose water which takes the rose extracting solution as the active ingredient comprises the steps of adding the rose extracting solution into water to be prepared according to a formula weight ratio, uniformly mixing, and sterilizing to obtain target rose water. By the adoption of the water leaching distillation, comprehensiveness of contained substances is guaranteed, and components of aroma volatile oil are kept; and moreover, the rose water is clean in aroma and elegant in taste, contributes to relieving the emotion, improving the internal secretion and relieving the feeling of fatigue without adding any coloring matter and preservative, is safe to drink, and is safe and reliable.

Application of rose extract in preparing anti-depression medicaments

The invention relates to application of a rose extract in preparing anti-depression medicaments, so as to effectively solve the problem of preparing anti-depression medicaments and realize application of a rose extract in preparing anti-depression medicaments. According to the application of the rose extract in preparing anti-depression medicaments, the rose extract is prepared by virtue of the following steps: drying and crushing rose flower into coarse powder; performing reflux extraction and degreasing by use of petroleum ether, and removing the petroleum ether liquid; volatilizing the petroleum ether from the degreased rose dreg, soaking with ethanol, and performing reflux extraction; decompressing the filtrate to reclaim ethanol until the liquid does not have ethanol smell, concentrating, and adding distilled water so as to disperse the concentrate; loading the dispersant on macroporous adsorption resin, eluting with distilled water, and removing the aqueous liquid; continuously eluting with ethanol, and removing the eluent; then eluting with ethanol, collecting the eluent, reclaiming ethanol in reduced pressure, drying and crushing. The rose extract has an anti-depression effect and can be used for effectively preparing anti-depression medicaments, so that the application of the rose extract in preparing anti-depression medicaments can be realized.
