Problems solved by technology

[0005] In 2013, SFDA and the National Ministry of Health designated roses as a new resource food, which made the use of roses more widely. However, at present, the research and patents on roses are only limited to the extraction of rose essential oil, and there is no research on the extraction of rose essential oil. Put forward constructive suggestions on the disposal of residues, resulting in the loss of many active ingredients
For example, a preparation method for supe

Embodiment 1

[0032] A method for simultaneously extracting rose essential oil, pigments and flavonoids from roses, comprising the following steps:

[0033] Step (1), preparation of rose essential oil:

[0034] Add 10 times the mass of salt water with a mass concentration of 10% to the rose, and use steam distillation after immersion for 3 days. Distillation can be stopped when there is no fragrance in the output liquid or no oil drops appear when the condensate is dropped on the glass plate; the distillate is cooled, separated into layers, and the upper layer is taken, which is rose essential oil, which is stored in a refrigerator at 3°C;

[0035] Step (2), preparation of rose extract:

[0036] Filter the material in the distillation still after step (1), take the filter residue, and carry out reflux extraction with a mixture of 0.1mol / L hydrochloric acid and 70% ethanol. In the mixture, 0.1mol / L hydrochloric acid and 70% The volume ratio of ethanol is 1:1000, the extraction temperature ...

Embodiment 2

[0042] A method for simultaneously extracting rose essential oil, pigments and flavonoids from roses, comprising the following steps:

[0043] Step (1), preparation of rose essential oil:

[0044] Add 50 times the mass of salt water with a mass concentration of 15% to the rose, and use steam distillation after immersion for 5 days. Distillation can be stopped when there is no fragrance in the liquid or no oil drops appear when the condensed liquid is dropped on the glass plate; the distillate is cooled, separated into layers, and the upper layer is taken, which is rose essential oil, which is stored in a refrigerator at 4°C;

[0045] Step (2), preparation of rose extract:

[0046] Filter the material in the distillation still after step (1), take the filter residue, and carry out reflux extraction with a mixture of 0.1mol / L hydrochloric acid and 70% ethanol. In the mixture, 0.1mol / L hydrochloric acid and 70% The volume ratio of ethanol is 1:1000, the extraction temperature i...

Embodiment 3

[0052] A method for simultaneously extracting rose essential oil, pigments and flavonoids from roses, comprising the following steps:

[0053] Step (1), preparation of rose essential oil:

[0054] Add 30 times the mass of salt water with a mass concentration of 13% to the rose, and use steam distillation after immersion for 34 days. Distillation can be stopped when the effluent has no fragrance or the condensed liquid drops on the glass plate and no oil drops appear; the distillate is cooled, layered, and the upper layer is taken, which is rose essential oil, which is stored in a refrigerator at 3.5°C;

[0055] Step (2), preparation of rose extract:

[0056] Filter the material in the distillation still after step (1), take the filter residue, and carry out reflux extraction with a mixture of 0.1mol / L hydrochloric acid and 70% ethanol. In the mixture, 0.1mol / L hydrochloric acid and 70% The volume ratio of ethanol is 1:1000, the extraction temperature is 55°C, the extraction ...

Abstract

The invention relates to a method for extracting rose essential oil, pigment and rose glucoside from roses simultaneously and application of extracts and belongs to the technical field of medicine and chemistry. According to the method, essential oil, flavone and red pigment are extracted from roses in the same production process by means of phytochemical separation so as to achieve the purpose of total-effect utilization; roses are preserved and fermented by NaCl, so that the guarantee period of the roses is prolonged, the fragrance is permanent, and the extraction ratio of rose essential oil is improved; and the rose essential oil, pigment and flavone extracted according to the method can be applied to various fields such as foods, household chemicals and health-care products, have a wide application range, are purely natural, can be eaten directly, have high safety and are easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and in particular relates to a method for simultaneously extracting rose essential oil, pigment and rosein from roses and an application of the extract. Background technique [0002] Rose( Rosa rugosa Thunb.), Rosaceae Rosa is a deciduous shrub with beautiful flowers, color, fragrance and shape, and has extremely high economic value. Known as the "Golden Flower". Rose essential oil is the crown of flower oils, with elegant, soft, delicate, sweet and honey-like fragrance of roses. The fragrance is very strong, and two drops can be made into a high-end perfume. It is expensive and has the reputation of "liquid gold". Rose essential oil is mostly used in food, brewing wine, smoking tea, and deploying high-end essences. The extraction methods of rose oil mainly include steam distillation, extraction and supercritical fluid extraction. Soak the roses with 10-15% salt, on t...
