Abstract

The invention discloses a rose extraction method which comprises the following steps: weighing, drying and crushing rose, carrying out percolation for 3-4 h by 90-95% ethyl alcohol, wherein the PH of ethyl alcohol is adjusted to 4-5 by refined hydrochloric acid, taking ethyl alcohol filtrate, reserving herb residues, and recycling ethyl alcohol from filtrate at reduced pressure until the filtrate is free of alcohol smell so as to obtain a concentrated solution 1; adding water, the use amount of which is eight times of that of the rose residues, into the rose residues, boiling for 1 hour, extracting for two times, mixing filtrates, and cooling the mixed filtrate to 40 DEG C so as to obtain filtrate 2; enabling the filtrate 2 to be adsorbed on a chelating resin column, replacing material liquid in the resin with a 7% sodium chloride solution after filtrate 2 is completely adsorbed on the column, collecting effluent and recycling at reduced pressure so as to obtain a concentrated solution 2, wherein the specific gravity is controlled to be 1.08-1.11; and after the concentrated solution 1 and the concentrated solution 2 are mixed, spray-drying so as to obtain a rose extractive. The rose extractive extracted through the extraction method provided by the invention has the characteristics that storage and transportation are convenient, heavy metal content is low, quality is safe and controllable, colour, luster and fragrance of rose are retained to the greatest extent, and effective ingredients are extracted sufficiently.

Description

technical field [0001] The invention relates to a method for preparing natural plant extracts, in particular to a method for preparing rose flower extracts. Background technique [0002] Roses contain more than 300 kinds of chemical components, such as aromatic alcohols, aldehydes, fatty acids, phenols, and essential oils and fats. Rose products are often eaten to soften the liver and refresh the stomach, soothe qi and activate blood circulation, beautify the skin, and make people feel refreshed. The first flowers of roses can be used as medicine, which has the effects of regulating qi, promoting blood circulation, and astringent. Therefore, it is loved by modern women. Therefore, roses are widely used in medicine and food, so roses are planted on a large scale in our country. Now roses are mostly used directly as dried rose buds, which are fragile medicinal materials. After the roses are harvested, growers still need a lot of cost in storage and transportation. In order t...
