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
The present invention relates to a kind of preparation method of extract of natural plants, particularly relate to a kind of preparation method of Flos Rosae Rugosae extract.
Background technology
Containing 300 various chemical components in Flos Rosae Rugosae, as the alcohol of fragrance, aldehyde, fatty acid, phenol and containing the oil of essence and fat, to wake up stomach with easing the affected liver in normal food Flos Rosae Rugosae goods, have a respite and invigorate blood circulation, looks improving and the skin nourishing, make us refreshing refreshing.The flower opened at the beginning of Flos Rosae Rugosae can be used as medicine, and regulates the flow of vital energy, invigorates blood circulation, Thyme Extract, cures mainly menoxenia, and traumatic injury, irritability are had a stomachache, the diseases such as newborn too fat to move pain.Therefore extremely the liking of modern female.Therefore Flos Rosae Rugosae has a large amount of uses in medicine and food, therefore there is large-area plantation in the China that is planted in of Flos Rosae Rugosae, the use of present Flos Rosae Rugosae is master mainly with direct Rose Blume Getrocknete alabastrum, Rose Blume Getrocknete alabastrum belongs to frangible medical material, plantation family also needs a large amount of costs in storage and transport after Flos Rosae Rugosae results, in order to save storage and freight charges expense, Flos Rosae Rugosae can be processed into extract, be beneficial to and store and transport, and be more conducive to the quality control of Flos Rosae Rugosae in using as medicine and food.At present, the many employings of extracting mode of Flos Rosae Rugosae extract directly add water heating extraction, and extracting solution concentrates, finally extractum or continue dry dry powder.The extract that this method obtains, loses the original color and luster of Flos Rosae Rugosae and fragrance after dilution, and easy heavy metals exceeding standard, cannot ensure quality and the quality of Flos Rosae Rugosae extract.
Summary of the invention
The object of this invention is to provide a kind of preparation method of Flos Rosae Rugosae extract.
The object of the invention is to be achieved through the following technical solutions:
A kind of Flos Rosae Rugosae extracting method, is characterized in that this extracting method comprises the following steps:
Step 1: Flos Rosae Rugosae is weighed, dry, pulverize, with the 90-95% ethanol percolation of 4 times amount, the refining hydrochloric acid of ethanol adjusts PH to 4-5, diafiltration is ethanol flow velocity is 180-220ml/ minute, diafiltration 3-4 hour, get ethanol and consider liquid, medicinal residues retain, ethanol considers liquid decompression recycling ethanol to without alcohol taste, obtains concentrated solution 1 and keeps in;
Step 2: Flos Rosae Rugosae medicinal residues add the water of 8 times amount, boils 1 hour, and extract 2 times, merging filtrate, filtrate is cooled to less than 40 DEG C, obtains filtrate 2;
Step 3: by chelate resin post on filtrate 2, flow speed control is at 800-1000L/h, feed liquid in resin cements out by the sodium chloride solution that upper prop terminates rear use 7%, collect effluent, when the amount of collection effluent reaches the amount of filtrate 2, stop collecting, effluent reclaim under reduced pressure, concentrated solution specific gravity control surveys 1.08-1.1 in heat, obtains concentrated solution 2;
Step 4: carry out spraying dry after concentrated solution 1 and concentrated solution 2 being mixed, control inlet temperature 190-210 DEG C, leaving air temp 80-100 DEG C, obtains Flos Rosae Rugosae extract.
Preferably, use 93% ethanol percolation of 4 times amount in step 1, the refining hydrochloric acid of ethanol adjusts PH to 4.5, and during diafiltration, ethanol flow velocity is 200ml/ minute, diafiltration 3.5 hours.
Advantage of the present invention:
1. the Flos Rosae Rugosae extract extraction ratio that the preparation method in the present invention obtains is high, and extraction ratio is greater than 15%, and the Flos Rosae Rugosae extract of preparation has original color and luster and the fragrance of Flos Rosae Rugosae, and content of beary metal is all lower than the Chinese medicine extract content of beary metal standard of States Pharmacopoeia specifications.
2. in this preparation method, first raw material Flos Rosae Rugosae ethanol extraction, then use water extraction, fully can extract the fat-soluble and water soluble ingredient in Flos Rosae Rugosae, pigment particularly in Flos Rosae Rugosae and volatilization wet goods liposoluble constituent, farthest retain color and luster and the fragrance of Flos Rosae Rugosae.
3. in this preparation method, chelating resin post on the water extract of Flos Rosae Rugosae, can remove the heavy metal of rose wate extract majority, significantly reduces the content of the heavy metal in extract.
4. the Flos Rosae Rugosae extract of extracting method extraction of the present invention, have storage convenient transportation, content of beary metal is low, quality safety is controlled, at utmost keeps Flos Rosae Rugosae color and luster fragrance and the sufficient feature of extracts active ingredients.
