Abstract
The invention discloses an extracting method of chrysanthemum essential oil, belonging to the technical field of chemical industries. With the adoption of the extracting method, the problems of excessive sediments and low purity in the extracting process of the chrysanthemum essential oil at present are solved; the oil yield of the chrysanthemum essential oil can be greatly improved; the impurity is reduced; and the chrysanthemum essential oil resource can be better used. The extracting method is characterized by comprising the following steps: carrying out dynamic leaching on the crushed chrysanthemum by petroleum ether; carrying out reflux extraction by ethyl acetate after petroleum ether is recovered from an extracting solution in a filtering manner; and concentrating the chrysanthemum liquid, adding water to dynamically extract; filtering, decompressing, concentrating, depositing in alcohol and purifying the extracting solution to obtain the chrysanthemum essential oil. The extracting process is simple and feasible, high in oil yield, and short in time, and is an ideal extracting method; and resources are saved, and no harmful substance is generated in the extracting process.
Description
Technical field
The present invention relates to a kind of extracting process of chrysanthemum essential oil, belong to chemical technology field.
Background technology
Chrysanthemum has the fabulous numerous effects such as heat, detoxifcation of reducing internal heat, drive, and chrysanthemum essential oil acetone equal solvent soluble in water, pure and mild is insoluble to sherwood oil, is slightly soluble in ethyl acetate.From extracting the method for chrysanthemum essential oil, mainly contain water extraction, water extract-alcohol precipitation and rare ethanol-extracted etc. at present.The processes such as concentrating and precipitating impurity elimination are all arranged, in this process, have precipitation capacity large, filter time consumption and energy consumption, the problem such as oil yield is low.
Summary of the invention
The objective of the invention is in order to disclose a kind of extracting process of chrysanthemum, simple for process, oil yield is high, the time is short, economize on resources, unharmful substance produces in leaching process, is a kind of desirable extracting process.
Technical scheme of the present invention: a kind of extracting process of chrysanthemum, its preparation technology is: (1) carries out dynamic lixiviate with the chrysanthemum of pulverizing with sherwood oil, after extracting solution reclaims sherwood oil after filtration; (2) carry out refluxing extraction with ethyl acetate again, concentrated chrysanthemum liquid adds water, dynamic extraction; (3) extracting solution through filtration, decompression, concentrated, alcohol precipitation, purifying, obtain chrysanthemum essential oil.
Beneficial effect of the present invention: extracting process of the present invention, too much in order to solve in the present chrysanthemum essential oil leaching process throw out, the problem such as purity is low.Can increase substantially the oil yield of chrysanthemum essential oil, impurity reduction uses the chrysanthemum essential oil resource better.This extraction process is simple, oil yield is high, the time is short, economize on resources, and unharmful substance produces in leaching process, is a kind of desirable extracting process.
Below in conjunction with embodiment, specify preparation technology of the present invention
Embodiment
