Problems solved by technology

[0003] In order to solve the problem that various effective components with high content in the volatile oil of Schisandra chinensis cannot be further effectively separated and purified, and its purification cost is high and the practicability is poor (only methods such as GC-MS can be used for component detection, and effective separation cannot be achieved. Especially for technical problems such as industrialized separation and purification), the present invention provides a method for extracting active ingredients in Schisandra volatile oil by using low-temperature evaporation molecular distillation technology, which can quickly and effectively further separate and purify Schisandra volatile oil, extract The different components of Schisandra are used in different health foods and pharmaceutical products according to their functions, which increases the medical value of Schisandra chinensis

Abstract

The invention relates to a method for extracting schisandra volatile oil with borneol serving as a principal component through low temperature evaporation and belongs to the technical field of schisandra purification. According to the method, a molecular distillation device is used for performing first-stage molecular distillation on schisandra volatile oil which is obtained with a supercritical carbon dioxide extraction method sequentially, wherein the conditions for the first-stage molecular distillation is that the distillation temperature is 80 DEG C, the pressure ranges from 500 Pa to 10000 Pa, and the rotation speed of a film wiping motor is 245 revolutions per minute. Finally the borneol and the like are obtained, and the schisandra volatile oil is purified. The method can rapidly and effectively purify the schisandra volatile oil, the purification cost is reduced, medical and medicinal values of schisandra are increased, and the technology is energy-saving and environment-friendly.

Description

Technical field [0001] The present invention relates to the technical field of schisandra volatile oil purification, in particular to a method for purifying schisandra volatile oil by using molecular distillation technology of low-temperature evaporation. Background technique [0002] Schisandra has obvious sedative effect in the central nervous system, expands blood vessels in the cardiovascular system, improves myocardial metabolic enzyme activity, improves myocardial nutrition and function, and its volatile components have anti-oxidant and anti-convulsant effects. At present, there are few domestic studies on schisandra volatile oil. The existing method of separation and purification of schisandra volatile oil is atmospheric distillation, which has low purification rate and high energy consumption. Many medical ingredients cannot be effectively purified, resulting in increased purification costs and high prices for schisandra volatile oil. , Poor practicability, especially for...
