Problems solved by technology

However, the production equipment required by this method is expensive, the basic investment is high, the depreciation time of equipment is short, and the maintenance cost is also high; moreover, the operation pressure required by this method is high, dangerous, and energy consumption is high; in addition, the production capacity of this method is limited, and it is difficult to expand Produce
So supercritical CO 2 The production of volatile oil by extraction is costly and not suitable for larger batch production
In recent years, there are many literature reports on the preparation of volatile oil by microwave-assisted solvent extraction and ultrasonic-assisted solvent extraction. However, due to the limitation of equipment scale, it still stays in the small-scale operation of the laboratory, and at most it only reaches the pilot scale. Not suitable for mass production
[0006] The volatile oils extracted by solvents contain more non-volatile components, dark color, high viscosity, and poor quality when directly used as daily chemical raw materials; The quality is also poor, so it is necessary to refine the woody volatile oil

Abstract

The invention provides a preparation method of high-quality costus root oil, which comprises the steps as follows: using simply fried costus root as a raw material, percolating and extracting by low-class alcohol water solution with the volume concentration of 70-100%, depressurizing and concentrating the percolated solution, adjusting the alcohol content of the concentrated solution to 10-20%, extracting by petroleum ether or aether, depressurizing and concentrating the extracted solution, and refining the residue by a molecular distillation method. The yield rate of the costus root essential oil extracted by the method provided by the invention is high; the obtained costus root oil keeps chemical components of natural costus root essential oil, and is characterized by excellent smell and appearance quality with enriching main effective components such as costunolide and dehydrocostus lactone of the costus root.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a preparation method of high-quality balsamic oil. Background technique [0002] Yunmuxiang, also known as Guangmuxiang and Nanmuxiang, is a woody plant in the Compositae family. Aucklandia Lappa Dried roots of Decne. It is pungent and warm in nature, bitter in taste, and belongs to the spleen, stomach, large intestine, triple burner, and gallbladder meridian. It has the effects of promoting qi and relieving pain, invigorating the spleen and eliminating food. Wait. Modern pharmacological researches have proved that cloverwood has obvious pharmacological effects in choleretic, antidiarrheal, anti-inflammatory, antibacterial, anticonvulsant, gastric mucosal protection, and antitumor. [0003] The volatile oil of basilica is its main medicinal substance. For example, the main medicinal components of basilica and dehydrochondrolactone are the main components of its volatile oil....
