Abstract

The invention provides a method for extracting effective ingredients in amber through ultrasonic-assisted extraction and supercritical CO2 gradient elution, and belongs to an extraction technology adopting a high-strength and high-energy ultrasonic-assisted extraction and supercritical CO2 fluid gradient elution. The method comprises the steps as follows: the amber and inactive substances are mixed and added in a pulverizer and pulverized into a mixture; the mixture is added into an ultrasonic-assisted extraction device, ethyl alcohol is injected into the ultrasonic-assisted extraction device, the extraction temperature, time and energy frequency of the ultrasonic-assisted extraction device are set, an ethyl alcohol extract liquor is obtained and taken out, ethyl alcohol is recovered, and an extract is obtained; and the extract is added into a supercritical CO2 extraction device, pressure and temperature gradient change of the supercritical CO2 extraction device is set, and amber acid, abietic acid, d-pimaric acid and essential oil are extracted. Compared with the prior art, the method is simple to operate, safe, reliable, low in cost, energy-saving and environment-friendly, and meanwhile, the obtained amber product is high in purity, good in quality and applicable to preparation of drugs, food and drinks.

Description

technical field

[0001] The present invention belongs to ultrasonic extraction method and CO 2 Technical field of supercritical extraction method. In particular, it relates to a method of ultrasonic extraction assisted by CO 2 Supercritical extraction to obtain succinic acid, rosinic acid, pine resin and essential oils in amber. Background technique

[0002] Amber is a resin fossil formed by the resin of the Tertiary ancient coniferous plants from 30 million to 60 million years ago, which was covered and buried deep in the ground due to changes in the earth's crust, and was metamorphosed by formation pressure and heat. Traditional Chinese medicine believes that amber can be used as medicine. The three major functions of amber recorded in "Famous Doctors" written by Tao Hongjing in the Southern and Northern Dynasties are: one is to calm the mind, the other is to promote blood circulation and disperse stasis, and the third is to diuretic and relieve stranguria, especially the...
