Eucommia paste and preparation method thereof

Abstract

The invention relates to a eucommia paste and a preparation method thereof. The preparation method comprises the following steps of: cutting and placing eucommia leaves into a continuous countercurrent ultrasonic circulation extractor; adding purified water, wherein the weight of the purified water is 10 times larger than the weight of the eucommia leaves; extracting for 1 hour in a continuous countercurrent ultrasonic mode at extractive temperature of 40 DEG C; filtering through LSA-21 macroporous resin; eluting by using edible alcohol to obtain a eucommia extracting solution; mixing the eucommia extracting solution, spare sterilized honey, syrupus simplex, sodium benzoate and distilled water into a tank; heating for 40min at the temperature of 80 DEG C, wherein each 100ml of mixing solution contains 100mg of eucommia chlorogenic acid; and obtaining the eucommia paste. The process of the invention adopts a macroporous resin adsorbing and extracting technology, increases the contents of active components, reduces impurity content and product cost, increases product quality and shortens working hours.

Description

technical field [0001] The invention relates to a preparation method of eucommia paste and the eucommia paste. Background technique [0002] The extraction of active ingredients in general oral liquid solutions basically adopts decoction and ethanol extraction, which are traditional methods. There are many problems in practical application: first, the content of the main components is unstable; second, the clarity of the solution is unqualified, there are many impurities, the production process is time-consuming, labor-intensive, and the cost of pollution is easy to increase; third, it is easy to destroy heat-sensitive substances . The traditional production operation method has complex production process, long production working hours, large energy consumption, unstable content, and difficult to control the clarity of the solution. [0003] The extraction and separation of active ingredients is the most critical link in the production process of oral liquid solutions, and...

There are many problems in practical application: first, the content of the main components is unstable; second, the clarity of the solution is unqualified, there are many impurities, the production process is time-consuming, labor-intensive, and the cost of pollution is easy to increase; third, it is easy to destroy heat-sensitive substances

In recent decades, the old extraction process and equipment have basically been used up to now, without obvious reforms and breakthroughs, and the method of water extraction and alcohol precipitation to remove impurities is still very common, causing my country's plant extraction technology to lag behind the international industrial level
