Problems solved by technology

However, this extraction and separation method involves vacuum distillation and high vacuum rectification, which easily causes the oxidation reaction of β-elemene, which makes the process complicated, the preparation cost high, and the one-time separation efficiency low.
[0007] Therefore, in the extraction and separation

Embodiment Construction

[0024] In the prior art, in order to obtain high-concentration β-elemene, a combination of vacuum distillation and high-vacuum rectification is usually used to process the citronella oil by-product with low β-elemene concentration. Due to the need to use the two processing methods of vacuum distillation and high vacuum rectification, the processing technology is complicated, the preparation cost is high, and the one-time separation efficiency is low, which affects the preparation efficiency of high-concentration β-elemene.

[0025] Therefore, the present invention provides an extraction and separation method of β-elemene, an extraction and separation device thereof, and a preparation method of a silver nitrate surface-modified filler used in the extraction and separation method. According to the present invention, a method for extracting and separating β-elemene that is different from the combination of vacuum distillation and high vacuum rectification can be realized, which si...

Abstract

The invention relates to a method for extracting and separating beta-elemene, a device thereof and a method for preparing a filling thereof. The method for extracting and separating the beta-elemene provided by the embodiment of the invention comprises the steps as follows: the raw material of the beta-elemene is added to the upper end of a chromatography column, wherein, the chromatography column is provided with silver nitrate surface modification filling; eluent is added into the chromatography column to elute the mixed raw material of the beta-elemene and the filling; solution after the elution is collected at times; and silver ion in the solution which is collected at times after the elution is removed. In addition, the embodiment of the invention also provides the device used for extracting and separating the beta-elemene and the method for preparing the silver nitrate surface modification filling which is used in the method for extracting and separating the beta-elemene.

Description

technical field [0001] The present invention relates to the extraction and separation technology of β-elemene, in particular to an extraction and separation method of β-elemene and its extraction and separation device, and silver nitrate used in the extraction and separation method of β-elemene Preparation method of modified filler. Background technique [0002] Elemene is isolated from turmeric oil and citronella oil, and has been widely used in the treatment of cancer. The earliest application of anticancer drugs is to make Zedoary Oil Injection with Zedoary Oil. This injection can only be used to treat cervical cancer by taking local tumor administration. The course of treatment is long and the administration is inconvenient. This type of cancer cannot be effectively treated with this injection. In order to solve the problem of the limitation of the use of zedoary oil injection, people have separated elemene with fixed proportioning components from zedoary oil and citro...
