Abstract

The invention provides a method for efficiently preparing cycloastragenol. The method sequentially comprises the following steps of A, fermenting: filling total saponins of radix astragali seu hedysari into a fermentation tank, injecting a buffer solution containing compound enzyme into the fermentation tank until a sample is completely immersed, stirring and then performing catalytic fermentation; B, regulating alkali: after catalysis is ended, regulating fermentation liquid obtained in the step A into an alkali solution, and standing for one hour; C, performing counter-current extraction: pumping the fermentation liquid obtained in the step B and an extraction agent into a counter-current extraction tower for extracting; D, performing vacuum concentration on a mixed solution, which is obtained by extracting, of the cycloastragenol and the extraction agent. The method provided by the invention has the beneficial effects that firstly, a compound enzyme fermentation technology and a continuous counter-current extraction technology are combined for extracting and purifying to obtain high-purity cycloastragenol, and high conversion rate and higher purity of products are realized; secondly, the finishing time of the whole process does not exceed eight hours; the temperature is low in the operation process, so that biological activity of the cycloastragenol is guaranteed; the production efficiency is improved, energy consumption is reduced, and the production cost is reduced by 50 percent or above 50 percent.

Description

technical field [0001] The invention relates to the field of medicine and chemical industry, in particular to a method for efficiently preparing cycloastragenol. Background technique [0002] Cycloastragenol (CAG) is a tetracyclic triterpenoid cycloartane compound derived from the traditional Chinese medicine Astragalus, with a molecular formula of C30H50O5 and a relative molecular weight of 490.71. Cycloastragenol can promote the proliferation of lymphocytes through the activation of telomerase, thereby delaying the aging of cells. At present, CAG is used as an effective wound repair medicine and the only raw material of health care products that can activate telomerase to play an anti-aging effect on the market. It plays an irreplaceable role in the anti-aging product market and has broad market prospects. [0003] There are nearly 20 saponins isolated and identified in Astragalus membranaceus, most of which are cycloartane-type tetracyclic triterpene saponins. However,...
