Vacuum freeze-drying process for retaining medicative active components of traditional Chinese medicine of radix tetrastigme

Abstract

The invention discloses a vacuum freeze-drying process for retaining the medicative active components of a traditional Chinese medicine of radix tetrastigme, which comprises the following steps of: selecting a raw material of the radix tetrastigme, washing, slicing, predrying, loading with a tray, prefreezing, sublimating, drying and discharging after resolving and drying. The process adopts the reasonable configuration of the parameters of the time, the temperature, the pressure and the like of vacuum freeze-drying, thereby retaining the medicative active components furthest. The radix tetrastigme prepared by the process can furthest preserve the medicative components of an original medicine and reduces the properties of a crude medicine, the main anti-tumor component of general flavone is 3.6 times that of a traditional processing method, and saponin is 2.5 times that of the traditional processing method. By carrying out pulverization, physical wall breaking, discharge, dehumidification, packaging and sterilization on the radix tetrastigme after being resolved and dried by adopting the invention, an oral preparation which is an eating mode of the radix tetrastigme with best medicinal value can be prepared.

Description

technical field [0001] The invention relates to a drying process of traditional Chinese medicine, in particular to a vacuum freeze-drying process of Chinese medicine Clover. Background technique [0002] Clover is a plant of the grape family Tetrastigma hemsleyanum Diels et Gilg, also known as golden thread hanging gourd, stone mouse, silk thread hanging golden bell, snake monkshood, small flat rattan, and Tujing pill. [0003] Clover is a perennial herbaceous climbing vine, which is used as medicine with tubers or whole plants, and roots are rooted on the nodes of the ground part, and the tubers are ovate or oval. Born in the sparse forests of valleys or damp rock walls. The growth environment requirements are very peculiar, and it is only distributed in Zhejiang, Jiangxi, Fujian, Hubei and Southwest China. "Colorful Book of Materia Medica" contains that Clover contains starch, β-sitosterol, ergosterol, dandelion ketone, dandelion ketone, carotin, kaempferol, quercetin, ...

AI Technical Summary

Problems solved by technology

During the baking process, the essence is lost or destroyed, thereby significantly reducing the efficacy and active ingredients. What can not be ignored is that the sulfur fumigation method in the traditional processing of clover slices makes the moldy clover white and unrecognizable, so that the safety and quality cannot be guaranteed, let alone the efficacy and curative effect

Although this traditional clover processing method has been baked and dried and sulfur fumigated, its water content is high, it is easy to be moldy and moth-eaten, and it is not easy to store and utilize.

[0006] The method of taking decocted clover decoction pieces (traditionally processed) can only decoct 3% to 5% of the medicinal effect in water, and 95% of the ingredients are wasted , so that the precious Chinese medicine Clover can not be fully utilized

In the process of decoction, some of the properties of the medicine are volatilized, which greatly reduces the efficacy and active ingredients. Decoction of traditional Chinese medicine is not a convenient way to take traditional Chinese medicine

[0007] Clover as a rare plant, it has not yet been successfully cultivated artificially, and the wild resources are decreasing day by day. The essence of Yeqing is retained as much as possible and can be easily absorbed by the human body, the traditional processing technology of clover can no longer meet the requirements
