Traditional Chinese medicine extraction technology to extract herb gynostemma process

by:Deyuan      2020-08-21
With the leap development of the centrifugal extraction technology, the centrifugal extraction solvent extraction has been widely applied to traditional Chinese medicine industry. Chinese medicine extraction technology is a modern pharmaceutical technology a new type of traditional Chinese medicine, it is through the net of medicinal materials or processed products by leaching, extraction, clarification, filtration, evaporation methods such as extraction, purification and made for the proprietary Chinese medicine production products of raw materials, has a broad market space, in many fields such as medicine, food, health care products, cosmetics, have been widely used, and thus led to a large number of relevant industries. This paper mainly introduces Chinese medicine extraction technology to extract the herb gynostemma process.

extraction to extract the gynostemma process experiment, dry gynostemma herbs smash into meal, weighing 100 g round bottom flask, repeatedly reflux extraction with 70% ethanol, extract, merger with rotary evaporator concentrate after decompression drying, drying with 1000 ml hot water dissolves, joined with the volume of petroleum ether extract 3 times, use water solution with the volume of water saturation of n-butyl alcohol extraction, repeatedly until n-butyl alcohol layer colorless, combination of n-butyl alcohol extract, with a rotary evaporator concentrate after decompression drying, for a quick.
in the industrial use of centrifugal extraction mechanism of gynostemma extract phase equilibrium set up fast, easy to implement series single stage or multistage countercurrent flow or wrong washing and extraction, high mass transfer efficiency and grade efficiency approaching 100%, stop not to undermine the established after concentration distribution at different levels, can at any time at all levels of sampling, facilitate testing.
. cwl - use M new centrifugal extraction machine gynostemma in the traditional Chinese medicine extraction, single-stage extraction rate was 95%, the secondary cross-flow extraction rate was 99%, the secondary counter-current extraction rate was 98%, the cross-flow extraction rate is higher than counter-current extraction rate, and single-stage and two-stage extraction rate can reach the requirement of industrial production.
