Centrifugal extraction machine application of traditional Chinese medicine extraction technology to extract rhodiola p. e
when using traditional Chinese medicine extraction technology to extract rhodiola extracts, rhodiola root and rhizome first, crushed into thick powder, using 70% ethanol reflux extraction, divide extract, reduced pressure recovery of ethanol, the concentrate with equal parts water and let stand, filtering, treatment 3 times repeatedly, the filtrate vacuum concentration, in turn, with petroleum ether, chloroform, ethyl acetate, n-butanol extract, ethyl acetate and n-butanol part recovered solvents respectively, raw butyl alcohol and rhodiola glucoside crude products.
in the process of extraction of rhodiola extract, the traditional mode of operation is tank stirring extraction, artificial to separate two phase after stratification by gravitational force, the intermittent operation is more tedious, a longer production cycle. By using. cwl - M new centrifugal extraction machine can not only overcome the above shortcomings, but also can make the extraction period of continuous production, separating the two more completely, less dosage of chloroform, the advantages of higher extraction rate.
