Chemical composition: stem contains anthraquinones, mainly for the emodin, rhubarb, phenol or emodin methyl ether, both exist in combination model. Stem leaves contain many kinds of flavonoids, has been mignonette element - 5 - O- Xylose glycoside. Also contains anthraquinone compounds, have share emodin, emodin methyl ether, emodin - 8 - O-5 - O- Xylose glycoside. Also contains anthraquinone compounds, have share emodin, emodin methyl ether, emodin - 8 - O- β- D - Dextrose glucoside; And beta Sitosterol. Pilot test is tannins and stilbene type.
in the tuber fleeceflower stem after crushing, alkalization, extraction, tuber fleeceflower stem base mainly dissolved in the water extraction liquid; After adjust pH, tuber fleeceflower stem alkali free out from the water, then using chloroform extraction, the tuber fleeceflower stem base into chloroform, then continue to complete follow-up purification crystallization operation.
in chloroform extraction process, 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.
