Traditional Chinese medicine extraction technology joint. cwl type centrifugal extraction machine extracting herba leonuri
1. Chemical composition of herba leonuri Herba leonuri: all contain motherwort alkali grass, water Sue alkali, former Spanish summer grass ketone, Spanish summer grass ketone, skunk petals diterpene, motherwort before diterpene and herba leonuri diterpene
2. Fine leaf motherwort: all contain motherwort alkali grass, 4 - Guanidine - 1 - Butanol, 4 - Guanidine - Butyric acid, arginine, motherwort alkali nitrite. Also contains fine grass terpene Ye Yi literacy, different fine leaf motherwort terpene ( And fine leaf motherwort terpene lactones. Leaf aqueous alkali su.
Chinese medicine extraction technology joint. cwl type centrifugal extraction machine
the current motherwort extract motherwort extract process roughly the following
in herba leonuri after crushing, alkalization, extraction, alkali mainly dissolved in the water extraction liquid of motherwort; After adjust pH, motherwort alkali free out from the water, then using chloroform extraction, at this time in herba leonuri alkali into the 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.
