Herba leonuri for labiatae plants fresh or dry the ground part of herba leonuri. For labiatae, plants of the genus leonurus, summer flowering. The dry above ground for commonly used Chinese traditional medicine, motherwort herb medicine, for the benefit effective components � � � grass, alkali, water containing herba leonuri herba leonuri Sue alkali, motherwort, motherwort and so on the many kinds of alkaloids and benzoic acid, potassium chloride, etc. This paper mainly introduces 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.

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.
