Application of traditional Chinese medicine extraction technology to extract ranunculaceae plants extracts from radix paeoniae alba
At this stage with the development of Chinese medicine extraction technology, the use of traditional Chinese medicine extraction technology to extract the root of herbaceous peony extract has been widely used in the extraction process, root of herbaceous peony extract is extracted from peony ranunculaceae plants, its method has a lot of kinds, it is the peony after refining, concentration, drying, and natural extracts.
Because of its main ingredients of paeoniflorin.
Soluble in methanol, soluble in � � � alcohol.
Under the stable under acidic, alkaline instability.
Good thermal stability.
So can make use of traditional Chinese medicine extraction equipment using ethanol as extracting agent for Chinese medicine extraction.
Chinese medicine extraction equipment to extract the root of herbaceous peony extract process after crushing, acidification, extraction in radix paeoniae alba, radix paeoniae alba mainly dissolved in the water extraction liquid alkali;
After adjust pH, radix paeoniae alba alkali free out from the water, then with ethanol extraction, the root of herbaceous peony alkali into ethanol, and then continue to complete follow-up purification crystallization operation.
in the ethanol 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.
Through the use of new traditional Chinese medicine extraction equipment 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 ethanol, extraction rate is higher, etc.
