Resin Adsorption Technology in Extraction of Alkaloids
What are Alkaloids?
Alkaloids, also known as organic bases, are widely distributed in many plant materials, and most of them have significant physiological activities. There are many kinds of alkaloids, and the structure is very complex. It has a lipophilic alkaloid and a hydrophilic alkaloid, but its commonality is alkaline and can be salty with acid. Its alkalinity can be characterized by the value of its conjugated acid pKa, and the pKa value of alkaloids is characterized. The pKa value of alkaloids can be changed from 0 to 13, indicating that their alkalinity is very different.
