II. Precipitation of alkaloids with alkaloids precipitating reagents
Examples of the alkaloidal pptating agent e.g. Mayer’s, wagner’s, dragendorff’s

The insoluble alk-complex with these reagents are purified by :
Filtration. .1

Decomposition of the insoluble alk-complex to get the free alkaloid .2
(regeneration).

Extraction of the free alk. base with suitable organic solvent. .3

2) Partition Process:
