Methanolic extraction, crude alkaloid fractionation and separation using different chromatographic techniques (open columns and preparative TLC) were used for isolation of pure compounds. The structure of the isolated compounds were elucidated by spectroscopic methods such as UR - http://ecollib.ump.edu.my/3867/ ER -
