Selective Recovery of Alkaloids from Glaucium Flavum Crantz Using Integrated Process Extraction-Pertraction

Abstract

Selective recovery of aporphine alkaloids from Glaucium flavum Crantz was studied. The alkaloids were successfully recovered from aqueous solutions, including native extracts of Glaucium flavum Crantz, applying pertraction in a rotating discs contactor. As a liquid membrane n-heptane and as receiving solution diluted phosphoric acid were used. Pertraction was also coupled to solid-liquid extraction in order to simultaneously purify the extract obtained from the plant. This integrated extraction-pertraction process was very simple, rapid, and efficient. The permeation of alkaloids through the liquid membrane was very selective and their purity in the receiving solution was 88.7%.
