In this study we have attempted to explore sufficient scientific grounds for promising memory enhancing properties of ricinine by studying its anti-AChE and antioxidant potentials.
For inhibition study, ricinine (10-132 ug/ml) was mixed with standard solution of substrate and the mixture (sample+standard) was injected into a stream of the phosphate buffer passed through the immobilized enzyme column and decrease in absorbance (Ai) was recorded.
For percent scavenging activity ricinine solution at final concentration of 10-160ug/ml was mixed with 1 ml ABTS and incubated at room temperature for 10 min.

The castor plant contains in its seeds a group of closely related toxicglycoproteins (the ricin group), ricinoleic acid (12-hydroxyoleic acid) and the alkaloid
ricinine. Ricin is capable of interfering with digestion, absorption and retention of nutrients ((Onimisi et al., 2008).
Further investigations are needed to evaluate the nematicidal potential of substances found in the castor leaves, such as the alkaloid
ricinine (MOSHKIN, 1986).
