Extracts from Ricinus communis
L. (Castor) plant have been used from time memorial in traditional medicine for treatment of many ailments. However the bioactive phytochemicals that confer these biological effects are often not ascertained. Using established protocols we isolated, quantified and determined some biological properties of alkaloids and cardiac glycosides present in the various Castor plant parts (leaves, stems, roots, seeds and capsules). Alkaloids and cardiac glycosides were found to be concentrated highest in the leaves and stems extracts at 11.2 % and 63.60 % yields respectively. The alkaloids and cardiac glycosides extracts gave an appreciable antioxidant and antihemolytic activities when compared with ascorbic acid and butylated hydroxyl anisole which are two known antioxidant and antihemolytic compounds, respectively. The highest antioxidant and antihemolytic activities were expressed by leaves alkaloids and capsules cardiac glycosides at 57.61 % and 379.66 %, respectively. Furthermore extracts of these two phytochemicals also decreases the growth and proliferation of pathogenic Klebsiella pneumonia
and Staphylococcus aureus
. Thus Ricinus communis
L. (Castor) plant phytochemicals are good source of alternative bioactive compounds which may be used in lieu of synthetic drugs that often comes with numerous side effects when administered.
