Abstract

The aim is to study the phytochemical constituents present in Croton bonplandianum leaf and stem. Preliminary phytochemical analysis revealed the presences of phytochemicals such as carbohydrates, quinines and glycosides in all the tested extracts in both the leaf and stem of Croton bonplandianum. Coumarins, proteins, steroids, phytosteroids, phlobatannins and anthraquinones were absent in all the tested extracts. The amount of total phenolics, total flavonoids and tannin content in hexane, ethyl acetate and methanol extracts of leaf and stem were determined spectrometrically. The hexane, ethyl acetate and methanol extract of stem showed higher total phenolic, flavonoid and tannin content then leaf. The present study suggested that, detailed studies on the isolation and characterization of the leaf and stem extracts as well as investigations on other biological studies and in vivo assays will be interesting in discovering new drugs.
