Abstract

Chloroform and water extractions of Aloe vera and Neem Azadirachta indica leaves were carried out so as to quantify the phytochemical yields in such samples, and to identify their main constituents of active compounds.. The percentage yields obtained through the soxhlet (chloroform) extraction for the A. vera and neem plants were 8.6% and 14.3%, while the percentage yields for the aqueous extracts of the two plants were 5.4% and 6.2%, respectively. The result of the phytochemical screening showed the presence of tannins, flavonoids, terpenoids, carbohydrates, and alkaloids for the A. vera plant with saponins, glycosides phlobatannins, antiquinones carbohydrates, and steroids been absent, while the neem plant contains flavonoids, steroids, carbohydrates, glycosides, antiquinone, terpenoides and alkaloids, with saponins, tannins, phlobatannins been absent. The occurrence of these biologically active chemicals in Neem and A. vera plants may justify their wide usage in traditional medicine.

Keywords: Phytochemials , neem,  Aloe vera, extraction yields, bioactive compounds.
