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.
