Abstract :
This study undertaken to determined the
phytochemical screening and antimicrobial activity of
ethanol and aqueous extract of Pawpaw leaf. A Fresh leaves
of Pawpaw were collected from the Department
Agricultural Technology, Ramat polytechnic Maiduguri,
and allowed to dry under the shed for 10 days. The
powdered plant materials were soaked in a conical flask and
extracted with ethanol and aqueous. Phytochemical
analysis was conducted by using specific standard
procedure, Antimicrobial activity assays of all the extracts
were performed by agar well diffusion methods and
determined by measuring the zones of inhibition with
transparent scale. The result of phytochemical screening
revealed the presence of Tannin, Saponins, Alkaloids,
Flavonoids and Phenol on ethanol extract while the
Aqueous leaf extract shows the presence of Saponins,
Tannin, Flavonoids, Alkaloids but Phenol was absent. The
result of antimicrobial activity showed that E. coli has
higher sensitivity of (10.0mm) zone of inhibition followed by
Staphylococcus aureus (9.2mm) and Bacillus species has the
least sensitivity of (7.5mm) amongst the organism
ascertained with zone of inhibition on the ethanol extract
and in aqueous extract the E. coli has the higher sensitivity
of (8.2mm) zone of inhibition while Staphylococcus aureus
and Bacillus species has not detected zone of sensitivity
amongst the organism ascertained. The study revealed some
of acclaimed medicinal importance of Pawpaw (Carica
papaya) leaves and can be made available commercially for
its medicinal value.
