PHYTOCHEMICAL ANALYSIS AND ANTIBACTERIAL ACTIVITY OF MUSA PARADISIACA (PLANTAIN) FLOWER
Abstract
The study reported the phytochemical composition and antimicrobial effects of
Musa paradisiaca flower. Matured Musa paradisiaca flowers powder was
extracted by cold extraction and analyzed qualitatively for phytochemicals using
ethanol and water as solvents. The antimicrobial activities of the extracts were
determined in-vitro against Escherichia coli, Pseudomonas aeruginosa, Klebsiella
pneumonia and Actinomyces spp by agar well diffusion method. Results of the
phytochemical screening showed the presence of alkaloids, saponins, tannins,
flavonoids, glycosides and reducing sugars. The extracts showed activity against
the test organisms at 200, 100 and 50mg/mL. Zones of inhibition range from 7.0
to 20.0mm. Pseudomonas aeruginosa (20mm), Klebsiella spps (17mm),
Actinomyces spp.(15mm) and Escherichia coli (10mm). Only Klebsiella spps
showed MIC at 200mg/ml of the ethanol extract. No MBC was observed. The
agueous extract was more potent than the ethanolic extract of Musa paradisiaca
flower. This implies that extract of Musa paradisiaca flower exhibit antimicrobial
activity at high concentrations. This finding, presents useful information about the
use of Musa paradisiaca flower for medicinal purposes, specifically as a poultice
in the treatment and management of wounds as claimed in the folklore medicine
