Abstract

The antimicrobial activity of methanol and acetone extracts of Butomus umbellatus, Polygonum amphibium, and two species of the genus Sparganium (S. erectum and S. emersum) against three Gram-positive, five Gram-negative bacteria and one fungus was assessed by the disk diffusion method. The microorganisms used were Staphylococcus aureus ATCC-29740, Escherichia coli ATCC-25922, Pseudomonas aeruginosa ATCC-15442, Salmonella typhi NCTC-9394, Klebsiella pneumoniae NCTC-5046, Proteus vulgaris ATCC-7829, Bacillus subtilis ATCC-6633, Corynebacterium diphteriae RSHM-633 and Candida albicans ATCC-10231. Methanol extracts of the plants did not exhibit any inhibitory activity against any of the microorganisms, while the acetone extracts of the all tested plants only showed significant activity against Bacillus subtilis, with inhibition zones and minimal inhibitory concentration values in the 7-16 mm and 0.49-12.50 mg/mL ranges, respectively.

Highlights

Interest in plant-derived drugs has been increasing, mainly due to the current widespread belief that “green medicine” is safer and more dependable than costly synthetic drugs, many of which have adverse side effects [1].The monotypic genus Butomus is the only member of the Butomaceae family, which is allied to Alismataceae and the non-European Limnocharitaceae [2]
Amphibium and B. umbellatus were inactive against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Proteus vulgaris and Corynebacterium diphteriae bacterial species, as well as a fungal species
These differences could be due to their different habitats, as S. erectum grows at the edge of waters as an emergent species while S. emersum grows in water with 0.2-1 m deep as a submersed plant

Summary

Introduction

Interest in plant-derived drugs has been increasing, mainly due to the current widespread belief that “green medicine” is safer and more dependable than costly synthetic drugs, many of which have adverse side effects [1].The monotypic genus Butomus is the only member of the Butomaceae family, which is allied to Alismataceae and the non-European Limnocharitaceae [2]. In this preliminary antimicrobial assay, we wish to report on the antimicrobial activity of the methanol and acetone extracts of the aquatic plants P. amphibium, B. umbellatus, S. emersum, and S. erectum. The inhibitory activities of the extracts of S. erectum and S. emersum, B. umbellatus and P. Acetone extracts of the whole plant of S. erectum, S. emersum, P.
