Antimicrobial efficacy of extracts obtained from aerial part, leaves, and flowers of on different periodontal pathogens: An study.

INTRODUCTION

is a medicinal plant widely used in the Indian traditional system of medicine for curing various ailments. However, there has been no report of any study testing its antimicrobial action against dental or periodontal pathogens. Hence, the aim of this study was to evaluate the antimicrobial activity of extract of whole plant, leaves, and flowers of . against four periodontal pathogens, namely,

MATERIALS AND METHODS

Extracts of the aerial part (whole plant), leaves, and flowers of were prepared using cold maceration and ethanol extraction. The extracts were tested for their antimicrobial activity against periodontal pathogens by using serial dilution method at concentration of 12.5, 25, 50, and 100 μg/ml. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of all three groups were determined against all four periodontal pathogenic using thioglycollate broth and chlorhexidine as a positive control.

RESULTS

. and were most susceptible to leaves extract (12.5 μg/ml and 25 μg/ml) followed by whole aerial plant extract (25 μg/ml and 50 μg/ml), but were least susceptible to flower extract (100 μg/ml). Another pathogen, . was most susceptible to whole plant and flower extracts (25 μg/ml), followed by leaves extract (100 μg/ml). Finally, . was most susceptible to flower extract (25 μg/ml), followed by equal susceptibility at 50 μg/ml concentration of either whole plant or leaves extracts.

CONCLUSION

The . ethanol extracts of aerial parts, leaves, and flowers showed good antimicrobial activity against periodontal pathogens.
