ANTIMICROBIAL ACTIVITY OF CLOVE AND CINNAMON MEDIATED SILVER NANOPARTICLES AGAINST Lactobacillus SPECIES - AN in vitro STUDY | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 Background: Clove and cinnamon have antibacterial, antifungal, insecticidal, and antioxidant properties, and have been used in food for centuries as a savouring agent and antimicrobial content. Lactobacilli are responsible for balancing the microflora and being the primary cause of dental caries. In contrast to prescription medications with side effects, herbal products have not been commonly used in formulations.

The aim of this study was to establish and evaluate the antimicrobial activity of silver nanoparticles mediated by clove-cinnamon against Lactobacilli.

Materials and Methods: To make nanoparticles, the clove-cinnamon powder was boiled, filtered, and mixed with silver nitrate solution, then centrifuged at 8000 rpm to form pellets. The solutions were applied to the wells of the inoculated agar plate at varying concentrations and incubated. The agar diffusion method was used to calculate the zones of inhibition for each concentration using a scale.

The antimicrobial activity of silver nanoparticles containing clove and cinnamon extracts against Lactobacilli was strongest at the highest concentrations (15 mm). It was discovered to contain more than Amoxicillin (8 mm).

Conclusion: The analysis found that silver nanoparticles mediated by clove and cinnamon extract had strong antimicrobial activity. In order to develop new formulations, further research and clinical trials would be needed in the future.

ANTIOXIDANT AND ANTIMICROBIAL ACTIVITY OF LYCOPENE EXTRACT AGAINST ORAL PATHOGENS | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 Aim: The aim of the study was to assess the antioxidant and antimicrobial activity of lycopene extract against oral pathogens.

Materials and Methods: Lycopene extract was prepared and the antimicrobial activity was tested against Candida albicans, Streptococcus mutans (gram +), and Lactobacillus sp. 2,2-diphenylpicrylhydrazyl ( DPPH )radical scavenging assay was used to test antioxidant activity. 2 ml of lycopene extract in the concentration range of 10-50 μl was prepared, Absorbance value was measured spectrophotometrically at 517 nm.  To measure the antioxidant activity the DPPH radical scavenging assay was used. 2 ml of lycopene extract in the concentration range of 10-50 μl was prepared in 50% methanol solution and was added to equal volume of 0.1 mM of DPPH solution. The reaction mixture was incubated for 30 min in dark at room temperature. Absorbance value was measured spectrophotometrically at 517 nm.

Results: From present study we can infer that for antimicrobial activity the zone of inhibition of  lycopene at a concentration of 50 µl was 8 for S. mutans, Lactobacillus and Candida,  at concentration of 100 µl was 9,10 and 8 for S. mutans, Lactobacillus and Candida respectively, at concentration of 150 µl was 13,14 and 9 for S. mutans, Lactobacillus and Candida respectively. The zone inhibition of lycopene was maximum for lactobacillus at concentration of 150 µl.

Conclusion: Lycopene with increase in concentration has increased antioxidant activity but was comparatively less when compared to the standard ascorbic acid. Even Though lycopene didn’t have much antioxidant and antimicrobial activity compared to the standard ascorbic acid and amoxicillin antibiotic, it can be used as a natural antioxidant and antimicrobial drug in periodontics for the treatment of periodontal diseases without any side-effects like the chemical drugs which are used commonly.
