Aim:The aim of this study was to evaluate the effect of lemon, ginger, garlic, and honey extracts on Streptococcus mutans. Materials and methods:Commercially obtained honey, ginger, garlic, and lemon were included in the study to evaluate its efficacy in isolation and in combination against S. mutans. The efficacies of extracts were tested using well diffusion method, and its effect was evaluated by measuring the zone of inhibition around the well. Antimicrobial activity of the extracts was carried out individually and compared considering triplicates of all the extracts.Results: When individual comparison of the extracts was made, garlic showed greatest antimicrobial activity with a mean zone of inhibition (34.9 ± 0.58 mm) and honey showed least antimicrobial activity (0.5 ± 0.6 mm). When combinations of extracts were tested against S. mutans, lemon and garlic combination showed the greatest zone of inhibition (27.6 ± 0.43 mm) compared with other combinations, and ginger + lemon combinations showed the least zone of inhibition (12.6 ± 0.43 mm).

Objective: The objective of the present study is to determine the possible phytoconstituents identified by gas chromatography and mass spectrometry (GC-MS) analysis of an ethanolic leaves extract of Elettaria cardamomum L. Maton.Methods: The extraction of E. cardamomum was done by cold solvent extraction system at room temperature. GC-MS analysis of lyophilized ethanolic leaves extract of plant samples was carried out by GC-MS-GC Clarus 500 Perkin Elmer. Results: In E. cardamomum, 21 phytochemicals were identified among which retinal, 9-cis-showed the highest area (44.86%) and benzeneethanamine, α-methyl- showed the lowest area (0.12%). The major compounds identified were retinal, 9-cis-, 1-heptatriacotanol, phytol, n-hexadecanoic acid, naphthalene,decahydro-1,1,4atrimethyl-6-methylene-5-(3-methyl-2-4-pentadienyl)-[4aS-(4aα,5α,8aα)]-, β-pinene, 2H-pytan-3-ol,6- ethenyltetrahydro-2,2,6-trimethyl-and cyclopropane, trimethanol, (2-methyl-1-propanylidene).Conclusion: GC-MS analysis revealed the presence of hydrocarbon alkane, ester, terpenes, phenolic compounds, steroids, and fatty acids in E. cardamomum. These active phytoconstituents contribute to the medicinal efficacy of the plant, and the plant can be used for the sourcing of these compounds.
