Pogostemon quadrifolius (Benth.) is a medicinal aromatic shrub in family Lamiaceae which is used as folk medicine in India. This present study deals with the preliminary screening of Pogostemon quadrifolius antimicrobial activity and TLC profiling of the crude plant extract. Cold extraction technique was carried out to prepare the crude plant extract, which was further screened for the presence of phytochemicals. The extracts were assessed for antibacterial and antifungal studies by disc diffusion method. Thin layer chromatography was utilized for solvent standardization. Phytochemical analysis revealed the presence of diverse classes of bioactive components. The quantitative analysis of flavanoids, alkaloids and total phenolic content in different extracts varied from each other. Evaluation of antibacterial studies showed that methanolic extract and ethyl acetate extract showed activity against standard and MDR strains respectively. The ethanolic extract also showed fungicidal activity. And finally the solvent standardization was performed for the separation of phytoconstituents by TLC, which showed a very good abundance of active principles (based on their R f values). All these preliminary reports warrant an in depth analysis on the usefulness of Pogostemon quadrifoliusas a miracle drug against various ailments.

Flowers (1000 g) of Ocimum canum harvested at different times (7 am, 10 am, 1 pm, 4 pm, and 7 pm) in a day were separately hydrodistilled and yielded 0.19 -0.27% (w/w) of essential oils. GC and GC-MS analyses revealed that the oils were predominated by oxygenated monoterpenoids (51.2-74.4%). Hydrocarbon monoterpenoids constituted 6.2-10.2% of the oils. Percentage composition of hydrocarbon and oxygenated sesquiterpenoids in the oils were in the range of 1.3-22.0%. The most abundant constituent of the oils was linalool (40.5-58.7%). Other principal constituents were as follows: Limonene (0.6 -7.5%), terpinen-4-ol (1.4-5.6%), eugenol (4.4-8.9%), geranyl acetate (0.2-4.9%), α-trans-bergamotene (3.2-9.4%) and (E)-isoeugenol (4.1-5.5%). The predominance of linalool in the oils showed that the oils were of linalool chemotype. Antibacterial activity of the oils was evaluated against Staphylococcus aureus and Escherichia coli using agar diffusion method. Irrespective of the time of collection of the flower, the oils were found to be active against the tested organisms. However, they are more active on Escherichia coli than Staphylococcus aureus. The activity of the oils on the organisms was concentration-dependent.
