Swietenia Mahagoni

The present study was designed to evaluate the phytochemical analysis and antibacterial activity of Swietenia mahagoni leaf extract. The leaf extract was subjected to a variety of phytochemical analysis. The qualitative phytochemical tests exhibited the presence of common phytocompounds like alkaloids, tannins, saponins, phlobatannins, flavanoids, terpenoids and volatile oils as major active constituents. The plant (Swietenia mahagoni) leaf has valuable medicinal uses, hence petroleum ether (18.2g) was found to be a good solvent for the phytochemical and antibacterial study. Similarly, the Methanolic leaf extract of Swietenia mahagoni has highest zone of inhibition on Bacillus subtilis.

Background: Carvacrol is an aromatic phenolic terpenoid widely existing in the volatile oils of thyme, oregano, and some other aromatic plants. Recent studies have found that carvacrol possesses excellent antibacterial activity. In order to provide an updated information about the antibacterial potentials of carvacrol, herein, we summarized recent publications about the antibacterial activity of carvacrol, with special attention paid to its antibacterial molecular mechanisms, including desrupting cell membrane, depleting intracellular ATP, inducing reactive oxygen species, inhibiting efflux pumps, as well as suppressing two important virulence factors, biofilm and quorum sensing. In conclusion, carvacrol is a promising natural antibacterial compound with potential application in food preservation and infection.Keywords：Carvacrol, antibacterial mechanisms, biofilm, quorum sensing

Phytochemical Investigation

The phytochemical investigation of eight Jungermaniales liverwort species: Bazzania decrescens, B. madagassa (Lepidoziaceae), Plagiochila barteri, P. terebrans (Plagiochilaceae), Isotachis aubertii (Isotachidaceae), Mastigophora diclados (Lepicoleaceae), Radula appressa (Radulaceae), and Thysananthus spathulistipus (Lejeuneaceae), collected from Madagascar, has been carried out to afford new and structurally interesting terpenoids and aromatic compounds. The biological activities of the isolated secondary metabolites were determined and the herbertene-type sesquiterpenoids were shown to have antibacterial activity. A new ent-clerodane diterpene from Thysananthus spathulistipus and bis-bibenzyls-type aromatic compounds exhibited strong inhibition of NO production in RAW 264.7 cells, while marchantin C produced moderate α-glucosidase inhibition. The chemosystematics of the studied species are discussed.

Objective: The main objective of the present work is to carry out the phytochemical constituent present and physicochemical analysis of microwave-assisted extract (MAE) of Coriandrum sativum leaves and to investigate its antibacterial activity. Methods: The powdered samples of the leaves were extracted and analyzed for physicochemical properties. Extraction was carried out for C. sativum using different solvents and used for phytochemical investigation. Infrared (IR) spectrum and antibacterial activity of MAE were carried out. Results: The results show that the percentage extract is different in the different solvents and also differs in phytochemical constituents. Phytochemicals present in the MAE also confirmed by IR spectroscopy. MAE is active against bacteria. Conclusion: The phytochemicals present in C. sativum is confirmed by IR spectrum and these phytochemicals responsible for antibacterial activity.

Objective: The objective of this study was to evaluate the antimicrobial activity of volatile oils from aromatic plants against pathogenic bacteria.Methods: Thai aromatic plants such as Pogostemon cablin (Blanco) Benth (Patchouli oil), Cymbopogon nardus Rendle (Citronella grass oil), Pelargoniumroseum (Geranium oil), Syzygium aromaticum (L.) Merrill and Perry (clove oil), Cinnamomum spp.(cinnamon oil), and Cymbopogon citratus (DC.) Stapf.(lemongrass oil) were selected. Essential oils were obtained by water distillation and were stored at 4°C until use. Five human pathogenic bacteria wereobtained from Thai traditional Medicine College, Rajamangala University of Technology, Staphylococcus epidermidis, Escherichia coli, Staphylococcusaureus, methicillin-resistant S. aureus (MRSA), and Pseudomonas aeruginosa. The antibacterial activity of volatile oils was determined by disc-diffusionassay. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of each essential oil were determined.Results: Our study showed that 10% of essential oil from Cinnamomum spp. was the most potential against S. aureus, MRSA, and E. coli when assayedby disc-diffusion method with inhibition zones ranging from 37.66±0.57 to 45.33±1.15 mm and from 29.33±0.57 to 36.00±1.00 for lemongrass oilwith MIC and MBC of 1.25%.Conclusion: From this study, it can be concluded that some essential oils have potential antibacterial activity. The present investigation providessupport to the antibacterial properties of essential oils and will be applied to health-care product as aroma antibacterial products.

Abstract Background: At present, the research concerning in vitro experiments of garlic oil and onion oil is limited. The objective of this study was to carry out the research on the effective components of garlic and onion, and to study the antibacterial activity of the two essential oils and their protective effects on cardiomyocytes with hypoxia/reoxygenation (H/R) injury.Method: The protective effect of volatile oils at different concentrations (200, 100, 50, 25, 12.5, 6.3, 3.1mg/L) on the endothelial cell of microvascular in cardiac muscle against H/R injury was examined by MTT and flow cytometer method. The survival rate and apoptosis situation were record. Inhibition zone test was used to evaluate antibacterial activity of volatile oils. MIC and MBC were calculated as well.Results: To achieve a higher survival rate, the optimum concentrations of garlic oil and onion oil were 12.5mg/L and 6.13mg/L and high concentrations of garlic and onion oil decreased the survival rate. Both the 12.5mg/L onion and garlic oil reduced the apoptosis situation of cardiomyocytes. Both garlic oil and onion oil had antibacterial effect on gram-positive bacteria and gram-negative bacteria, and had the best antibacterial effect on cocci of gram-positive bacteria.Conclusion: Garlic and onion oil do have antibacterial activity and protective effects on cardiomyocytes with H/R injury in a concentration range.
