  Objective: Continued resistance toward the antibiotics urges us to explore newer antibiotics. Plants are being the safer source of antibiotics with lesser or no side effects. This study was designed to study the presence of phytochemical constituents and antibacterial activity of leaf and flower extracts of Wedelia glauca against urinary tract infection causing pathogens.Methods: The plant leaves were extracted with five different solvents based on the polarity. The extraction was done using soxhalation. Antimicrobial activity was determined by agar well diffusion method for both the sample and standard. The acetone plant extract was subjected to gas chromatography-mass spectrometry (GC-MS) analysis for screening phytoconstituents.Results: Preliminary phytochemical screening revealed the presence of diverse phytoconstituents in the plant. The different extracts exhibited a considerable antimicrobial potential. Among the solvents used acetone extract showed comparably better antimicrobial activity with 100% of inhibition rate with the maximum zone of inhibition of 1.6±0.77 mm against Staphylococcus sp. and Aspergillus sp. at the concentration of 5 mg. GC-MS analysis provided 8 major peaks which revealed the existence of a variety of bioactive compounds which may attribute to the efficacy of the plant.Conclusion: W. glauca leaf and flower extracts displayed a broad spectrum of antibacterial and antifungal activity and can be considered as a potential source of newer antibiotic compounds.

Objective: The essential oil and scented extracts of Michelia alba DC. were analyzed by gas chromatography–mass spectrometry (GC–MS) and investigated for antidiabetic activities in vitro and in silico.Methods: The identification of steam distilled essential oil and scented extracts of M. alba was performed by GC–MS on the Agilent 7890A chromatograph couple with GC-7000 Mass Triple Quadrupole. The extractions have been evaluated the antidiabetic activities by alpha-amylase (α-amylase) assay using starch as substrates. In addition, computational molecular docking analysis of significant components was studied to understanding how selected compounds interacted with α-amylase using AutoDock 4.2.Results: The yields of M. alba of steam distilled essential oil and solvent extractions including hexane, diethyl ether, and dichloromethane were 0.16%, 0.02%, 0.47%, and 0.92%, respectively. GC–MS analysis of essential oil revealed that the main component was monoterpenoids β-linalool (65.03%). Meanwhile, 2-methylbutanoic acid was a primary in hexane extract (36.54%) and dichloromethane extract (33.07%). In the case of ether extract, the primary compound was β-linalool (37.32%) same as in essential oil. The antidiabetic activities evaluation demonstrates that essential oil and scented extracts have shown promising α-amylase inhibition activity. Essential oil from steam distillation revealed the best inhibition potential with a half maximal inhibitory concentration value of 0.67±4.7 mg/ml and their significant components demonstrated negative binding energies, indicating a high affinity to the α-amylase-binding site using molecular docking simulation.Conclusion: Data from this study suggest that essential oil and scented extracts of M. alba DC possess in vitro α-amylase activities and can be used for therapy of diabetes.

Sargassum polycystum is a brown seaweed, which has been reported to contain various phytoconstituents especially antimicrobial properties. However, the study on phytochemical components and biological activities of S. polycystum are yet fully understood. Therefore, the objectives of this study are to evaluate the best extraction solvents for S. polycystum and to determine the percentage of phytocomponents obtained in the n-hexane, dichloromethane (DCM) and methanol extracts of S. polycystum via Gas Chromatography-Mass Spectrometry (GC-MS) analysis. S. polycystum was collected from the coastal area of Sabah, Malaysia. After collection, it was rinsed, dried and extracted with n-hexane, DCM and methanol by soxhlet extraction. The fatty acid compounds (FAME) analysis was done using The Perkin Elmer Turbo Mass Spectrometer.  This study showed that methanol is the most efficient solvent as it produced the highest extraction yield with 3.83%, followed by n-hexane with 1.69% and lastly DCM with 0.59% in S. polycystum. On top of that, this study has found 19 phytocomponents in all extraction methods of S. polycystum, which have been proven to possess antibacterial constituents such as palmitic acid, myristic acid, oleic acid, pentadecanoic acid and behenic acid as assessed by GC-MS analysis.

The botanic genera Pistacia are groups around een species of shrubs that belong to the Anacardiaceae family which is believed to have originated in Asian or Mediterranean region. P. len scus is abundant species of the Pistacia genus encountered in the forest region of Ouarsenis mount (Northwest of Algeria), exactly in the na onal park of Thniet El Had in the Wilaya of Tissemsilt in Algeria. In the present study, chemical composi on and an bac- terial ac vi es of essential oil (EO) of P. lentiscus were evaluated. The EO was isolated and analyzed by gas chromatography-mass spectrometry (GC- MS). The minimum inhibitory concentra on (MIC) was determined using 6 strains of Gram-positive and negative bacteria. The antibiogram was made following the gliosis-environment diffusion method and which makes it possible to determinate bacteria’s sensibility to an bio cs. From a exponential culture (18 to 24 hours), a bacterial suspension was prepared and well- homogenized a erwards. The opacity was adjusted equivalent to 0.5 McF (McFarland). Based on the GC-MS analysis, thirty five compounds representing 100 % of the total oil composi on were iden ed. The essen al oils could be explored to test their an microbial activity, especially against some bacteria that cause alimentary intoxications. The results revealed that the essen al oil exhibited strong levels of an bacterial activity against the tested microorganism regarding the MIC values, Salmonella sp was found to be the most sensitive strain (inhibition zone 23cm MIC 1.25%). Based on the  findings of the present study, new an bacterial agents could be developed, and the use of P. lentiscus should be promoted in the traditional treatment of ailments.
