The present study is to evaluate the phytochemical constituents and antimicrobial activity of Plectranthus amboinicus leaf extract using petroleum ether, methanol and water as solvents. The antimicrobial activity of P. amboinicus leaf extracts were examined against the selected bacterial and fungal isolates namely Escherichia coli, Staphylococcus aureus and Aspergillus niger, Candida albicans using agar well diffusion method. FT –IR analysis was performed to identify the presence of functional groups in the methanol extract. The results of the study revealed the presence of distinctive active secondary metabolites in the tested leaf extract. The results revealed that the methanol extract exhibited maximum antimicrobial activity against the tested bacterial and fungal isolates when compared with aqueous and petroleum ether extracts. The FT-IR analysis reveals the presence of functional groups such as hydroxyl, amines, alkynes, ketones and carboxylic acid in the methanolic extract of P. amboinicus. Thus, P. amboinicus leaves are effective against the selected microbes and recommends that the plant derived phytochemicals are comparatively safer than synthetic alternative, thereby contributing insightful remedial benefits for the treatment of diseases.

The available controlling agents for mosquito vectors are chemical insecticides and the frequent usage of these insecticides creating resistance among mosquito vectors and environmental pollutions. Thus, the study was designed to synthesize and characterize the Ag nanoparticles (AgNPs) through a methanol leaf extract of Ocimum canum and find the larvicidal prospective of the AgNPs on the 4th instar larvae of Anopheles stephensi, Culex quinquefasciatus, and Aedes aegypti. The obtained outcomes show that the methanol leaf extract of O. canum was effectively reduced the silver ions and produce constant silver nanoparticles. It was characterized and confirmed by various scientific techniques such as UV-vis spectrum, XRD, SEM, FT-IR and EDaX. Various concentrations (10, 50, 150, 200, and 250 ppm) of characterized nanoparticles were tested for larvicidal activity. The premier larval death was observed at 24 h of treatment on A. aegypti with LC50= 17.03 ppm, followed by C. quinquefasciatus with LC50= 14.89 ppm of methanol extract of O. canum and no death was noticed on A. stephensi. The LD90 value for A. aegypti and C. quinquefasciatus were 24.18 & 20.65 ppm respectively. Hence, the Ag nanoparticles produced from methanol leaf extract of O. canum retains efficiency to control A. aegypti and C. quinquefasciatus. Thus, it might support partially to replace the chemical insecticide which used against these vectors and might contribute to reduce environmental pollution.

The objective of the study was to investigate in-vitro antibacterial and antioxidant activities of methanolic extract of Combretum album Pers. root. In brief antibacterial efficacies of methanol extract and its petroleum ether fraction (MePET), chloroform fraction (MeCH), ethyl acetate fraction (MeEA) and water fraction (MeAQ) were determined by agar well diffusion assay along with Minimum Inhibitory Concentrations (MICs). In-vitro antioxidant efficacies were evaluated by DPPH radical scavenging method. Preliminary phytochemical assay, Fourier Transform Infrared Spectroscopy and Gas Chromatography-Mass Spectroscopy analyses were employed to detect the plausible active ingredients. Methanol extract showed broad spectrum antibacterial activity having highest inhibition zone against Staphylococcus aureus MTCC 2940 (21.67±0.58 mm) and MICs ranged from100 µg/ml to 250 µg/ml. The scavenging activity of methanol extract of root of C. album was concentration dependant and IC50 value was 136.08 µg/ml. The lowest MIC (5 µg/ml) was noted with MeCH against B. subtilis (MTCC 441). MeCH showed highest antioxidant activity with an IC50 value of 12.98 ?g/mL and MePET, MeEA, MeAQ and Ascorbic acid presented antioxidant potential with IC50 values of 16.10, 15.07, 17.44 and 13.40??g/mL respectively. Preliminary phytochemical tests and FT-IR analysis revealed presence of various phytochemicals and functional groups like hydroxyl, carboxylic acids, amidines, amines, aromatics and esters. Three compounds were elucidated from bioactive TLC fraction of MeCH in GC-MS analysis supported by presence of various functional groups in MeCH as detected in FT-IR analysis. It is concluded that methanolic extract of C. album root is a potential antibacterial and antioxidant agent where presence of N-[5-[4-pyridinyl)-1H-1,2,4-triazol-3-yl]-benzamide (compound 1), pyruvic acid (compound 2) and methyloacetone (compound 3) are responsible as possible active ingredients.

Aim: To investigate the antimicrobial efficacy of various solvents leaf extracts of Aegle marmelos, Plumbago zeylanica and Rhinacanthus nasutus against human pathogenic organisms such as Acinetobacter baumannii, Salmonella enteriditis, Bacillus cereus, Streptococcus pneumonia, Mycobacterium tuberculosis and Aspergillus fumigatous by agar well diffusion method. Background: Also, this is the first time report on MIC and MBC/MFC activities and identify the phytochemicals and functional groups using HPLC, GC-MS and FT-IR analysis. Objective: Minimum inhibitory concentration (MIC), minimum bactericidal (MBC/MFC) values were also carried out by the micro dilution method. Methods: Ethyl acetate extract of P. zeylanica showed better antimicrobial activity against the tested pathogens, especially for S. pneumoniae (40 mm) followed by ethyl acetate extract of R. nasutus (36 mm) against S. pneumoniae. While least inhibition was observed for aqueous extract of P.zeylanica against S. enteritis (10 mm). Results: The MIC ranged from 3.75 µg/ml to 60µg/ml and MBC/MFC 7.5 µg/ml to 60 µg/ml. Phytochemical analysis exhibited the presence of alkaloids, steroids, saponins, flavonoids, tannins, terpenes, phenolics and cardiac glycoside in all samples of selected plant extracts. Tannins, phenolics and glycoside were found only in the ethyl acetate extract of P.zeylanica. HPLC and GC-MS analysis of ethyl acetate leaf extract of P. zeylanica exposed ten major peaks and eleven compounds respectively. Chemical nature of the leaf extract was analysed by FT-IR spectrum. Conclusion: Ethyl acetate leaf extract of P. zeylanica showed better antimicrobial activity than other extracts as well as standard drugs. Therefore, this plant could be studied in detail for the identification of active biomolecules for antimicrobial agents.

The alkaloids of Tylophora have been shown to have an anti-asthmatic and anti-inflammatory response. The leaves of the plant are used in Ayurvedic medicine for the treatment of asthma, bronchitis, and arthritis. In the cur-rent study, the phyto-constituents and major secondary metabolites found in Tylophora indica leaves and stem were isolated and extracted using differ-ent solvents and analysed by FT-IR spectroscopy to have a semi qualitative analysis by comparing the structure of tylophorine (major secondary metab-olite found in Tylophora leaves having anti-asthamatic activity) with the ex-tracted product. The chloroformic leaf extract (200μl) of T. indica was inves-tigated for altered immunologic response in mice. In response to plant ex-tract, lymphocyte count increased in mice representing the immuno-stimulatory effect of plant extract.
