Background: The only remedy for up surging problem of antibiotic resistance is the discovery of antibacterial agents of natural origin. Objective: The present study was aimed at finding antibacterial potential of crude and solvent extracts of mature leaves of Plumeria pudica. Methods: Antibacterial activity of three different solvent extracts were evaluated in four human and four fish pathogenic bacteria by measuring the zone of inhibition and determining Minimum Inhibitory Concentration and Minimum Bactericidal Concentration values. Standard antibiotics were used as positive control. Preliminary phytochemical screening of most effective extract i.e., ethyl acetate extract, Fourier Transform Infra Red analysis and GC-MS analysis of the Thin Layer Chromatographic (TLC) fraction of ethyl acetate extract were done meticulously. All experiments were done thrice and analyzed statistically. Results: Crude leaf extracts and solvent extracts caused good inhibition of bacterial growth in all selected bacteria. Ethyl acetate extract showed highest inhibition zones in all tested strains with maximum inhibition (19.50±0.29 mm) in Escherichia coli (MTCC 739). MBC/MIC of the extracts indicated that all three solvent extracts were bactericidal. Preliminary phytochemical tests revealed the presence of tannins, steroids and alkaloids and FT-IR analysis revealed presence of many functional groups namely alcoholic, amide, amine salt and aldehyde groups. From the GC-MS analysis of TLC fraction of ethyl acetate extract five different bioactive compounds e.g., 2,4-ditert –butylphenyl 5-hydroxypentanoate, Oxalic acid; allyl nonyl ester, 7,9-Ditert-butyl-1-oxaspiro(4,5)deca-6,9-diene-2,8-dione, Dibutyl phthalate and 2,3,5,8-tetramethyl-decane were identified. Conclusion: Leaf extracts of P. pudica contain bioactive compounds that can be used as broad spectrum bactericidal agent.

Delonix elata L., belongs to family Fabaceae used by the traditional various medicinal practices to cure jaundice, skin disease, heart disease, cancer cell formation, physiological abnormalities, heptoprotective, bronchial and rheumatic problems. The present study was screen the antimicrobial and phytochemical activity of alkaloid leaf extracts. This extracts was assessed on multidrug resistant clinical isolated from both gram positive, gram negative and antifungal strains including Bacillus subtilis, Staphylococcus aureus, Escherchia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. The zone of inhibition was determined by Agar well diffusion method with various concentration. GC- MS analysis was performed to identify major bioactive compounds present in the extracts. The GC – MS studies shown the present of 25 compound were identified in the leaf extract composition. The antimicrobial analysis revealed that C. albicans showed a highest zone of inhibition 25mm at 100 mg/ml of extracts. Present finding suggest that D. elata as plant pharmaceutical and pharmacological importance.

Objective: In the present study is investigated of phytochemicals and antioxidant activities of the leaf extracts from Meliosma simplicifolia (L.). Methods: The seaweed sample was subjected to extraction with solvents of different polarities (hot water, methanol, acetone, chloroform, and petroleum ether) and screened for phytochemicals according to standard methods. The ability of the plant extract to act as hydrogen/electrons donor or scavenger of radicals was determined by in vitro antioxidant assays using 2,2-diphenyl-2-picryl-hydrazyl free radical (DPPH) scavenging, reducing power assay, and superoxide radical (O2•) scavenging activity. The ICPMS and GC-MS analysis of the methanol leaf extract of M. simplicifolia was revealed the presence of antibacterial. Results: Phytochemical analysis revealed the presence of Preliminary metabolites Quantitative studies of estimated phenol, flavonoid and tannin, as for the methanol extract of stem showed the highest content of phenolic compounds (40.71±0.94 GAE mg/100). Antioxidant activities were concluded the estimation M. simplicifolia leaf for as followed the studies. In leaf the highest DPPH scavenging activity (132.3 μg/ml), ICP-MS analysis of the leaf extract showed the presence minerals such as Mg, Fe, Cu, Na, and Zn in excess. The leaf extract of the plant was also tested for its antibacterial activity and results confirmed that it has potential activity. Conclusion: The preliminary studies in the methanol extract of the leaf of M. simplicifolia are suggestive of the antibacterial potentials of the methanol extract of leaves of M. simplicifolia.

Objective: The present study was performed to identify the phytochemical constituents of leaves and flowers of a plant Spermadictyon suaveolens extracted with four different solvents.Methods: Dried and powdered samples were subjected to soxhlation based on the polarity of the solvents. The extracts were scanned using Ultra Violet-visible (UV-Vis) spectrophotometry with the wavelength ranging from 200–800 nm by comparing the absorption spectrum with the spectra of known compounds, Fourier Transform Infrared (FT-IR) spectrometry was used to find out the functional groups of the compounds and GC-MS system consisting of a Perkin Elmer Technologies Model Clarus 680 GC equipped with Clarus 600 (EI) was used to identify the metabolites by matching their recorded mass spectra with the standard mass spectra from National Institute of Standards and Technology (NIST05. LIB) libraries provided by the software of the GCMS system (TurboMass version 5.4.2).Results: The phytochemical tests indicated the presence of carbohydrates, alkaloids, flavonoids, phenols, tannins, saponins and terpenoids from the chloroform extract of leaves and flowers. UV-visible spectrophotometer results indicated a wavelength range between 230–660 nm for the flower and leaf extracts for major peaks. FT-IR analysis indicated major functional groups such as aromatic, primary, secondary and aliphatic amines, alkanes, carboxylic acids and amides. GC-MS analysis results revealed major bioactive compounds in the crude extracts.Conclusion: Presence of secondary metabolites has been identified from the phytochemical studies. Many phyto-compounds have been identified from the leaves and flowers of using GC-MS analysis. Hence, this medicinal plant may be used as a source for treating many diseases.

Phyllanthus wightianusbelongs to Euphorbiaceae family having ethnobotanical importance. The present study deals with validating the antimicrobial potential of solvent leaf extracts ofP. wightianus. 11 human bacterial pathogens (Bacillus subtilis,Streptococcus pneumoniae,Staphylococcus epidermidis,Proteus vulgaris,Pseudomonas aeruginosa,Klebsiella pneumoniae,Salmonella typhimurium, Escherichia coli, Shigella flexneri, Proteus vulgaris, andSerratia marcescens) and 4 fungal pathogens (Candida albicans, Cryptococcus neoformans, Mucor racemosus, andAspergillus niger) were also challenged with solvent leaf extracts usingagar well and disc diffusion methods. Further, identification of the active component present in the bioactive extract was done using GC-MS analysis. Results show that all extracts exhibited broad spectrum (6–29 mm) of antibacterial activity on most of the tested organisms. The results highlight the fact that the well in agar method was more effective than disc diffusion method. Significant antimicrobial activity was detected in methanol extract againstS. pneumoniae(29 mm) with MIC and MBC values of 15.62 μg/mL. GC-MS analysis revealed that 29 bioactive constituents were present in methanolic extract ofP. wightianus,of which 9,12-octadecaenioic acid (peak area 22.82%; RT-23.97) and N-hexadecanoic acid (peak area 21.55% RT-21.796) are the major compounds. The findings of this study show thatP. wightianusextracts may be used as an anti-infective agent in folklore medicine.
