In this research, the leaves of Lepechinia heteromorpha (Briq.) Epling, Lepechinia radula (Benth.) Epling and Lepechinia paniculata (Kunth) Epling have been collected in order to perform a phytochemical study. The first species was distilled to obtain a novel essential oil (EO), while the others were submitted to ethyl acetate extraction and secondary metabolite isolation. The chemical composition of the EO from L. heteromorpha has been investigated by Gas Chromatography-Mass Spectrometry (GC-MS) and Gas Chromatography with Retention Indices (GC(RI)), identifying 25 constituents. A major compound, (−)-ledol (21.2%), and a minor compound, (−)-caryophyllene oxide (1.0%), were isolated from the EO and their structures confirmed by Nuclear Magnetic Resonance (NMR) spectroscopy. Other major constituents of the EO were viridiflorene (27.3%), (E,E)-α-farnesene (1.4%), spirolepechinene and (E)-β-caryophyllene (7.1% each), allo-aromadendrene (6.1%), camphor (1.7%), limonene (1.3%) and β-phellandrene (4.6%). The enantiomeric composition of the EO monoterpene fraction was also studied, determining the enantiomeric excess and distribution of α-pinene, limonene, β-phellandrene and camphor. The ethyl acetate extract of L. radula and L. paniculata were fractionated by column chromatography. Spathulenol, angustanoic acid E and 5-hydroxy-4′,7-dimethoxy flavone were isolated from L. radula extract; ledol, guaiol and (−)-carnosol were found in L. paniculata.

  Objective: This study was aimed to assess the phytoconstituents, cytotoxic, and antioxidant efficacy of ethyl extract of Cleome gynandra leaves.Methods: Qualitative phytochemical analysis with different solvent extracts was performed. Quantitative and gas chromatography-mass spectrometry (GC-MS) analysis of the extract was performed with ethyl acetate extract. The cytotoxic effect of the ethyl acetate extract was determined by 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyltetrazolium bromide (MTT) assay on Michigan Cancer Foundation-7 (MCF-7) cells using taxol as standard and free radical scavenging ability using 1,1-diphenyl-2-picrylhydrazyl (DPPH).Results: Leaves extracts with different solvents revealed the presence of alkaloids, cardiac glycosides, flavonoids, phenols, and tannins. GC-MS analysis of ethyl acetate of the plant leaves showed the presence of n-hexadecanoic acid. The IC50 value of the ethyl acetate extract was found to be 90.2 μg/ml on MCF-7 cell line, and the extract was found to possess significant DPPH free radical scavenging activity.Conclusion: From the results, we conclude that the C. gynandra extract possesses antioxidant and antiproliferating activity against MCF-7 cells.

Objective: The aim of this study was to evaluate the antibacterial and antioxidant properties of ethyl acetate extract of Streptomyces omiyaensis SCH2. The chemical constituents of the extract were investigated using gas chromatography-mass spectrometry (GC-MS).Methods: Secondary metabolites from S. omiyaensis were produced by submerge fermentation using ISP2 medium with 3% NaCl (w/v) for 21 days. The culture filtrate was extracted with ethyl acetate. The chemical constituents were detected in the GC-MS analysis. Antibacterial activity was performed using disc diffusion and broth microdilution methods. Antioxidant activity was evaluated by determining the reducing power capacity and free radical scavenging assays.Results: The GC-MS analysis of the SCH2 extract revealed the presence of four compounds. The main constituents were 2-phenylacetamide (79%). The extract exhibited the highest zone of inhibition against some pathogenic bacteria such as Enterobacter cloacae, Klebsiella pneumoniae, and Bacillus subtilis. In addition, the lowest minimum inhibitory concentration (IC) and minimum bactericidal concentration values of extract were obtained for E. cloacae (0.125 and 4 mg/ml). The extract showed antioxidant potential with IC50 values of 2.078.13±24.58 μg/ml and 475.74±4.56 μg/ml for 2,2-diphenyl-1-picryl-hydrazyl and 2,2′-azino-bis[3-ethylbenzothiazoline-6-sulphonic acid] assays, respectively. The ferric reducing antioxidant power value of extract was 110.36±1.75 mmol FeSO4.7H2O/g extract.Conclusion: This study indicated that S. omiyaensis extract possesses antibacterial and antioxidant activities. GC-MS analysis revealed the presence of major chemical constituents, acetamide, and pyrrolopyrazine which could be responsible for the biological activities. S. omiyaensis extract could be used as a potential of natural antibacterial and antioxidant agents for pharmaceutical and medical applications.

Abstract An easy, simple, and efficient analytical method was validated for the determination of residues of fipronil and its metabolites in different vegetables comprising brinjal, cabbage, capsicum, cauliflower, okra, and tomato. The Quick, Easy, Cheap, Rugged and Safe method was used for the extraction and cleanup of fipronil and its metabolites on these vegetables. Final clear extracts of ethyl acetate were concentrated under vacuum and reconstituted into acetone, and residues were determined by GC/MS with an Rtx-5 capillary column. The retention times of desulfinyl, sulfide, fipronil, sulfone, and amide were 11.8, 15.8, 16.4, 19.7, and 24.1 min, respectively. The average recoveries obtained for fipronil and its metabolites at different spiking levels were determined to be above 85% in all samples. The repeatability and reproducibility in different matrixes ranged from 1.36 to 5.42 and 1.75 to 4.53%, respectively, for fipronil and its metabolites. The LOQ of this method was 0.01 mg/kg and LOD was 0.003 mg/kg.
