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 Background Recent advances in the diversified anti-diabetic drugs have appeared in the startling increase in the count of poisoning cases. The epidemics of diabetes mellitus are increasing; hence, the no. of anti-diabetic drug users raised by 42.9%. The use of glimepiride raised to 24%. As the toxicity and drug cases are also escalating with increasing epidemics of diabetes mellitus, a novel gas chromatography-mass spectrometry (GC-MS) method for detecting glimepiride in biological matrices is developed. Results Liquid-liquid extraction method was employed by using 1-butanol: hexane (50:50, v/v) under an alkaline medium, and then back extraction was done via acetic acid. Distinct derivatization techniques were employed for the sample preparation for GC-MS analysis, i.e., silylation and acylation. Derivatization approaches were optimized under different parameters, i.e., reaction temperature and reaction time. N-Methyl-N-(trimethylsilyl) trifluoroacetamide [MSTFA] was found to be the best sound derivatization reagent for the GC-MS analysis of glimepiride. Total ion current (TIC) mode was selected for the monitoring of ions of trimethylsilyl (TMS) derivative of glimepiride with an m/z ratio of 256. Distinct parameters like specificity, carryover, stability, precision, and accuracy were evaluated for validating the identification method. The GC-MS method is found to be linear and illustrated within the range 500 to 2500 ng/ml with the value of R2 (coefficient of determination) at 0.9924. The stability of the extracted and derivatized glimepiride was accessed with regard to processed/extracted sample conditions and autosampler conditions, respectively. Accuracy at each concentration level was within the + 15% of the nominal concentration. Precision (%) for the interday and intraday analysis was found to be in the respectable spectrum. Conclusion Henceforth, the proposed GC-MS method can be employed for the determination of glimepiride in biological matrices.

 Objective:The objective of this study is to characterize the phytoconstituents of Tiliacora racemosa Colebr. using gas chromatography mass spectrometry (GC-MS).Methods: Preliminary phytochemical and physicochemical analysis was carried out using standard procedures. GC-MS analysis of methanolic extract was carried out using Thermo GC-Trace Ultra version: 5.0, Thermo MS DSQ with a DB 35MS capillary standard non-polar column and gas chromatograph interfaced to a mass selective detector (MS DSQ II) with Xcalibur software.Results: Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, triterpenoids, steroids, proteins and amino acids, carbohydrates, saponins and coumarin. Quinones, anthraquinones, glycosides and fixed oil were absent. GC-MS analysis revealed the presence of 28 compounds of which quinic acid (retention times [RT]: 15.65) and inositol, 1-deoxy-(CAS) (RT: 19.24) was observed as abundant compounds.Conclusion: The presence of various bioactive compounds confirms the medicinal importance and it’s application for curing various diseases by traditional practitioners. However, isolation and characterization of potential bioactive compounds would lead to drug formulation.
