Ethyl acetate extracts of secondary metabolites, whose activity was determined, were fractionated. purified. The antimicrobial 5 of the fully or partially purified GGI-4B fraction. Efficacy doses Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBK) values ​​were used in the test. For this purpose, each different group was tested again. Mueller Hinton (MHB), Brain Heart Infusion (BHI), and Malt are suitable for microorganisms. MIC values ​​were determined by dilution method (96) using extract (MEB) liquid culture media. MBC values ​​were determined in well microplates and then by culture method. 10 The invention relates to approximately 5 g of ethyl acetate produced at two separate times from the F. oxysporum YP9B strain. The extract was obtained using column chromatography with hexane, chloroform, ethyl acetate, methanol, etc. Purification was performed using different solvents and at different gradients. The collected materials... The fractions were subjected to Thin Layer Chromatography (TLC normal phase silica gel 60 F254), 15 The process was carried out in different solvent environments. A cabinet was used to control thin-layer decomposition. A 254 nm UV lamp located inside was used. UV control of inactive compounds. For this, acid is sprayed onto the ITK plate, followed by a burning process on a hot plate. NMR spectra were obtained from the fractions that were treated and thought to be pure. CDCl3 and Adeton-d6 were used as solvents during the process. 20 After fractionation by column chromatography, the active extract was separated from the normal extract. or repeated analysis with isocrotic mobile phase system by reverse phase (C8 or C18) HPLC method Chromatographic analysis of phenolic or other compounds was performed using the previously developed method. The study was conducted using a Shimadzu brand HPLC instrument. A Zorbax 25 was used as the analytical column. Eclipse XDB-C8 (150 mm × 4.6 mm, 5µm) or similar columns were used. Isocrotic mobile. The phase was adjusted to have a suitable gradient, and repeated HPLC was run. Column oven. The temperature was set to 40 °C. The HPLC system has an existing photodiode array detector. HPLC analysis was performed using a wavelength of 280 nm. 14 The isolated active natural metabolite was analyzed using 400 MHz NMR (1H, 13C, APT / DEPT and 2D NMR). methods), UV, FT-IR and mass spectroscopy (such as EI, LC-TOF, LC / MS-MS, GC-MS) It was characterized by its methods. 1H and COSY NMR spectra are relative to the TMS peak, while 13C and APT spectra are relative to acetone-d6 5. The values ​​were adjusted according to the solvent peaks of (δ 206.7, 30.7 ppm) and CDCl3 (δ 77.0 ppm). The spectra were obtained using the electron spray (ES) method. Column chromatography (CC) and thin-layer chromatography (TLC) were used for isolation. In column chromatography (CC), the normal phase uses 230-400 mesh silica gel, while the thin layer is 10 In the chromatography (TC) of the thin layer, normal phase silica gel 60 F254 was used. A 254 nm UV lamp located inside the cabinet was used to monitor separations, or ITK acid spraying onto the plate and subsequent burning process on a hot plate. It has been implemented. Gas Chromatography and Gas Chromatography Mass Spectrometry (GC and GC / MS) In these studies, the fatty acids obtained were converted into fatty acid methyl esters, thus altering their composition. It has been analyzed. The electron catcher detector used in the mass spectrometer was captured. The ionization of ions is 70 eV. The device used has a film thickness of 60 m × 0.25 mm id. A capillary column (0.25 µm) was used. The flow rate of helium used as the carrier gas was 1 20 The injection rate is mL / min. Injection was performed in splitless mode at 230 °C. From the prepared samples... The resulting volatile components were placed in the column at 60 °C for 2 minutes, then incrementally increased by 3 °C. It was run at temperatures up to 240 °C. The structure of volatile components in each sample was determined by comparing retention indices (RI) of 25 Retention indices were attempted to be determined for fatty acid methyl ester components. Spectral data for all volatile components were determined using (C4-C24) standards. Library of mass spectra of the instrument (NIST and Wiley 7NL) (Adams, 2004), standards (FAMEs; C4-C24) and compared with sources in the literature. Analyzed twice. The peak areas of the samples were calculated using correlation factors. 30 Preparation of fatty acid methyl esters; Preparation of Fatty Acid Methyl Esters (FAMEs) First, 5 mL of 5% NaOH solution is added to 100 mg of sample and incubated at 60-70 °C. The samples were left to stand for 3-4 hours. 5 mL of methanol was then added to the cooled samples in an ice bath. The samples were placed in the test tubes and BBr3 was added drop by drop. The test tubes were incubated in a water bath at 100 °C for 6 hours. The samples were heated for an hour and then cooled. 3 mL of water was added to each sample, which was then divided into 2 mL portions. It was extracted twice with hexane. The resulting hexane phases were dried with Na2SO4, The samples were filtered, and fatty acid methyl esters (FAMEs) were obtained from the samples after the organic solvents were evaporated. It has been obtained. 15 16 REFERENCES Wang, QX, Li, SF, Zhao, F., Dai, HQ, Li, CS, Ding, R., Gao, H., Zhang, LX, Liu, H. (2011). Chemical constituents from endophytic fungus Fusarium oxysporum.
