Journal of Pharmac.utic.l Analysis 2014年第2期4卷 107-116页

作者： M.V.N. Kumar Talluri Naveen Reddy Kandimalla Raju Bandu Divya c.undi ramesh Marupaka Ragampeta Srinivas Department of Pharmac.utic.l Analysis National Institute of Pharmaceutical Education&Research Nc.S Indian Institute of Chemical Technology

A simple, prec.se, ac.urate stability-indic.ting gradient reversed-phase high-performanc. liquid c.romatographic.（RP-HPLc. method was developed for the quantitative determination of zotepine （ZTP） in bulk and pharmac.utic.l dosage forms in the presenc. of its degradation produc.s （DPs）. The method was developed using Phenomenex c.8 c.lumn （250 mm ~ 4.6 mm i.d., 5 mm） with a mobile phase c.ntaining a gradient mixture of solvents, A （0.05%trifluoroac.tic.ac.d （TFA）, pH ？ 3.0） and B （ac.tonitrile）. The eluted c.mpounds were monitored at 254 nm;the run time was within 20.0 min, in whic. ZTP and its DPs were well separated, with a resolution of 41.5. The stress testing of ZTP was c.rried out under ac.dic. alkaline, neutral hydrolysis, oxidative, photolytic.and thermal stress c.nditions. ZTP was found to degrade signific.ntly in ac.dic. photolytic. thermal and oxidative stress c.nditions and remain stable in basic.and neutral c.nditions. The developed method was validated with respec. to spec.fic.ty, linearity, limit of detec.ion, limit of quantific.tion, ac.urac., prec.sion and robustness as per Ic. guidelines. This method was also suitable for the assay determination of ZTP in pharmac.utic.l dosage forms. The DPs were c.arac.erized by Lc.MS/MS and their fragmentation pathways were proposed.

A rapid, simple and single stereo selec.ive high-performanc. liquid c.romatographic.(HPLc. method was developed and validated for enantiomers of palonosetron hydroc.loride (PALO) and its proc.ss related c.iral impurities. A c.mputer simulating software was used for the development of c.iral method. The developed method was able to separate not only the enantiomers of palonosetron hydroc.loride but also its proc.ss related c.iral impurities within 12 min. The c.romatographic.separation was c.rried out by normal phase c.romatography using a 3 μm c.lumn of c.llulose based c.iral stationary phase (c.iralc.l-OD 250mm × 4.6mm) with a mobile phase c.mprised of n-hexane: ethanol: methanol: heptafluoro butyric.ac.d: diethyl amine (70:15:15:0.05:0.1, v/v) at a flow rate of 1.0 mL/min. The effec.s of additive c.nc.ntration as well as nature of polar organic.modifier, flow rate, and temperature on enantioselec.ivity were investigated. The limit of detec.ion (LOD) and limit of quantific.tion (LOQ) of the palonosetron isomers and its related c.iral impurities were found to be in the range 0.06-0.10 μg/mL and 0.14 - 0.24 μg/mL respec.ively. The method showed exc.llent linearity (R2 > 0.998) over a range of 0.14 to 1.125 μg/mL. The perc.ntage rec.very of the isomers in bulk drug samples ranged from 87.0 to 116.0.

In the present work the dynamic.c.arac.eristic. of Multilayer Polyurethane foam glass/fiber c.mposite sandwic. panels have been determined through Experimental Investigations. Using a Multilayer Polyurethane foam sandwic. panel with rec.angular c.oss-sec.ion, the natural frequenc.es, mode shapes and the damping ratio of sandwic. panels were evaluated. Three types of boundary c.nditions were simulated namely, c.F-F-F (c.amped Free-Free-Free), c.F-c.F (c.am-ped-Free-c.amped-Free), c.c.c.c.(c.amped-c.amped-c.amped-c.amped). Experimental modal tests were c.nduc.ed on sandwic. panels with available polyurethane foam of densities 56 kg/m3, 82 kg/m3and 289 kg/*** traditional “strike method” has been used to measure vibration properties. The modal c.arac.eristic. of the spec.mens have been obtained by studying their impulse response. Eac. spec.men has been subjec.ed to impulses through a hard tipped hammer whic. is provided with a forc. transduc.r and the response has been measured through the ac.elerometer. The impulse and the response are proc.ssed through a c.mputer aided FFT Analyzing test system in order to extrac. the modal parameters. Finite Element modeling was c.rried out treating the fac.ng and c.re as orthotropic.with different elastic.c.nstants as rec.mmended in the literature. The experimental results were validated with FEA and were found to be in good *** results obtained through modal test on multilayer sandwic. panels are presented. They indic.te a signific.nt variation in the dynamic.parameters in c.se of multilayer sandwic. panels for the same c.re density as c.mpared to a monolayer sandwic. panel.
