誰能查SCI收錄情況?就是知道文章有沒有被收錄,沒有購買數(shù)據(jù)庫是不是不行? 如果可以幫忙查下Spectroscopy 23 (2009) 209–216 [ Last edited by chim on 2010-5-24 at 17:38 ] |

已經收錄,恭喜。 標題: Flow injection chemiluminescence determination of levofloxacin in medicine and biological fluids based on its enhancing effect on luminol-H2O2 reaction 作者: Shao XD, Li Y, Liu YQ, et al. 來源出版物: SPECTROSCOPY-AN INTERNATIONAL JOURNAL 卷: 23 期: 3-4 頁: 209-216 出版年: 2009 被引頻次: 0 更多細節(jié)如下: 作者: Shao XD (Shao, Xiaodong)1, Li Y (Li, Ying)2, Liu YQ (Liu, Yangqin)1, Song ZH (Song, Zhenghua)3 來源出版物: SPECTROSCOPY-AN INTERNATIONAL JOURNAL 卷: 23 期: 3-4 頁: 209-216 出版年: 2009 被引頻次: 0 參考文獻: 22 引證關系圖 摘要: Levofloxacin{(-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[ 1,2,3-de]-1,4-benzoxazine-6-carboxylic acid} is a synthetic fluorinated quinolone derivative, having activity against both Gram (+) and Gram (-) bacteria (aerobic and anaerobic) through inhibition of their DNA gyrase. In this paper, a simple flow injection chemiluminescence with luminol-hydrogen peroxide system was described for determining levofloxacin. The chemiluminescence intensity in the presence of levofloxacin was remarkably enhanced compared with that in the absence of it. Under the optimum reaction conditions the chemiluminescence increment produced was proportional to the concentration of levofloxacin in the range of 1.0-700.0 ng ml(-1) (R-2 = 0.9992), with a detection limit of 0.3 ng ml(-1) (3 sigma). At the flow rate of 2.0 ml min(-1), the whole process including sampling and washing could be completed in 0.5 min offering the sampling efficiency of 120 times h(-1) accordingly, and the relative standard deviation (RSD) was less than 3.0% (n = 5). The recovery for the levofloxacin samples was from 95.9% to 104.5%. It was satisfactory for the application to determine levofloxacin in pharmaceutical preparations, human urine and serum samples. 文獻類型: Article 語言: English 作者關鍵詞: Levofloxacin; chemiluminescence; flow injection; human serum and urine KeyWords Plus: PERFORMANCE LIQUID-CHROMATOGRAPHY; PHARMACEUTICAL-PREPARATIONS; GATIFLOXACIN; SPECTROMETRY; MOXIFLOXACIN; PLASMA 通訊作者地址: Shao, XD (通訊作者), China Natl Petr Corp, Tubular Goods Res Ctr, Xian 710065, Peoples R China 地址: 1.
