摘 要:應用化學(xué)計量學(xué)二階校正方法結合三維熒光光譜技術(shù)可以實(shí)現人血清樣中西酞普蘭、氟西汀和帕羅西汀含量的直接、快速同時(shí)測定。設定熒光激發(fā)波長(cháng)范圍為210~260 nm,發(fā)射波長(cháng)為270~388 nm,測定不同樣本的三維熒光光譜,構建三維響應數陣。當選取體系組分數為4時(shí),采用PARAFAC方法得到的血清樣中西酞普蘭、氟西汀和帕羅西汀的加標回收率(95%置信區間)分別為95.9±3.22%、104.5±8.17%和96.4±5.15%,并采用品質(zhì)因子和橢圓置信區間測試對結果進(jìn)行了進(jìn)一步驗證。實(shí)驗結果表明,該方法快速簡(jiǎn)便,解析結果可靠,無(wú)需樣本預處理,能直接用于同時(shí)分析人血清中西酞普蘭、氟西汀和帕羅西汀的含量。 |

Abstract:A novel and effective approach was developed for the simultaneous determination of citalopram(CIT),fluoxetine(FLU)and paroxetine(PAR)in human plasma samples by the incorporation of excitation-emission fluorescence(EEM)and second-order calibration method based on the parallel factor analysis(PARAFAC)algorithm. The scanning range of their excitation and emission wavelengths were set at 210~260 nm and 270~380 nm,respectively. The obtained 95% confidence interval of CIT,FLU and PAR in human serum samples by using PARAFAC method with an estimated component number of four were 95.9±3.22,104.5±8.17 and 96.4±5.15%,respectively. Moreover,the accuracy of the method was also evaluated through elliptical joint confidence region(EJCR)tests as well as the figures of merit. The experimental results demonstrated that the method has been satisfactorily applied to determination of CIT,FLU and PAR in human serum samples without previous separation procedure. |
