醫(yī)學(xué)論文范文:RPHPLC法測定溫腎蘇拉甫片中嗎啡的含量
【摘要】 目的:以溫腎蘇拉甫片為研究對象,建立對罌粟殼中所含嗎啡的含量測定方法。方法: 采用RPHPLC法:SHIMADZUPack VPODS 色譜柱(4.6×150 mm,5 μm),流動相為甲醇-乙腈-0.5%醋酸銨溶液-三乙胺(12.5∶12.5∶75∶0.06),流速1.0 ml/min,檢測波長為287 nm,柱溫:35℃,進(jìn)樣量:10 μl。結(jié)果:嗎啡在21.8~436.0 μg/ml濃度范圍內(nèi)呈良好的線性關(guān)系(r=0.999 7,n=5);平均回收率低、中、高濃度分別為:96.99%、97.55%、100.17%,相應(yīng)的RSD值分別為:0.52%、0.37%、0.33%(n=9)。供試液穩(wěn)定性日內(nèi)和日間RSD分別為:0.80%、0.89%。最小檢測限為0.72 μg/ml。結(jié)論:本方法專屬性強(qiáng)、操作簡單、靈敏度高、結(jié)果準(zhǔn)確、重現(xiàn)性好,可用于制劑的質(zhì)量控制,同時完善并提高了原有的藥品質(zhì)量標(biāo)準(zhǔn)。

Abstract: Objective: To develop an RPHPLC method for determination morphine content in compound tablets. Methods: By RPHPLC. The liquid chromatography was carried out using a SHIMADZUPack VPODS column (4.6×150 mm, 5 μm). The flow rate of the mobile phase: methanolacetonitrile 0.5% ammonium acetatetriethylamine (12.5∶12.5∶75∶0.06) was 1.0 ml/min. Detection wavelength was at 287 nm, column temperature was at 35℃, the injection volume was 10 μl. Results: The linear response range of morphine was 21.8~436.0 μg/ml (r=0.999 7, n=5). The average recovery was not less then 96.99%, RSD was less then 0.33% (n=9). The RSD for interday and intraday were all less then 0.80% (n=6). Detectable concentration limited was 0.72 μg/ml. Conclusion: The method is simple, sensitive, accurate and reproducible. It can be used in quality control of Wenshensulafu compound tablets.

溫腎蘇拉甫片為新疆地方標(biāo)準(zhǔn)維藥,其主要成分有中亞白及、肉豆蔻、高良姜、附子、肉豆蔻衣、肉桂、罌粟殼、西紅花等[1-2]。該方的原質(zhì)量標(biāo)準(zhǔn)方法簡單,又因罌粟殼所含的主要生物活性成分為嗎啡類生物堿,歸屬于麻醉藥品,連續(xù)使用易產(chǎn)生身體依賴性,能成癮癖,嗎啡是罌粟殼中含量最大的毒性成份,致死量為100 mg,極量為30 mg。可待因是罌粟殼中另一毒性成分,僅為嗎啡毒性的1/8。罌粟堿對人的致死量為100~500 mg,由此可見控制罌粟殼的毒性主要是控制嗎啡的含量,這是建立嗎啡的含量測定方法和規(guī)定毒限的依據(jù)。本文主要以HPLC法對嗎啡及罌粟堿進(jìn)行含量測定,方法簡便、重現(xiàn)性好,結(jié)果準(zhǔn)確可靠,與其它分析方法比照,結(jié)果甚為滿意醫(yī).學(xué).全.在.線zxtf.net.cn。
