發(fā)布時(shí)間:2018-07-20 15:28
【摘要】:目的:對帕泊昔布膠囊含量測定進(jìn)行研究。方法:用高效液相色譜法(HPLC)測定,選用Kromasil C18色譜柱(250 mm×4.6 mm,5μm),流動相為乙腈:0.01 mol·L~(-1)醋酸鈉緩沖液=30∶70;流速為1.0 m L·min~(-1);檢測波長為260 nm;柱溫30℃。峰面積按照外標(biāo)法進(jìn)行計(jì)算。結(jié)果:帕泊昔布在0.004 04~0.020 19 mg·mL~(-1)范圍內(nèi)線性良好,高、中、低3個(gè)濃度加樣平均回收率分別為98.5%,99.1%和98.5%。測定3個(gè)不同批號樣品的含量分別是99.3%,99.3%和98.9%。結(jié)論:該法操作快速簡便、靈敏度高、專屬性強(qiáng),能夠克服制劑中輔料對測定結(jié)果的干擾,也可用于該膠囊制劑的質(zhì)量控制。
