【摘要】:目的建立HPLC-MS法同時(shí)測(cè)定六神丸中9種蟾蜍二烯內(nèi)酯類化合物(和蟾蜍他靈、沙蟾毒精、遠(yuǎn)華蟾毒精、去乙酰華蟾毒它靈、蟾毒它靈、華蟾毒它靈、蟾毒靈、華蟾酥毒基和脂蟾毒配基)的方法。方法采用ODS-2(250 mm×4.6mm,5μm)色譜柱,以乙腈-0.15%磷酸水溶液為流動(dòng)相,梯度洗脫,體積流量1 mL/min,柱溫40℃,檢測(cè)波長296 nm。HPLC-MS聯(lián)用的色譜條件與HPLC分離基本條件一致,流動(dòng)相為乙腈-0.2%甲酸水溶液。通過電噴霧離子源,正離子模式掃描,對(duì)六神丸中9種蟾蜍二烯內(nèi)酯類化合物進(jìn)行分析鑒別。結(jié)果 9種蟾蜍二烯內(nèi)酯類化合物均得到良好分離,線性關(guān)系良好(r≥0.999 6)。加樣回收率均在92%~105%,RSD5%。應(yīng)用建立的HPLC-MS方法測(cè)定了10批六神丸中9種蟾蜍二烯內(nèi)酯類化合物的量,分別為和蟾蜍他靈0.40~0.88 mg/g,沙蟾毒精0.32~0.83 mg/g,遠(yuǎn)華蟾毒精0.61~2.11 mg/g,去乙酰華蟾毒它靈0.15~0.32 mg/g,蟾毒它靈0.84~1.85 mg/g,華蟾毒它靈25.76~62.14 mg/g,蟾毒靈0.96~2.06 mg/g,華蟾酥毒基2.30~4.75 mg/g,脂蟾毒配基1.20~2.61 mg/g。結(jié)論所建立的定量測(cè)定方法簡(jiǎn)便、快速、準(zhǔn)確可靠,專屬性強(qiáng),可用于六神丸的質(zhì)量控制。
