【摘要】：目的建立超高效液相色譜-高分辨質(zhì)譜法(UPLC-FT/MS)同時測定類葉牡丹Cauorlhyllum robustum中9種三萜皂苷類成分的方法。方法采用正離子模式;色譜柱:ACE Excel 3 C_(18)(100 mm×2.1 mm,3.0μm);保護柱:ACE Excel 3C_(18)(12.5 mm×4.6 mm,3.0μm);流動相為0.1%甲酸水(A)-乙腈(B)溶液,梯度洗脫,體積流量0.40 m L/min,柱溫35℃。結(jié)果定量分析的類葉牡丹中三萜皂苷類成分在考察的濃度范圍內(nèi)呈良好的線性關(guān)系(r0.996);加樣回收率和RSD分別在98.49%~107.03%和1.00%~3.33%。結(jié)論本研究建立的同時測定類葉牡丹中9種三萜皂苷類成分的UPLC-FT/MS定量分析方法靈敏度高、分辨率高、質(zhì)量穩(wěn)定并且簡便、準確,可為綜合評價類葉牡丹的質(zhì)量提供參考。
