【摘要】:目的建立苗藥虎耳草藥材的HPLC指紋圖譜及5種成分定量測定方法,為虎耳草質(zhì)量控制提供參考。方法采用Agilent Eclipse XDB-C18(150 mm×4.6 mm,5μm)色譜柱,以乙腈(A)-0.1%磷酸水溶液(B)為流動相,進行梯度洗脫;體積流量1.0 m L/min,檢測波長254 nm,柱溫35℃。對21批不同產(chǎn)地的虎耳草建立HPLC指紋圖譜,采用國家藥典委員會"中藥色譜指紋圖譜相似度評價系統(tǒng)(2004A)"對結(jié)果進行分析處理,并選取主要成分建立多指標測定方法。結(jié)果指紋圖譜研究所建立的方法結(jié)果良好。21批不同產(chǎn)地虎耳草的HPLC指紋圖譜中,確定11個共有峰,并指認了其中5個色譜峰,分別是原兒茶酸、沒食子酸、巖白菜素、槲皮素-5-O-β-D-葡萄糖苷和槲皮苷,21批虎耳草藥材與對照藥材的相似度差異較大。將5個指認成分作為主成分建立多指標測定方法,其線性關(guān)系良好,范圍分別為0.052 8~0.844 8、0.020 96~0.335 36、0.241 6~3.865 6、0.130 8~2.092 8和0.023 68~0.378 88μg;5種成分的回收率分別為96.64%、100.72%、96.62%、103.71%、96.75%,RSD均小于2%。21批藥材中5種成分的質(zhì)量分數(shù)分別在0.07~0.40、0.19~4.36、1.42~5.98、0.42~6.86、0.11~1.51 mg/g。結(jié)論所建立的方法簡便可靠、耐用性好,可作為虎耳草藥材質(zhì)量控制方法。
