摘 要:采用Aglient Hc-C8 5 μm 150 mm×4.6 mm色譜柱,流動(dòng)相為甲醇-0.2%乙酸溶液,梯度洗脫,流速為1 mL/min,280 nm為檢測波長(cháng),建立了測定環(huán)合反應液中呋喃酚含量的高效液相色譜分析方法。在進(jìn)樣量為8.0~24.0 μg的范圍內線(xiàn)性關(guān)系良好(Y=464.539 4X+56.170 2,r=0.999 9),RSD 0.5%,回收率99.6%~100.5%,分析周期為30 min。方法快速、簡(jiǎn)便、準確,可用于環(huán)合反應中的呋喃酚質(zhì)量控制。
關(guān)鍵詞:呋喃酚;梯度洗脫;HPLC;環(huán)合反應液

Abstract:A HPLC method was established for determination of 2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuranol in cyclization solution. The HPLC system consisted of Aglient Hc-C8 column(5 μm,4.6 mm×150 mm),methanol﹕0.2% acetic acid solution as mobile phase for gradient elution at flow rate of 1 mL/min,the detective wavelength 280 nm,and column temperature 30℃. The result showed that the peak area(Y)of 2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuranol had a good linear correlation with the injection mass(x)in the range of 8.0~24.0 μg,and its linear equation was Y=464.5394X+56.170 2,r=0.999 9,RSD was 0.5%,recovery was 99.6%~100.5%,and analysis period was 30 min. The method was proved to be sensitive,fast and accurate,and could be suitable to the quality control of 2,3-dihydro-2,2-dimethyl-7-hydroxy -benzofuranol in cyclizing solution .
Key words:2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuranol;gradient elution;HPLC;cyclizing solution
