摘　　要：采用毛细管气相色谱对4种中成药中2-莰醇的质量分数进行了快速测定.结果表明:分析时间4 min,当内标物与2-莰醇的质量比为1∶0.25～1∶1时,峰面积比与质量比呈线性关系,线性方程为y＝0.517 8x+0.076 8,相关系数r＝0.995 4.平均校正因子为1.562 5,样品平均回收率92.72%,样品分析相对标准偏差值1.05%～2.55%.The mass fractions of bomeol in 4 traditional Chinese medicines were quickly determined with capillary gas chromatography. Results were as follows： Analyzing time was 4 minutes. When the proportion of concentrations of internal standard and bomeol was within 1 ： 0.25 - 1 ： 1, ratio of peak square and ratio of concentration had a linear relation and linear equation was y = 0.517 8x ＋ 0.076 8, the correlation coefficient r being 0.995 4. The average correction factor was 1.562 5; the average recovery rate of the extract was 92.72% and the RSD was 1.05%-2.55%. [Ch, 1 fig. 3 tab. 9 ref.]
