The gas-liquid chromatographic determination of beta-asarone (cis-2,4,5-trimethyoxy-1-propenylbenzene) in wine was collaboratively studied by 9 analysts. The samples were first distilled and then extracted into hexane prior to chromatography. The mean recovery for 8 spiked samples, analyzed as blind duplicates, was 89.27%. The reproducibility coefficient of variation was 17.9%, and the repeatability coefficient of variation was 8.3%. No unfavorable remarks were noted. The method has been adopted as official first action.
9位分析人员共同研究了气相色谱法测定葡萄酒中β-细辛脑（顺式-2,4,5-三甲氧基-1-丙烯基苯）的方法。样品先进行蒸馏，然后在色谱分析前用己烷萃取。对8个加标样品进行双盲分析，平均回收率为89.27%。再现性变异系数为17.9%，重复性变异系数为8.3%。未发现不利评价。该方法已被采用为官方首次行动方法。
