摘　　要：本文利用香叶天竺葵的叶片,对香叶天竺葵中香茅醇的提取率进行研究。对提取香茅醇的最适乙醇浓度、温度、时间、料液比分别进行了测定。结果表明,乙醇提取法的最佳工艺条件为乙醇浓度75%、温度40℃、时间4 h、料液比1∶20的最佳组合,在该条件下香茅醇提取率可达0.88 mg/g。The extraction rate of citronellol from leaves of Pelargonium graveolens were determined.The optimum ethanol concentration,temperature,time,and solid-liquid ratio for extracting the citronellol were examined.The results of statistical analysis showed that the ideal extraction condition was as follows： 75 % ethanol concentration,40 ℃,4 h,and 1∶ 20 of the solid-liquid ratio.Under this condition,the extraction rate of citronellol from leaves of Pelargonium graveolens was 0.88 mg/g.
