摘　　要：[Objective] This study aimed to investigate the differences in chemical composition of supercritical CO2 extraction products in peels of Trichosanthes kirilowii Maxim. from Changqing district. [Method] Supercritical fluidextraction （SFE） and GCMS method were applied to determine and analyze the chemical components of the extracts in peels of three strains of Trichosanthes kirilowii Maxim. [Result] The chemical components of supercritical CO2 extraction products in peels of three strains of Trichosanthes kirilowii Maxim. varied., and the number of chemical components with normalized percentage content higher than 1% was 5, 7 and 8, respectively. There are 14 kinds of common components, and the relative content of hexadecanoic acid was the highest. [Conclusion] Supercritical CO2 extracts in peels of different strains of Trichosanthes kirilowii Maxim. contain different chemical components, providing scientific basis for breeding excellent varieties and the development and utilization of Trichosanthes kirilowii Maxim.[目的]探讨长清产栝楼果皮超临界CO2萃取物的化学成分含量差异。[方法]对3个品系栝楼果皮进行超临界CO2萃取,并采用GC-MS法分析其化学成分。[结果]3个品系栝楼果皮超临界CO2萃取物的化学成分有差异,归一化百分含量大于1%的化学成分数目分别为5、7、8个;共有成分14种,棕榈酸相对含量最高。[结论]栝楼品系不同果皮超临界CO2萃取物的化学成分有差异,提示选育优良品系是提高瓜蒌皮药材质量的途径之一。
