| TITLE： | |
| 摘要： | 目的：比较山东莱阳、河北安国、内蒙古赤峰3个产地北沙参挥发油成分的差异。方法：采用水蒸气蒸馏法提取不同产地北沙参挥发油并计算提取率。利用气质联用（GC-MS）技术分析挥发油成分，采用Xcalibur工作站对数据进行校正，采用NIST 11.0质谱数据库进行化合物检索（匹配度＞800），以峰面积归一化法求得各化学成分的相对质量分数。结果：莱阳北沙参的挥发油提取率为0.013％，远低于安国北沙参（0.099％）和赤峰北沙参（0.105％）。分别从3个产地北沙参挥发油中鉴定出了15、18、27个化合物，相对质量分数分别为89.29％、96.76％、94.53％；镰叶芹醇是不同产地北沙参挥发油中相对质量分数最高的共有化合物，相对质量分数分别为69.79％、90.89％、71.04％；莱阳产北沙参富含脂肪酸类成分，安国和赤峰产北沙参富含C15H24型倍半萜类成分。结论：不同产地北沙参的挥发油成分有较大差异，提示应将其作为区分不同产地北沙参的化学标志物。 |
| ABSTRACT： | OBJECTIVE： To compare the difference in volatile oil constituents of Glehniae littoralis from 3 producing areas as Shandong Laiyang， Hebei Anguo， Inner Mongolian Chifeng. METHODS： The method of steam distillation was used to extract the volatile oil of G. littoralis from different areas and calculate the extraction rate. The constituents of volatile oil were analyzed by using GC-MS. The data was corrected by Xcalibur chemical workstation. The constituents were searched by NIST 11.0 mass spectrometry database （matching degree ＞800）， and the relative mass fraction of each chemical constituent was obtained by peak area normalization. RESULTS： The extraction rate of volatile oil in G. littoralis from Laiyang was 0.013％， which was far lower than G. littoralis from Anguo （0.099％） and G. littoralis from Chifeng （0.105％）. There were 15， 18 and 27 constituents identified in volatile oil of G. littoralis from 3 producing areas； the relative mass fractions were 89.29％， 96.76％， 94.53％. Falcarinol was a common compound with the highest relative mass fraction of the volatile oil of G. littoralis from different producing areas； the relative mass fractions were 69.79％， 90.89％ and 71.04％， respectively. Fatty acids were rich in the sample from Laiyang， while C15H24 sesquiterpenoids were rich in the other samples from Anguo and Chifeng. CONCLUSIONS： Volatile oil of G. littoralis could be used as potential chemical markers to distinguish different producing areas due to their significant differences in chemical components. |
