摘　　要：采用水蒸气蒸馏法分别提取产于甘肃岷县道地产区当归的当归身、当归尾、当归头中的挥发油,使用气相-质谱联用(GC-MS)分析其挥发油的化学组分。在相同提取测定条件下,当归不同部位提取的挥发油中各化学成分含量存在差异性,当归身、当归尾、当归头在保持较多藳本内酯的同时,均含有其他有效成分,且这些有效成分种类与含量不尽相同。提示当归不同药用部位的挥发油化学成分含量具有一定的差异,药理作用的物质基础不同,探寻当归不同部位的挥发油的化学成分变化规律,为中药当归的加工及临床应用提供科学依据。GC-MS was applied to analyze the constituents of volatile oil extracted from the body,tail and head of angelica originated from Min county in Gansu by steam distillation.Content of the constituents in volatile oil extracted from different parts of angelica varied under the same determination conditions.There were more ligustilide in angelica body,tail and head,while there were also some other effective constituents of which the types and content were different.The results suggested that content of constituents of volatile oils extracted from different medicinal parts of angelica varied,and the efficacious material basis were different.Thus,to explore the variation of constituents of volatile oil from different parts of angelica could provide scientifical refernces for angelica processing and clinical application.
