目的 :分析我国中药材GAP基地红心大白菊挥发油的化学成分 ,为其质量评价提供科学依据。方法 :采用水蒸气蒸馏法提取红心大白菊挥发油 ,用GC毛细管柱进行分析 ,归一化法测定其相对含量 ,并用GC MS法鉴定化学成分。结果 :检出 136个色谱峰 ,鉴定出 4 7个化合物 ,占挥发油总量的 6 2 .2 4 %。结论 :红心大白菊挥发油中 ,雪松醇、喇叭醇和 1 (1,5 二甲基 4 己烯基 ) 4 甲基苯是其主要成分 ,以倍半萜类化合物喇叭醇含量最高 ,占总挥发油量的 13.9%。
Objective : To analyze the chemical constituents of volatile oil of Radix Rhododendi Chinensis in GAP base of Chinese herbal medicine and provide scientific basis for its quality evaluation. Methods : The steam volatile oil was extracted by steam distillation and analyzed by GC capillary column. The relative content was determined by the normalized method. The chemical components were identified by GC MS. Results : 136 peaks were detected and 47 compounds were identified, accounting for 62.4% of the total volatile oil. Conclusion: Among the volatile oils of Flos Chrysanthemi in Radix Rhizome, cedarol, horn alcohol and 1 (1,5 dimethyl-4-hexenyl) 4 methylbenzene are the main components, and the highest content of octanol is stilbenes, which accounts for the total volatile oil content. 13.9%.
