目的比较橘白(Album Citri Reticulatae,ACR)与橘络(Cylindricae Citri Reticulatae,CCR)挥发油成分的异同。方法采用GC-MS进行检测,通过交互移动窗口因子分析法对重叠峰进行解析,实现ACR与CCR挥发油成分的定性、定量比较分析。结果 ACR与CCR分别定性出30和32种化合物,分别占挥发油总含量的92.03%和94.28%。两者有24个共有化合物,分别占到ACR与CCR挥发油总含量的89.38%和92.04%。结论 ACR与CCR挥发油成分在物质种类上差异较小,但各物质在含量上有明显差异。 Objective To compare the similarities and differences between the essential oil components of Album Citri Reticulatae (ACR) and Cylindricae Citri Reticulatae (CCR). Methods The GC-MS was used to detect the overlapped peaks by using the cross-correlation window method. The qualitative and quantitative comparative analysis of the components of the volatile oil from ACR and CCR were carried out. Results 30 and 32 compounds were identified by ACR and CCR, accounting for 92.03% and 94.28% of the total volatile oil respectively. There are 24 common compounds in both, accounting for 89.38% and 92.04% of the total content of the volatile oil of ACR and CCR, respectively. Conclusion There is no significant difference in the types of volatile oil between ACR and CCR, but the contents of ACR and CCR are obviously different.
