川白芷不同品种(系)挥发油成分GC-MS分析

目的:运用GC-MS技术比较川白芷不同品种(系)挥发油的组分和含量.方法:采用乙醇超声法,对8个川白芷品种(系)进行处理,以水蒸气蒸馏方法提取挥发油;运用GC-MS技术对各品种(系)挥发油组分进行分析,采用面积归一法计算其相对百分含量.结果:8个供试品种(系)挥发油中共鉴定出78个化合物,主要含醇类和碳烯类化合物;8个品种(系)挥发油中分别鉴定出40,33,36,38,38,42,33,36种组分,共有组分为12种.除B-6品系外,共有组分均占挥发油总量的50％以上.试验结果还表明,仅B-7品系挥发油中含较高含量吡嗪类化合物.结论:川白芷不同品种(系)挥发油组分和含量总体一致,但也存在一定差异,这为川白芷资源进一步合理开发利用提供了科学依据.

GC-MS Analysis of Essential Oil from Different Varieties (Strains) of Angelica dahurica var formosana

Objective: To compare the chemical components of essential oil from different varieties (strains) of Angelica dahurica var. farmosana by GC-MS. Method: Eight varieties (strains) of A. dahurica were treated with ethanol ultrasonic. The essential oil was extracted by water steam distillation. The component of essential oil was analyzed by GC-MS. The relative percentage content was calculated by using peak area normalization method. Result: 78 compounds were identified in eight varieties (strains) A. dahurica, mainly including alcohol and alkenes. Eight varieties (strains) of A. dahurica identified 40, 33, 26, 38, 38, 42, 33, 36 compounds, respectively. 12 compounds contained in all common compositions were accounted for over 50% of the total essential oil except B-6.Pyrazines were contained only in B-7. Conclusion: The compositions and content of essential oil are consistent in general, but there are also some differences. It provides some scientific basis for further development and utilization of A. dahurica.
