| 中文摘要: |
| 采用GC-MS联用技术结合程序升温保留指数首次对山东平邑产徐长卿的不同药用部位的挥发油成分进行定性定量分析.共定性出29种挥发性化学成分，地下部分（根及根茎）15种，地上部分（茎和叶）22种，分别占二者挥发油总含量的99.64%和96.51%，共有组分８种.徐长卿地下和地上部分的挥发油主要成分为丹皮酚和邻羟基苯乙酮，其中邻羟基苯乙酮为新发现的主要化合物.二者中丹皮酚的含量分别为88.45%和66.30%，邻羟基苯乙酮的含量分别为8.89%和16.99%.徐长卿地下部分的挥发油含量比地上部分多，二者存在显著性差异. |
| 英文摘要: |
| The essential oils from different parts of Cynanchum paniculatum (Bge.) Kitag were analyzed by GC/MS in combination with temperature-programmed retention indices (PTRIs) for the first the time.In all,29 compounds were identified.Among them,15 components from the volatile oil of the below-ground part of Cynanchum paniculatum (CP),and 22 ones from that of the over-ground part of CP.The common constituents between the test samples were eight.The major constituents in the below-ground and over-ground parts of CP were Paeonol and o-Hydroxyacetophenone,in which the contents of Paeonol were respectively 88.45% and 66.30%,and those of o-Hydroxyacetophenone were respectively 8.89% and 16.99%.By comparison of oil contents of the two,the oil content of the below-ground part was larger than that of the over-ground one,which had significant disparity. |
