| 摘要: |
| 以广西姜黄那坡县种植的姜黄为原料,以水蒸汽蒸馏法和以石油醚为溶剂的索氏提取法,分别提取挥发油,并用GC-MS分析法对这些以不同加工途径获取的姜黄挥发油进行成分分析,比较了不同的加工办法对挥发油的加工得率、主要成分和含量的影响。研究表明:广西那坡的姜黄挥发油主要成分为:α-姜黄烯、芳姜黄酮、(-)-姜烯、β-倍半水芹烯、β-姜黄酮、α-姜黄酮、4-(1,5-二甲基-4-己烯基)-2-环己烯酮、β-没药烯。 |

| Abstract: |
| In this study,the volatile oil was extracted from Curcuma longa growing in Napo,Guangxi by using steam distillation and Soxhelt method. The chemical components of the volatile oil were analyzed by GC-MS. Effect of different methods on yield,main components and relative contents was compared simultaneously. The result shows that the main chemical constituents of the volatile oil are α-curcumene,(-)-Zingiberene,Ar-turmerone,β-Sesquiphellandrene,β-Turmerone,α-Turmerone,4-(1,5-dimethyl-hex-4-enyl)-cyclohex-2-enone,and β-bisabolene. |
