气相色谱法测定莪术挥发油中榄香烯含量
Determination of element in essential oil from curcuma by GC
【摘要】 以SE-30毛细管色谱柱为分析柱,正十六烷为内标物质,采用程序升温气相色谱法测定莪术挥发油中榄香烯的含量。在榄香烯质量浓度为0.50~3.00 mg/mL范围内呈线性关系,线性方程为Y=0.899 6C-0.000 7(r=0.998 8),加样回收率为104.3%,日内及日间精密度RSD≤5.00%(n=5)。
【Abstract】 The determination method is used with SE-30 as capillary column,and n-hexadecane as internal standard by temperature programming of GC.The method has good linearity with the concentration range 0.53.00 mg· mL-1,linear equation Y=0.899 6C-0.000 7(r=0.998 8),the average recovery with added sample 104.3%,and within-day precision and day to day precision bellow 5% (n=5).The results show that elemene is separated well and its retention time is shortened.
