摘　　要：选用正十二烷为内标物,采用内标法对α-蒎烯、β-蒎烯、对伞花烃和长叶烯进行了定量分析。确定了最优的气相色谱分析条件,分别测定了α-蒎烯、β-蒎烯、对伞花烃和长叶烯的相对质量校正因子和线性回归相关系数。用内标法和面积归一法分别对试样进行了定量分析,结果表明两者误差小于2.33%。A method was introduced for quantitative analysis of α-pinene, β-pinene, p-cymene and longifolene by 1102-Gas Chromatograph with the n-dodecane as internal standard. The optimal conditions for GC analysis were confirmed and the relative mass correction factors and the linear correlation coefficients of α-pinene, β-pinene, p-cymene and longifolene were determined. Internal standard method and area nomalization method were used to determine the sample, respectively and the result showed that the relative error was less than 2.33 %.
