摘 要:目的分别用对照品法和对照提取物法测定岗松油中α-蒎烯、β-蒎烯、桉油精和芳樟醇的含量,探讨选择对照提取物替代单体对照品测定岗松油含量的可行性。方法采用DB-5气相毛细管色谱柱(60 m×0.25 mm×0.25μm);程序升温:起始温度80℃,保持15 min,1℃/min升至90℃,保持2 min,10℃/min升至110℃,25℃/min升至240℃,保持8 min;进样口温度250℃;检测器温度250℃。结果α-蒎烯、β-蒎烯、桉油精和芳樟醇在各自的浓度范围内均有良好的线性关系(r≥0.999),平均回收率为96.5%~102.2%;t检验表明2种测定方法得出的含量结果无明显差异。结论对照提取物法可用于岗松油的质量评价。Objective To determinate the contents of α-pinene, β-pinene, eucalyptol and linalool in Baeckea frutescens by reference substances method and reference extract method respectively; To explore the feasibility of replacing single component reference by control extracts in assay. Methods The GC system consisted of a quartz column DB-5(60 m×0.25 mm×0.25 μm); The temperature programming rose from 80 ℃(15 min) to 90 ℃ by 1 ℃/min, lasting 2 min, then 10 ℃/min to 110 ℃, then 25 ℃/min to 240 ℃, lasting 8 min in the end; The temperature of the entrance of capillary vessel column was 250 ℃, and the temperature of the detector was 250 ℃. Results α-pinene, β-pinene, eucalyptol and linalool were in a good linear relationship within each concentration scope(r≥0.999). The average recovery rates were in the range of 96.5%–102.2%. The results of t-test demonstrated that there is no significant difference between the two methods. Conclusion The reference extract method can be used as a quality evaluation pattern for Baeckea frutescens.
