建立了加热振荡提取-气相色谱-质谱法（GC-MS）测定滤棒中两种特征香味成分柠檬烯、薄荷醇含量的方法。将滤棒1.0~1.5 g剪成5~10 mm的样品小段，置于100 mL锥形瓶中，加入20 mL无水乙醇和0.1 mL 50 g·L^-1苯甲酸正丙酯（内标）溶液，于30℃加热振荡提取10 min，提取液经0.45 μm有机滤膜过滤。采用HP-Innowax毛细管色谱柱（30 m×0.25 mm，0.25 μm）和选择离子监测（SIM）模式，通过GC-MS测定样品中柠檬烯、薄荷醇的含量，内标法定量。结果显示：柠檬烯、薄荷醇标准曲线的线性范围均为0.01~2.00 g·L^-1，检出限（3s）为0.12 mg·L^-1和0.05 mg·L^-1；对同一滤棒样品连续测定5次，柠檬烯和薄荷醇测定值的相对标准偏差（RSD）为2.7%和1.2%；对实际样品进行低、中、高等3个浓度水平的加标回收试验，两种特征香味成分的回收率为91.2%~106%。以凝胶释香滤棒为研究对象，其生产过程中柠檬烯、薄荷醇测定值的批次内RSD （n=50）分别为4.0%~12%和1.4%~2.2%，批次间RSD （n=6）为11%和1.9%；对不同加香载体的滤棒进行研究，结果表明凝胶释香滤棒的持香能力更好。

A method for determination of 2 characteristic aroma components (limonene and menthol) in filter rod by gas chromatography-mass spectrometry (GC-MS) with heating oscillation extraction was established. Filter rods of 1.0-1.5 g were cut into sample segments of 5-10 mm, and then placed in a 100 mL conical flask. 20 mL of ethanol and 0.1 mL of 50 g·L^-1 propyl benzoate (internal standard) solution were added. After heating oscillation extraction at 30℃ for 10 min, the extracting solution was filtered through 0.45 μm organic filtration membrane. The contents of limonene and mentol were determined by GC-MS on HP-Innowax capillary chromatographic column (30 m×0.25 mm, 0.25 μm) with SIM mode, and internal standard method was used for quantitative analysis. As shown by the results, linear ranges of limonene and menthol standard curves were in the same range of 0.01-2.00 g·L^-1, with detection limits (3s) of 0.12 mg·L^-1 and 0.05 mg·L^-1. RSDs (n=5) of the determined values of limonene and menthol on filter rod sample were 2.7% and 1.2%, respectively. Recovery test was made on substantial samples at 3 concentration levels by standard addition method, giving results of 2 characteristic flavor constituent in the range of 91.2%-106%. The filter rod containing aroma gel was used as research object, and RSDs of the determined values of limonene and menthol for intra-batch (n=50) were in the ranges of 4.0%-12% and 1.4%-2.2%, with inter-batch (n=6) of 11% and 1.9%, respectively. The filter rods with different fragrant carriers were studied, and the aroma holding capacity of filter rod containing aroma gel was better.
