采用气相色谱-质谱联用技术(GC-MS)分别对乙醇和乙酸乙酯提取的青胡椒油树脂化学成分进行分析测定，并结合计算机检索技术对其成分进行结构鉴定，应用色谱峰面积归一化法计算各成分的相对百分含量。结果显示，在乙醇和乙酸乙酯提取的青胡椒油树脂中，共鉴定了58种化学组分，分别占质量分数的94.71%和97.36%。其中，这两种青胡椒油树脂中含量较高的成分主要有胡椒碱、石竹烯、胡椒新碱、D-柠檬烯、δ-榄香烯、石竹烯氧化物和喇叭烯氧化物(II)。

Chemical constituents of the green pepper oleoresin made from alcohol and ethyl acetate were analyzed by using the gas chromatography-mass spectrometry (GC-MC), and identified by their mass spectra, and their relative percentage was calculated from the GC peak areas. Fifty-eight compounds were identified, accounting for 94.71% and 97.36%of the total detected constituents, respectively. The major constituents identified from the two oleoresin include piperine,caryophyllene, piperanine, D-limonene,δ-elemene,caryophyllene oxide and ledene oxide-(II).
