Black pepper () is historically one of the most important spices and herbal medicines, and is now cultivated in tropical regions worldwide. The essential oil of black pepper fruits has shown a myriad of biological activities and is a commercially important commodity. In this work, five black pepper essential oils from eastern coastal region of Madagascar and six black pepper essential oils from the Amazon region of Brazil were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components of the essential oils were α-pinene, sabinene, β-pinene, δ-3-carene, limonene, and β-caryophyllene. A comparison of the Madagascar and Brazilian essential oils with black pepper essential oils from various geographical regions reported in the literature was carried out. A hierarchical cluster analysis using the data obtained in this study and those reported in the literature revealed four clearly defined clusters based on the relative concentrations of the major components.
黑胡椒（Piper nigrum L.）是历史上最重要的香料和草药之一，现在在全球热带地区都有种植。黑胡椒果实的精油表现出了多种生物活性，是一种具有商业重要性的商品。在这项工作中，通过水蒸馏法从马达加斯加东海岸地区获得了五种黑胡椒精油，从巴西亚马逊地区获得了六种黑胡椒精油，并通过气相色谱-质谱法进行了分析。精油的主要成分是α-蒎烯、柠檬烯、β-蒎烯、δ-3-蒈烯、月桂烯和β-石竹烯。对马达加斯加和巴西的精油与文献中报道的来自不同地理区域的黑胡椒精油进行了比较。利用本研究获得的数据和文献中报道的数据进行层次聚类分析，根据主要成分的相对浓度，将其分为四个明确的聚类。
