Abstract

The essential oils from the aerial parts of leaves, fruits and flowers of Zanthoxylum rhoifolium of Southern Brazil (Rio Grande do Sul), were analysed by GC, GC/MS, and chiral phase gas chromatography (CPGC). Forty-eight compounds were identified from the essential oils. The major constituents of the essential oil of the leaves were germacrene D (34 %) and bicyclogermacrene (23 %) and of the fruits, menth-2-en-1-ol (46.2 %), beta-myrcene (30.2 %), (-)-linalool (15 %) and (-)-alpha-terpineol (8.45 %). beta-Myrcene (65 %) and menth-2-en-1-ol (5.4 %) dominate the essential oil of the flowers. The oils of the leaves and fruits were bioactive with antibacterial activity against Staphylococcus aureus (Gram positive), and Klebsiella pneumoniae and Salmonella setubal bacteria (Gram negative) microorganisms, while the essential oil of the flowers was inactive.

摘要

对巴西南部（南里奥格兰德州）的刺花椒叶、果实和花朵地上部分的精油进行了气相色谱（GC）、气相色谱/质谱联用（GC/MS）和手性相气相色谱（CPGC）分析。从精油中鉴定出48种化合物。叶精油的主要成分是杜松烯D（34%）和双环杜松烯（23%），果实精油的主要成分是薄荷-2-烯-1-醇（46.2%）、β-月桂烯（30.2%）、（-）-芳樟醇（15%）和（-）-α-松油醇（8.45%）。β-月桂烯（65%）和薄荷-2-烯-1-醇（5.4%）在花精油中占主导地位。叶和果实的精油具有生物活性，对金黄色葡萄球菌（革兰氏阳性）、肺炎克雷伯菌和塞图巴尔沙门氏菌（革兰氏阴性）微生物具有抗菌活性，而花精油没有活性。
