Cymbopogon schoenanthus (L.) Spreng. (Poaceae) is an aromatic plant whose aerial parts and rhizome produced an essential oil with pleasant odor. A chemical variability has been observed depending of the countries where the plant grows wild, including Algeria. The chemical compositions of 24 oil samples isolated from plants harvested in Central Algeria have been investigated, to evidence homogeneity or chemical variability within a given area of harvest. Twenty of these were dominated by cis‐ and trans‐p‐menth‐2‐en‐1‐ols (22.6 %±3.6 and 14.3 %±1.7, resp.) beside four atypical compositions. Otherwise, aerial parts and rhizomes produced similar essential oils. Lastly, a fair antimicrobial activity was measured against Staphylococcus aureus strain, while the antioxidant potential was low.

阿尔及利亚中部香茅精油的成分、化学变异性和生物活性

Cymbopogon schoenanthus (L.) Spreng。（禾本科）是一种芳香植物，其地上部分和根茎产生具有宜人气味的精油。根据植物野生生长的国家（包括阿尔及利亚）的不同，观察到了化学变异性。已经研究了从阿尔及利亚中部收获的植物中分离出的 24 个油样的化学成分，以证明给定收获区域内的同质性或化学变异性。除了四种非典型成分外，其中 20 种主要是顺式和反式对薄荷醇 2-en-1-ols（分别为 22.6 %±3.6 和 14.3 %±1.7）。否则，地上部分和根茎产生类似的精油。最后，对金黄色葡萄球菌菌株具有相当的抗菌活性，而抗氧化潜力较低。
