The flavor, nutritional, and medicinal value of rosemary are well known. Hydrodistilled (HD) essential oil was prepared in the present study as a standard. Olive oil maceration (OM) and supercritical carbon dioxide (SC-CO) technology were separately applied to extract the essential oil of rosemary. The three obtained products, HD, OM, and SC-CO, were compared concerning their main constituents using GC‒MS. Their antimicrobial properties were evaluated against eight microbes by the disc diffusion assay. Interestingly, both 1,8-cineol and camphor were the major compounds in the three oils. α-Pinene was also detected in large amounts in both HD and OM. Additionally, borneol was the third major component in SC-CO. The antimicrobial results revealed differential effects against six microbes. However, HD oil also exhibited antifungal activity. Maceration is a green extraction procedure that is easy to perform in households, and attention must be paid to olive oil maceration as a complementary medicine that originated in pharaohs.
迷迭香具有独特的风味、营养价值和药用价值。本研究以水蒸馏（HD）精油为标准，分别采用橄榄油浸渍（OM）和超临界二氧化碳（SC-CO）技术提取迷迭香精油。采用 GC-MS 对三种获得的产品（HD、OM 和 SC-CO）的主要成分进行比较。采用纸片扩散法评估它们对八种微生物的抗菌性能。有趣的是，1,8-桉树脑和樟脑是这三种油的主要化合物。α-蒎烯在 HD 和 OM 中也大量存在。此外，龙脑是 SC-CO 的第三大成分。抗菌结果显示对六种微生物有不同的影响。然而，HD 油也表现出抗真菌活性。浸渍是一种绿色提取方法，易于在家庭中进行，必须注意到橄榄油浸渍是一种起源于法老的补充药物。
