Cymbopogon citratus (DC.) Stapf., commonly known as lemon grass and used, over many years, for medicinal purposes in West Africa, produces a volatile oil on steam extraction of its leaves. The antibacterial properties of the essential oil have been studied. These activities are shown in two of the three main components of the oil identified through chromatographic and mass spectrometric methods. While the alpha-citral (geranial) and beta-citral (neral) components individually elicit antibacterial action on gram-negative and gram-positive organisms, the third component, myrcene, did not show observable antibacterial activity on its own. However, myrcene provided enhanced activities when mixed with either of the other two main components identified.
柠檬草（学名：Cymbopogon citratus (DC.) Stapf.），通常被称为柠檬香草，多年来在西非被用于药用，其叶子经水蒸气蒸馏可提取出挥发油。人们已对该精油的抗菌特性进行了研究。通过色谱和质谱法鉴定出的该精油三种主要成分中的两种表现出了这些活性。虽然α-柠檬醛（香叶醛）和β-柠檬醛（橙花醛）成分各自对革兰氏阴性菌和革兰氏阳性菌都有抗菌作用，但第三种成分月桂烯本身并未表现出可观察到的抗菌活性。然而，月桂烯与其他两种已鉴定出的主要成分中的任何一种混合时，都会增强活性。
