Essential oils (EO) are volatile compounds with complex chemical compositions that are derived from the secondary metabolism of aromatic herbs. There are several applications of EO in the industrial and medical sectors. Basil (Ocimum sp.) is one of the most important EO-producing aromatic herbs. In this study, EO content (EOC) and linalool content (LC) in basil irrigated with reclaimed water were investigated. Plant development parameters, nutrient absorption and crude protein (CP) content were also evaluated. The experiment was conducted in a greenhouse, with five different treatments and five repetitions each. Compared with treatments only using water, the results of those with reclaimed water irrigation showed higher nutrient absorption, CP contents (in their foliar tissue), length of plant branches, foliar biomass weights, and EOC and LC. EOC reached up to 0.58% of the dry biomass and LC was up to 5.84% of EO mass. In practice, it is estimated that around 5.8 kg of EO and 0.34 kg of linalool can be obtained from one ton of dry basil biomass.

精油 (EO) 是具有复杂化学成分的挥发性化合物，来源于芳香草本植物的次级代谢。EO 在工业和医疗领域有多种应用。罗勒（罗勒sp.) 是最重要的产生 EO 的芳香草本植物之一。在这项研究中，研究了用再生水灌溉的罗勒中的 EO 含量 (EOC) 和芳樟醇含量 (LC)。还评估了植物发育参数、养分吸收和粗蛋白 (CP) 含量。实验在温室中进行，有五个不同的处理，每个处理五次。与仅用水处理相比，再生水灌溉的结果显示出更高的养分吸收、CP 含量（在其叶组织中）、植物分枝长度、叶生物量重量以及 EOC 和 LC。EOC 达到干生物量的 0.58%，LC 达到 EO 质量的 5.84%。在实践中，估计从一吨干罗勒生物质中可以获得约 5.8 kg EO 和 0.34 kg 芳樟醇。
