Abstract

Ongoing advancements in essential oil extraction technologies have greatly improved the efficiency, environmental sustainability, and quality of phytochemical recovery from aromatic plants. Conventional extraction techniques, such as steam distillation and hydrodistillation, remain widely used, but they often lead to the degradation of heat-sensitive compounds and produce relatively low yields. In contrast, modern approaches, including supercritical fluid extraction (SFE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), and subcritical water extraction (SWE), offer more efficient, selective, and environmentally friendly alternatives. These innovative methods improve extraction performance by preserving the structural integrity of bioactive compounds and improving the accuracy of phytochemical profiling. Detailed analyses of essential oils obtained using these advanced techniques have identified a broad spectrum of biologically active constituents, including monoterpenes, sesquiterpenes, and phenolics, essential for their therapeutic and industrial value. This review explores the evolution of essential oil extraction technologies, highlighting the link between extraction method and phytochemical yield, and emphasizing the crucial role of technological innovation in optimizing the potential of volatile plant compounds.
