EXTRACTION TECHNOLOGIES FOR MEDICINAL AND AROMATIC PLANTS. Most of the active ingredients present in the form of natural organic compounds. ) leaves were compared: maceration, maceration under sonication, infusion and supercritical fluid extraction. Conventional approaches for the extraction Medicinal plants besides therapeutic agents are also a big source of information for a wide variety of chemical constituents which could be developed as drugs with precise selectivity. The results obtained indicated that these two traditional extraction methods could effectively extract antioxidants from medicinal plants. The products so obtained from plants are relatively complex mixtures of metabolites, in liquid or semisolid state or (after removing the solvent) in dry powder form, and are intended for oral or external use. A group of medicinal plants possessing nutritious and tonic functions were chosen as model plants. 1. Interest in Microwave-Assisted Extraction (MAE) has increased significantly over the past 5-10 years in particular medicinal plant research, as a result of its inherent advantages as special heating mechanism, moderate capital cost and its good performance under atmospheric conditions [13, 14]. One supports the highly scientific method of standardization, which involves measuring and extracting specific compounds believed to be responsible for the herbs’ medicinal effects. Extraction First steps in the process of screening medicinal plants for antifungal activity is extraction. nutans) is a well-known medicinal plant in South-East Asia that has been traditionally used for treatment of hepatitis, skin-rashes and snake venom poisoning, and recently has attracted attention for its applications for treatment and prevention of Saponins, Steroids and Phytosterol were obtained after extraction had been conducted from these traditional medicinal plants. g.
