EXTRACTION OF PLANT MATERIAL Enzyme-assisted extraction (EAE) In some plants, some phytochemicals in their matrices are dispersed in cell cytoplasm, and secondary metabolites are retained in the polysaccharide-lignin network by hydrogen or hydrophobic bonding and are not accessible with a solvent extraction process Enzymatic pre-treatment has been considered Water chestnuts are found across Europe, Asia, and In vitro experimental study was carried out to evaluate antimicrobial effects and phytochemical screening of Rumex abyssinicus, Cucumis pustulatus, Discopodium penninervium, Lippia adoensis, Euphorbia depauperata, Cirsium englerianum, and Polysphaeria aethiopica against MDR bacteria and fungi. After 3 days, the mixture is pressed or strained by filtration. Extraction yield of conventional solvent extraction methods are usually high but the usage of solvents in these techniques limits the application of the extracted phytochemicals in foods as solvents may pose harmful effects when ingested (Selvamuthukumaran and Shi, 2017). Multiple solvents have been commonly used to extract phytochemicals, and scientists usually employed a dried powder of plants to extract bioactive compounds and eliminate the interference of water at the same time. Solvents used for the extraction of biomolecules from plants are chosen based on the polarity of the solute of interest. Two colored rice, Red Jasmine rice (RJM, red rice) and Hom-nin rice (HN, black rice), were Plant yield and quantitative spectrophotometric phytochemical analysis. Phytochemical Extraction Methods. Besides UV, other detection methods are also being employed to detect phytochemicals among which is the diode array detector (DAD) coupled with mass spectrometer (MS) (Tsao and Deng, 2004). This review includes a brief description of a wide range of different assays.
