1 mar 2023 · During the extraction process, microwaves heat the solvent and plant tissue, enhancing the kinetics of extraction. The microwaves heat the sample by directly impacting the polar molecules. The energy conversion from microwave to heat involves dipolar rotations.
17 kwi 2018 · Extraction is the first step to separate the desired natural products from the raw materials. Extraction methods include solvent extraction, distillation method, pressing and sublimation according to the extraction principle. Solvent extraction is the most widely used method.
The comparisons among different solvents such as water, methanol, ethanol, ethyl acetate, and acetone for flavonoid extractions have been reported by Mou et al. [109]. These authors found that methanol and ethanol were the most prominent solvents for extraction of flavonoids.
1 sty 2022 · An appropriate extraction technique that balances product quality, process efficiency, production costs, and environmentally acceptable methods should be used for the extraction of bioactive compounds from plant tissues.
23 sty 2022 · The preparation of a sample of plant material for analysis involves several important steps. The first step is pre-washing, drying or freeze-drying the plant material, and grinding for homogenization. The following steps are extraction and qualitative and quantitative determination [1, 2, 6].
16 lis 2022 · Novel methods like microwave extraction, supercritical fluid extraction, accelerated solvent extraction, sonication, and enzyme-assisted extraction have made the extraction process of bioactive compounds relatively easier.
