Comparative Studies on Different Extraction Methods of
Maceration is a technique in which plant materials are soaked in a solvent at a specific temperature and time . The extract from this method is concentrated using a rotary evaporator to obtain the final solvent-free crude extract.
A review of modern and conventional extraction techniques and …
Mar 1, 2023 · Maceration is preferably carried out in a stoppered container to minimize solvent loss through evaporation. It is undesirable to obtain an already concentrated extract through evaporation of the solvent during the extraction process.
Maceration - an overview | ScienceDirect Topics
The maceration process is an ancient technique in which the whole or selected parts of a vegetable sample (or other natural extracts) are kept in contact with a specific solvent, for a certain period of time, which can range from some hours to days, at room or higher temperatures.
Comparative evaluation of maceration, microwave and ultrasonic …
Aug 16, 2019 · In this study different extraction methods (maceration, ultrasonic and microwave) were analysed in order to establish the suitable method for the extraction of bioactive compounds from six different propolis samples using ethanol/water (70/30, v/v) mixture.
revealed the importance of appropriate maceration periods in combination with different extraction solvents used, in giving a satisfactory and reliable result on the antimicrobial activity of the nine potent microorganisms.
Maceration, Percolation and Infusion Techniques of Extraction …
A piece of filter paper is placed on surface followed by a layer of clean sand so that top layers of drugs are not disturbed. Sufficient menstruum is poured over the drug slowly and evenly to saturate it, keeping the tap at bottom open for passing of occluded gas to pass out.
The Art of Extraction: A Step-by-Step Guide to the Maceration …
Aug 22, 2024 · Place a filter paper or a fine-mesh sieve over a container and pour the macerated liquid through it. Use gentle pressure or a stirring rod to help the liquid pass through the filter. The filtered liquid is now the extract, which contains the desired compounds.
Extraction Methods, Quantitative and Qualitative Phytochemical
Aug 2, 2022 · A gram of sample is extracted repeatedly with 100 mL of 80% aqueous methanol. The mixture is filtered through Whatman no.1 filter paper into a pre-weighed 250 mL beaker. The filtrate is transferred to a water bath and allowed for evaporation to dryness and followed by weighing off the sample .
Plant Extraction Methods - SpringerLink
Nov 16, 2022 · The classical techniques of plant extraction like maceration, percolation, Soxhlet extraction are used in ‘small-scale’ manufacture or research settings. Novel methods like microwave extraction, supercritical fluid extraction, accelerated solvent extraction, sonication, and enzyme-assisted extraction have made the extraction process of ...
