There are many common extraction methods for plant extracts, such as solvent extraction, ultrasonic extraction, microwave extraction, and enzyme extraction, and supercritical fluid extraction, microwave-assisted extraction, etc.
First of all, let’s take a look at the solvent extraction method. The principle is that we extract the effective ingredients from natural plants in their effective parts. The method of extracting the effective ingredients by using the different solubility of the ingredients in the plant in the solvent is usually in the process. It uses natural plants as raw materials. It is first crushed and put into a container, and then we add an appropriate amount of solvent to mix, and then use the processes of dipping, percolation, decoction, reflux and continuous extraction to extract the active ingredients. It is important to note that we Must choose a solvent that is miscible with the solute.
In each process of extraction, there are many factors that affect the extraction rate of effective ingredients, such as the concentration of the solvent, the ratio of material to liquid, the temperature and time during extraction, and so on.
