Plant extraction technology is a technical means of extracting or extracting one or several active ingredients in a plant by using physical or chemical extraction means, extracting the plant according to the desired ingredients, without changing the structure of the active ingredient. At present, plant extraction methods include water extraction, organic solvent extraction, ultrasonic extraction, microwave extraction, supercritical extraction, and membrane separation.
In order to obtain high-quality plant extracts, the extraction of plant active ingredients needs to undergo multiple steps such as high temperature enzyme digestion, fragmentation, extraction, precipitation, lyophilization, and purification. At this time, the instruments and equipment that people need to use include a centrifuge, a freeze dryer, a spectrophotometer, and a high performance liquid chromatography system.
In the field of plant extraction, analytical detection technology can realize the quantitative analysis of active ingredients and harmful substances in plant extracts. In addition to our common high performance liquid chromatography, gas chromatography, GC/MS, LC/MS, atomic spectrometry and other analytical instruments and methods are also widely used in this field.
