Microwave extraction technology in the extraction of natural plant active ingredients in the application
    Since 1986 Ganzler , who first reported the microwave for chemical constituents of natural products extraction, microwave extraction is widely used alkaloids , flavonoids , anthraquinone , saponins and other experimental studies . Zhou such as microwave extracted from tea polyphenols . Guo library applications such as self-designed with higher precision pressure control special microwave sample preparation system for the active ingredient in honeysuckle chlorogenic acid and chlorogenic acids extraction conditions were analyzed and compared with ultrasonic extraction were compared , the results extraction rate increased by nearly 2 percent. Shao Hai and others with microwave extraction technology of walnut oil and so on .
    2007 , Flamini Guido and other methods will be applied to the new microwave extraction of essential oils from plants and Experimental Research . Compared to conventional methods , the essential oil extracted as microwave , high oxidation mixture containing , monoterpene little . Thus, microwave heating is more effective , reflecting the time-saving, energy-saving advantages. Lucchesi Marie and other studies of cardamom essential oil solvent extraction . Multi-parameter study the formation of a central composite design to assess the impact of cardamom seeds solvent extraction of essential oils of three performance variables. Statistics provided by the charge-coupled device test results show that the choice of parameters: extraction time, microwave radiation and seed moisture content are very critical.
