1. A method of extracting one or more bioactive agents from biomass, the method comprising:
blending the biomass and the one or more bioactive agents;
continuously passing the biomass though one or more microwave assisted extraction units, thereby exposing the biomass to microwave energy; and
separating the one or more bioactive agents from the biomass using the one or more microwave assisted extraction units that use the polarity of water in the subcritical range in lieu of chemical solvents to extract the one or more bioactive agents from the biomass.
