Process without solvent, system and methods. # A process for purifying one or more chemical constituents from a plant material using extraction with a fluid that is not a solvent, for example, a vegetable oil, is disclosed. The extracted chemical constituents can then be optionally processed by heating in order to induce the desired chemical transformations. The extracted chemical constituents are also processed by concentration under reduced pressure, for example, by distillation. |
