    摘要: Disclosed is a process for purifying one or more chemical constituents from plant matter using extraction with a fluid that is not a solvent, for example, with a vegetable oil. The extracted chemical constituents may then optionally be further processed by heating in order to induce desired chemical transformations. The extracted chemical constituents are also processed by concentrating at reduced pressure, for example, by distillation.
