Isolation of herbal and cannabinoid medicinal extracts

摘要

Extracts of Cannabis are prepared by processes utilizing a time-sensitive partial extraction wherein the solvent is allowed to contact the Cannabis plant material for a period of time less than that needed to reach an equilibrium of dissolved cannabinoids in solvent. Such time-sensitive selective partial extraction may also be utilized with other medicinal plants having elevated levels of soluble therapeutic components in plant surface structures or near-surface structures.
