Abstract
Described are liquid compositions that contain a desired (e.g., extracted) plant material such as cannabinoid, terpene, terpenoid, or the like, contained, e.g., dissolved, suspended, or emulsified, in the liquid, which contains surfactant; methods of preparing these types of liquid compositions; and methods of processing this type of liquid composition to collect, isolate, concentrate, or purify a desired target material contained in the liquid composition.
Claims21
A plant extract composition comprising:
- at least 15 weight percent surfactant,
- at least 5 weight percent plant material,
- based on total weight plant extract composition.
A liquid extraction medium comprising water, surfactant, and base, the medium comprising:
- at least 0.1 weight percent pH-dependent surfactant,
- at least 1 weight percent amide-based surfactant,
- at least 0.001 weight percent amphiphilic, detergent-type surfactant, or
- two or more of these,
- based on total weight liquid extraction medium,
- the liquid extraction medium having a basic pH.
A method for extracting a lipophilic plant material from a plant, comprising steps of:
- a) obtaining a plant or portion thereof comprising a lipophilic plant material;
- b) processing the plant in an aqueous composition, wherein the aqueous composition has a basic pH and comprises at least one surfactant;
- c) lowering the pH of the aqueous composition wherein the surfactant i) partially or fully loses its ability to emulsify lipophilic and hydrophilic components in the processed plant composition, ii) partially or fully disassociates with the lipophilic plant material, iii) is chemically cleaved into two or more surfactant by-product, or any combination of i)-iii);
- and
- d) partially or fully separating the surfactant from the lipophilic plant material.
