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.
Claims13
A plant extract composition comprising:
- at least 15 weight percent surfactant, and
- at least 5 weight percent plant material, based on total weight of the plant extract composition;
- wherein the surfactant comprises each of:
- a pH-dependent surfactant comprising alkylamine alkoxylate surfactant, and
- an amide-based surfactant having the formula R4C(O) NR5R6, wherein R4, RS, and R6 are independently selected from saturated and unsaturated hydrocarbon-containing groups.
A method of extracting material from solid plant material, the method comprising:
- contacting solid plant material with liquid extraction medium comprising water, surfactant, and base, the surfactant comprising at least 0.1 weight percent pH-dependent surfactant based on total weight of the liquid extraction medium, and the liquid extraction medium having a basic pH;
- and
- after contacting the solid plant material with liquid extraction medium, lowering the pH of the liquid extraction medium to cause an emulsion of the liquid extraction medium to de-emulsify and form multiple phases, including an aqueous phase and a non-aqueous phase.
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 or portion thereof 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 at least one surfactant:
- i) partially or fully loses its ability to emulsify lipophilic and hydrophilic components in the processed plant aqueous composition, or ii) partially or fully disassociates with from the lipophilic plant material, or iii) is chemically cleaved into two or more surfactant by-products, or any combination of two or more of 1)-iii);
- and
- d) partially or fully separating the at least one surfactant from the lipophilic plant material.
