Definitions

  • the present invention is directed to advanced extraction systems and methods to extract or remove phytochemicals from plants, including those of the plant family
  • the present invention is directed to plant oil extraction and, more specifically, the use of a method and system for extracting essential oils from plants, such as cannabis, without the use of a solvent.
  • Maceration may be defined as the extraction of a compound in a solvent at ambient room temperature with daily shaking or stirring. After a selected period, the solid material is separated from the solution. Variation on the method includes agitation of the macerate and the use of temperatures up to approximately 50° C. A variation of the method includes preparation of tinctures and extracts from low-density plant material using various strengths of ethanol as a solvent.
  • Decoction has been used since antiquity for the preparation of medicines; and customarily in traditional Chinese medicine.
  • the quantity of herbs required for one day's treatment are placed into a vessel and hot or boiling water is added.
  • the vessel may be brought to a boil and allowed to simmer for one or more hours. Once cooled, solid particles are filtered out and the decoction administered orally.
  • Maceration and decoction rely on short path diffusion, where inactive constituents such as lecithins, flavonoids, glycosides and sugars act to solubilize compounds which, in a pure state, are soluble in the solvent.
  • a disadvantage of maceration and decoction with water or low concentrations of ethanol is that a large quantity of inert material typically having no therapeutic value must be removed.
  • This inert material may consist of plant cell elements including, but not limited to fats, waxes, carbohydrates, proteins, and sugars. This may contribute to microbiological spoilage of a resulting product if not used promptly or further refined or preserved in some fashion. If dried, such extracts tend to be hygroscopic and difficult to fonnulate.
  • the inert material may also affect how active phyto-elements are absorbed in and from a finished formulation.
  • Maceration and decoction are still widely used in situations where convenience outweighs precise dosage accuracy.
  • Macerate and/or percolate solvents may be removed by evaporation at temperatures below 100° C provided the correct solvent is used.
  • Solvents employed may be miscible or immiscible with water and vary in efficacy.
  • Techniques used to extract compounds from plants include liquid and solid extraction, liquid and gas chromatography and other separation and fractioning techniques.
  • Tinctures are ethanol solutions easily produced and well described in most major pharmacopoeias. Where the final concentration of alcohol is greater than approximately 20% by volume, the tincture remains microbiologically stable and widely used in compounding prescriptions. Ethanol extract substances such as glycosides, flavonoids and alkaloid salts are examples of compounds known to be biologically active. Ethanol also extracts considerable amounts of plant pigment, such as chlorophyll and carotenoids. By using higher alcohol strengths, lipid-soluble material maybe extracted. Tinctures typically contain less inert material than macerates or decoctions, but are still complex mixtures of plant chemical elements. Where alcohol is not required or desired, a tincture may be evaporated to produce ethanol free extracts.
  • Lipid solvents are also used to extract lipid soluble chemical elements from a phyto-biomass.
  • chlorinated solvents such as dichloromethane, chloroform, carbon- tetrachloride, hexane, ether, fluorinated hydrocarbons, and supercritical fluid extraction with inert agents such as carbon dioxide.
  • chlorinated solvents is highly disadvantageous for phyto-biomass extraction because of extreme toxicity; and because for medicinal or pharmaceutical use such toxic solvents must be removed by various means before administration.
  • Hexane and other petroleum-based solvents have good solvent activity; however, they must also be completely removed from any end product, and also carry the risk of fire and explosion during use.
  • temperatures e.g., ca. 15° C to ca. 230° C
