Hash oil or cannabis oil is an oleoresin obtained by the extraction of cannabis or hashish. [1] It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. Hash oil is usually consumed by smoking, vaporizing or eating. [2]
Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate.The solubility of THC in ethanol is greater than 1 g/mL. [1]According to the European Medicines Agency (EMA) cannabis tinctures (tincturea) are a type of liquid cannabis extract obtained using ethanol, water, glycerol, propylene glycol and fatty oils as extraction solvents, depending on the type of ...
It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve ...
Many companies have been using supercritical CO2 extraction for cannabis. Solventless methods, such as dry-sieve and water extraction, are natural, but don’t yield the same results as processes ...
Solvent concentrations of 25–60% are common, but may run as high as 90%. [1] In chemistry , a tincture is a solution that has ethanol as its solvent. In herbal medicine , alcoholic tinctures are made with various ethanol concentrations, which should be at least 20% alcohol for preservation purposes.
A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).
Cannabis concentrate, also called marijuana concentrate, marijuana extract, or cannabis extract, is a tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Cannabis concentrates contain high THC levels that range from 40% to over 90%, [ 1 ] [ 2 ] stronger in THC content than high-grade marijuana, which normally measures around ...
Twenty drops of chloroform (or similar solvent) are then added, and the tube is vortexed, then allowed to settle and separate into two layers. Any color that transfers into the organic layer is recorded. Marijuana (as well as a variety of other plant substances) becomes purple with the addition of the Duquenois reagent and hydrochloric acid.
