Cannabis products modified by removing volatile organic compounds and adding volatile unsaturated hydrocarbons |
Purified and modified Cannabis products and methods for producing the same. The purified Cannabis product comprises substantially no volatile organic compounds while retaining Total Potential cannabinoid content. The modified Cannabis product comprises a purified Cannabis product modified by at least one added volatile unsaturated hydrocarbon. The modified Cannabis product is formed by extracting a volatile organic compound from a Cannabis raw material to form a purified Cannabis product, and then adding the at least one volatile unsaturated hydrocarbon to the purified Cannabis product to form the modified Cannabis product and cause an enhanced user experience during combustion and inhalation of the modified Cannabis product |

Process for manufacturing cannabidiol |
process for producing cannabidiol from hemp and cannabis plants is disclosed. The steps of the process include the steps of: plant conditioning and size reduction, infusing with an extraction agent, separating a solid biomass and a liquid phase, treating the liquid phase with a removal agent, decarboxylation, removal of impurities; and color removal. The resulting cannabidiol conversion efficiency is over 90% and a TCH content within the legal limits for commercial cannabidiol. |

Cannabis oil extracts and compositions |
The present invention provides cannabis oil extracts and compositions thereof, including cannabis oil compositions containing vitamin E, and methods for preparing the extracts and compositions. In some embodiments, the present invention provides a method for preparing a cannabis oil extract comprising eluting cannabinoids from cannabis plant material with a solvent to produce an eluate, filtering the eluate with a filter to produce a filtrate, evaporating the solvent from the filtrate with a distiller to produce a distillate, and purging the distillate under conditions sufficient to remove residual solvent, thereby preparing the extract. In some embodiments, the method further includes mixing a quantity of vitamin E with the extract to produce a cannabis oil composition. |

Process for producing refined oils from botanical plant matter using a supercritical fluid |
An improved process for producing refined oils free of contaminating waxes, resins, and lipids from botanical plant matter using an improved in-line winterization process is disclosed. The biomass is fed into an extraction vessel where the oils are extracted using a solvent, followed by a two-stage separation. Both the temperature and pressure of the solvent going into the separators are controlled for effective separation. Additional solvent is added to enhance the separation efficiency between the refined oil and the undesired fraction containing the contaminants. This process provides an alternative to current wax mitigation techniques, such as alcohol based solvent winterization. |

Industrial Cannabis sativa l. extraction and purification preparation method |
The invention discloses an industrial cannabis sativa l. extraction and purification preparation method. The method comprises the following steps: step 1, taking 1/3 or more of leaves at the upper endof an industrial cannabis sativa l. plant; step 2, heating an industrial cannabis sativa l. CBD extracting solution obtained in the step 1; step 3, refrigerating the saturated CBD extracting solutionobtained in the step 2; step 4, refining a CBD extracting solution desolventized in the step 3, and removing tetrahydrocannabinol and part of impurities in crude oil by adopting a chromatographic separation technology; and step 5, crystallizing the CBD extracting solution refined in the step 4 to obtain a CBD solid. According to the industrial cannabis sativa l. extraction and purification preparation method, CBD purification can be effectively achieved through the arrangement of the first step to the fifth step, and compared with a multi-concentration mode adopted in the prior art, the method does not need of repeated heating, can effectively save energy, and is in favor of energy conservation and environmental protection. |
