A process for the extraction of oleoresins from vegetable material by solvent comprising the following successive steps:

a solvent washing step of vegetable material in maceration means controlled in temperature and/or pressure for a time varying between 10 and 60 minutes, with a proportion between the mass of vegetable material to be treated and the volume of solvent between 1:5 kg/l 1:10 kg/l; the temperature is controlled by means of a cryogenic fluid and is between −60 ° C. and −100 ° C., thus obtaining a mixture containing a solid fraction, and a liquid fraction in which the oleoresins dissolved in the solvent are included;

a pressing step of the mixture in order to separate the solid fraction of vegetable material from the liquid fraction of solvent containing the oleoresins;

a step of filtration of the liquid fraction of the mixture;

a step of separation of the solvent from the liquid fraction of the mixture in an evaporator, controlled under pressure and temperature, in which the pressure is between 10 mbar and 50 mbar and the temperature is between 10° C. and 40° C., thus obtaining so the active principles and/or the oleoresins.

A novel standardized liquid propolis extract and pharmaceutical formulation based on said extract, as well as their manufacturing methods and uses, are provided. The liquid extract is produced by extraction of crude propolis with an extraction solvent based on a mixture of PEG 200-600 (96.5-99.9% w/w) and lecithins (0.1-3.5% w/w). The extract is characterized with standardized content of p-coumaric acid (1), trans-ferulic acid (2), caffeic acid (3), and CAPE (4). It is used as an active ingredient in manufacturing of pharmaceutical, cosmetic, veterinary, agrochemical or functional food products. The pharmaceutical formulation according to the invention consists of 5-95% w/w of the said propolis extract and up to 100% excipients required for preparation of various dosage forms. It is used for treatment of diseases and conditions in humans and animals such as: inflammatory diseases, bacterial and fungal infections, viral, autoimmune and cancer diseases, and for the treatment of burns and wound healing.

A method and apparatus for extracting botanical oil from botanical mass includes milling the biomass and chilling the milled biomass. The biomass is then exposed to a chilled ethanol solvent. Water is added and the solution introduced into a first centrifuge. The clean ethanol slurry is then introduced into an evaporator leaving a two-phase mixture which is introduced into a second centrifuge which separates the water from the pure botanical oil.

The invention extends the utility of apparatus used to extract medicinal cannabis compounds into an eluate by separating a portion of medicinal cannabis compounds contained within a portion of eluate at a first extraction target level providing enough clean solvent to continue extraction operations. A high efficiency concentrator such as a rotary evaporator or a wiped film evaporator processes eluate from one or more tanks or extraction vessels creating clean solvent when extraction targets are met or when clean solvent is exhausted. This manages eluate concentration levels and limits the quantity of concentrated medicinal cannabis compounds on site at any moment in time. The invention enables a business model for keeping medicinal cannabis compounds within a legal system, and reduces pollution because law enforcement would no longer have to burn large quantities of cannabis plant matter.

A process and apparatus for extracting plant oil from plant material by cooling an alcohol solvent to a temperature of −40° C. or lower, contacting the plant material with the cold solvent to extract plant oil to provide a solvent and plant oil mixture, heating the mixture to convert the solvent to a gaseous state to thereby separate the solvent from the plant oil, and cooling the separated gaseous solvent to a liquid to recover the solvent. The apparatus may include a heat exchanger to cool the alcohol solvent, a centrifuge configured to receive and contact a batch of plant material with the cold solvent to extract oil from the plant material to provide a solvent and oil mixture, and a programmable logic controller to monitor and control the temperature of the cold solvent, and control the centrifuge to agitate the solvent in contact with the plant material.

An apparatus for extracting essential oils and oleoresins from a plant material is disclosed. The apparatus comprises a circulation pump, a discharging pump, an extraction module, a reservoir, a first evaporator, and a first condenser. The discharge pump is fluidly connected to the circulation pump. The extraction module includes at least one extraction vessel.
