Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.

Provided is a process of stabilizing active ingredients of plant materials in an aqueous suspension, the process including: extracting one or more active ingredients of a plant material using an extraction solvent, wherein the extraction of the one or more active ingredients of the plant materials comprises: transferring the plant material into a temperature-controlled reactor; adding the extraction solvent to the temperature-controlled reactor, thereby producing an eluant from the plant material; incubating the eluant at a first selected temperature for a pre-determined duration of time; and running the eluent through a filtration process to obtain an extractant solution filtrate and a separated solid plan material product; encapsulating the one or more active ingredients in one or more nanoparticles; and dispersing the one or more nanoparticles in an aqueous suspension.

A method of purifying cannabis derived terpenes includes first providing cannabis material having a detectable amount of tetrahydrocannabinolic acid (THCA), adding a solvent to the cannabis material, spinning the cannabis material in a centrifuge to separate crystallized THCA from a high terpene extract. Decarboxilating the THCA with heat to yield tetrahydrocannabinol. The high terpene extract is deposited into a vacuum oven to reduce pressure and volatilize terpenes from the high terpene extract. Next the terpenes are pumped into a cold trap to condense terpenes from the high terpene extract. Next, the condensed terpenes are cooled at a temperature between −50° C. and 0° C. to remove water from the condensed terpenes and yield purified terpenes. The purified terpenes are applied to an edible food product containing decarboxylated tetrahydrocannabinol. In an alternate embodiment, the tetrahydrocannabinol and the purified terpenes are combined or recombined and mixed directly into a precooked edible food product.

The present invention concerns a method of extracting and refining wax from plant material. Briefly, the method comprises the steps of (a) providing plant material comprising cuticular wax, (b) disassociating cuticular wax from the plant material by subjecting said plant material to a dry mechanical treatment and suspending the dry mechanically treated material, or a fraction thereof, in an aqueous solution comprising protease and/or pectinase enzymes, thereby obtaining a sample comprising plant derived cuticular wax and dewaxed plant material in an aqueous suspension, (c) solubilizing the plant derived cuticular wax by increasing the temperature of the sample, (d) separating the suspension into a solid fraction and a liquid fraction comprising melted plant derived cuticular wax, (e) adjusting the pH and temperature of the liquid fraction to pH 5.5 or lower and 50° C. or lower, respectively, (f) separating the mixture into a waxy fraction and an aqueous fraction, (g) recovering the plant derived cuticular wax from the waxy fraction.

Provided are a method for producing a purified Salacia genus plant extract having improved flavor by increasing the α-glucosidase inhibitory activity of the extract without significantly reducing the recovery rate of the extract concomitantly with purification; and a purified Salacia genus plant extract. The method for producing a purified Salacia genus plant extract includes an extraction step of bringing a Salacia genus plant-containing raw material extract including at least one of a Salacia genus plant, a Salacia genus plant extract, and a Salacia genus plant ground product, into contact with 0.1 to 20 mass % of activated carbon in the presence of an extraction solvent.

A method for preparing a tar extract with aroma characteristics from a discarded cigarette butt includes: (1) adding the discarded cigarette butt to an extraction solvent, and carrying out subcritical fluid extraction to obtain an extraction solution; (2) carrying out vacuum filtration on the extraction solution, and carrying out vacuum distillation on the filtrate to obtain a concentrated extractum; and (3) carrying out molecular distillation on the concentrated extractum, and collecting a light fraction of the molecular distillation to obtain the tar extract with aroma characteristics. Through the subcritical fluid extraction and separation by the molecular distillation to prepare the tar extract, harmful substances in the tar are removed, and the aroma components are retained. The tar extract is applied to a cigarette to improve the aroma, smoke and taste characteristics of the cigarette.

A Luer lock includes a tapered female member and a tapered male member defining a passage. A tubing is inserted through the passage. The tubing defines an outer cross-section corresponding to an inner cross-section of the passage. The tapered male member is configured to be inserted into the tapered female member such that the tube is in fluid communication with the tapered female member, and the tubing exerts a compressive force at a mating surface between the tapered male member and the tapered female member to increase friction therebetween and inhibit leakage. The male member may define a side port defined on a side wall thereof. The side port may provide an additional fluid pathway for application of vacuum or pressure through the tapered male member.
