The present specification discloses methods of purifying one or more cannabinoids from a plant material, purified cannabinoids and pharmaceutical compositions comprising one or more cannabinoids produced by the disclosed method, methods and uses for treating a disease or condition employing such purified cannabinoids and pharmaceutical compositions.

In some examples, a filter assembly may include a filter including a first gasket having a first channel adjacent to a first side of the filter and a second gasket having a second channel adjacent to a second side of the filter. The first gasket and the second gasket may include a beveled surface adjacent to the filter. The first channel and the second channel may include a diameter of from about 0.01 mm to about 0.5 mm. A finger tightening system may securely hold the filter without any leaks.

Embodiments of a method of purifying a lysophosphatidylcholine (e.g., LPC-DHA and/or LPC-EPA) from a composition containing the lysophosphatidylcholine and at least one impurity, e.g., from phospholipids, free fatty acids, triacylglycerols (TAGs), diacylglycerols (DAGs), monoacylglycerols (MAGs), glycerol, sterols, tocopherols, vitamin A, flavonoids, and minerals can use a continuous simulated moving bed process, a batch column chromatography method, or a single column to provide a purified composition of the lysophosphatidylcholine. The purified lysophosphatidylcholine (e.g., LPC-DHA and/or LPC-EPA) products can be used in various pharmaceutical and nutraceutical applications, e.g., for treating and/or preventing a neurological disease or disorder.

This disclosure relates to a process which involves: (a) providing an aqueous solution of a protein and a polyalkoxy fatty acyl surfactant of formula I

##STR00001##

wherein R.sup.1—C(═O) is a fatty acyl group, R.sup.2 is H or a substituted or unsubstituted hydrocarbyl group, X.sup.1 is O or NH, X.sup.2 is O or NH, n is 0 or an integer of 1-5, R.sup.3 is a polymeric group comprising polymerized units of formula II and III,

##STR00002##

and (b) subjecting the aqueous solution to a bioprocess.

This invention relates to a method for the preparation of lithium carbonate from lithium chloride containing brines. The method can include a silica removal step, capturing lithium chloride, recovering lithium chloride, supplying lithium chloride to an electrochemical cell and producing lithium hydroxide, contacting the lithium hydroxide with carbon dioxide to produce lithium carbonate.

Systems and methods for extracting useful by-products and natural rubber from non-Hevea rubber bearing plants are disclosed.

Systems and methods for extracting useful by-products and natural rubber from non-Hevea rubber bearing plants are disclosed.

Methods and systems for recovering high-value target ions such as lithium ions from a brine solution, wherein a target-ion-selective adsorbent material (such as bound or unbound adsorbent particles) are mixed with the brine solution to form a slurry, and the slurry is contacted with a filter to capture target-ion-enriched material, which target-ion-enriched material is then contacted with a stripping solution to separate the target ions from the target-ion-enriched material.

[Problems] To provide a method for treating hydroxyapatite filler so that it can be used multiple times in the separation of a charged material included in a sample liquid using adsorbent composed of the hydroxyapatite filler, a production method including the treatment method, and hydroxyapatite filler.

[Means to solve problems] The treatment method of the present invention comprises a first step of bringing a first liquid containing a predetermined material into contact with hydroxyapatite filler, and a second step of bringing a second liquid containing an alcohol into contact with the hydroxyapatite filler.
