Stevia compositions are prepared from Stevia rebaudiana Bertoni extracts. The compositions are able to provide a superior taste profile and can be used as sweeteners, sweetness enhancers, flavors, flavor enhancers in foods, beverages, cosmetics and pharmaceuticals.

Materials and methods for extracting and purifying proteins are provided. For example, the materials and methods provided herein can be used for extracting and purifying proteins that denature at low temperature.

The present invention provides a composition having functionality to enhance immunity. Differing from all commercial vitamin healthcare foods would cause some adverse effects due to excessive vitamin intake, the present invention proposes a Solanum nigrum-fermented product to be a novel composition having functionality to enhance immunity. Moreover, animal experimental results have proved that, this novel composition would not cause any adverse effects (such as poor appetite or liver damage) even if an adult excessively administer the novel composition. In addition, comparing with the commercial healthcare foods always being made to tablets, the Solanum nigrum-fermented product (i.e., the novel composition) can be processed to various forms, such as powder, tablet, capsule, and drink.

The present invention relates to the use of a brown Flammulina velutipes extract for inhibiting acute kidney injury caused by cisplatin. With the water extract of brown Flammulina velutipes, which reduces the renal histological changes, the production of creatinine, blood urea nitrogen in the acute kidney injury caused by cisplatin.

The present specification discloses a composition for external application to skin, containing a tea plant root extract as an active ingredient, for treatment of skin damage caused by fine dust, whereby the expression level of one or more selected from a group consisting of IL-36G (NM_019618), S100A7 (NM_002963), S100A8 (NM_002964) and XDH (NM_000379), which are genes in skin cells the expression level of which is affected by fine dust, is regulated to a normal level.

Methods and processes for efficiently extracting cannabinoids from cannabis are described together with cannabis extracts obtained using such methods. A method may include: preparing a premixture by mixing dried cannabis with an extraction agent; incubating the premixture; and after incubating the premixture, adding a liquid to the premixture to create a liquid mixture and filtering the cannabis from the mixture.

The invention relates to methods of separating or isolating a component from a plant using freeze separation. The invention includes products produced by said methods.

The invention relates to a method for obtaining a composition based on conifer bark enriched in dihydroquercetin or in tannins, comprising the following steps: a) grinding dried shavings of bark from a conifer to obtain a ground particulate material of conifer bark, and b) selecting, from the ground particulate material obtained in step a), the fraction of particles: of smallest size representing at most 40% by weight, relative to the total weight of the ground particulate material obtained in step a), this fraction being enriched in tannins; or of largest size representing at most 50% by weight, relative to the total weight of the ground particulate material obtained in step a), this fraction being enriched in dihydroquercetin.

The invention relates to an aqueous extract of rosewood, preferably rosewood from summer roses, obtained by enzymatic extraction using a cosmetically acceptable polar solvent, a process for producing same, and uses thereof, particularly as an agent for preventing and/or reducing the signs of aging on the skin.

The present invention is a process for producing various types of cannabis extract from harvested cannabis. A quantity of harvested cannabis, which typically includes the inflorescence, floral leaves, and small stems of a flowering cannabis plants, is pre-frozen. The harvested cannabis is first subjected to cryogenic grinding to produce pulverized cannabis. The pulverized cannabis is then subjected to alcohol extraction to produce an initial cannabis extract, which can be subjected to one of several forms of further processing according to the desired chemical profile of the final product. The initial cannabis extract may then be subjected to chemical processing that promote the conversion of THCA to Δ9 THC; the conversion of THCVA to THCV; the conversion of THCA to cannabinol (“CBN”); or the conversion of THCA to Δ8-THC.
