摘要:
The present invention includes methods for preparing resveratrol, resveratrol esters and substituted and unsubstituted stilbenes of the formula given below; where each Y is —O or halogen, each Z is —O or halogen, each n and each m is independently the value of 0, 1, 2, 3, 4 or 5, each A and each B is independently selected from Pn, R or absent, each V and each W is independently selected from Pn, straight or branched alkyl of from 2 to 6 carbon atoms and cycloalkyl of from 3 to 8 carbon atoms, alkoxy, phenyl, benzyl or halogen, R is independently selected from the group comprising alkyl with at least one carbon atom, aryl and aralkyl, Pn is an alcohol protecting group and diastereoisomers of the foregoing. The compounds are made from a multi-step process including a N-heterocyclic carbene-type ligand coupling in the presence of a base with benzyol halide and styrene coupling partners. These compounds show increased stability for use in the food, cosmetic and pharmaceutical industries.
摘要:
A method for producing an ester polyol, comprising transesterifying a first ester polyol with a primary polyol to produce a second ester polyol, wherein the second ester polyol has a higher hydroxyl value than the first ester polyol.
摘要:
The present invention generally concerns a process for the purification of crude glycerol obtained as a by-product of industrial processes such as saponification, hydrolysis and transesterification with low chain alcohols of natural oils and fats. The present invention particularly concerns the purification treatment of crude glycerol obtained as a by-product of the biodiesel production from vegetable oils and animal fats, aiming to obtain a concentrated purified product.
摘要:
A preventive or therapeutic agent for diseases accompanied by insulin level or insulin response disorder, characterized in that at least one compound selected from the group consisting of chalcone compounds, acetophenone compounds, coumarin compounds, phthalide compounds, derivatives of these and pharmacologically acceptable salts thereof is contained as an active ingredient. There are further provided an insulin-like agent; a food, beverage or feed; a promoter of glucose introjection in cells; and an agent capable of inducing differentiation to lipocytes.
摘要:
A therapeutic agent and prophylactic agent for a disease accompanying an abnormality in an amount of insulin or insulin response, an agent for an insulin-mimetic action, a food, beverage and feed, an agent for enhancing glucose uptake into a cell, and an agent for inducing differentiation into an adipocyte, characterized in that each comprises as an effective ingredient at least one compound selected from the group consisting of a chalcone compound, an acetophenone compound, a coumarin compound, a phthalide compound, derivatives thereof, and pharmacologically acceptable salts thereof.
摘要:
The present invention relates to a fatty acid ester of an etherified polyhydric alcohol represented by the following general formula (1), a production process thereof, a cosmetic composition comprising this compound, and a production process of an etherified polyhydric alcohol via the ester.
G(A) x (B) y (1)
(G: a residue formed by removing H atoms of all the OH groups of a polyhydric alcohol having at least three OH groups, A: -CH 2 CH(OH)R or -CHRCH 2 OH, R 1 : R 1a or -CH 2 OR 1a (R 1a : C 1 -C 36 alkyl or alkenyl group), B: H or C 1 -C 11 acyl group, x + y: the number of the OH groups of G, x ≥ 1, y ≥ 1, and at least one of y groups B: acyl group). The compound (1) is not only useful as an intermediate for the production of an etherified polyhydric alcohol, but also excellent per se in the performance as a cosmetic base, emulsifier, lubricant, oily component and the like.
