568367000 | Plural alicyclic rings containing | 11 |
20080293975 | Method of Recovering Xanthophyll - The present invention provides a method for collecting xanthophylls, the method comprising an adsorption step of contacting a sample containing xanthophylls with a hydrophilic resin to allow the resin to adsorb the xanthophylls; and a desorption step of eluting the xanthophylls adsorbed to the resin with a polar solvent. Preferably, the method comprises a step of washing the resin between the adsorption step and the desorption step. As the resin, a hydrophilic, acrylic and/or methacrylic resin is preferably used. | 11-27-2008 |
20100174118 | PROCESS FOR PRODUCTION OF CAROTENOID - A method for producing a composition containing carotenoid at a content of 80% or greater, characterized in performing extraction on a culture of a microorganism, a concentrate of the culture, or a dried substance thereof with at least one selected from the group consisting of lower alcohols, water-containing lower alcohols, lower dialkylketones and ethers; and then washing a precipitate, obtained by concentrating the extract solution, with at least one selected from the group consisting of lower alcohols, water-containing lower alcohols, hydrocarbon-based solvents and lower dialkylketones; and food, a pharmaceutical composition or a cosmetic substance comprising the carotenoid-containing composition. | 07-08-2010 |
20110021843 | PRODUCTION OF CAROTENOIDS IN OLEAGINOUS YEAST AND FUNGI - The present invention provides systems for producing engineered oleaginous yeast or fungi that express carotenoids | 01-27-2011 |
20140221694 | CRYSTAL FORMS OF ASTAXANTHIN - The invention describes previously undisclosed crystal forms of astaxanthin designated crystal form I and II. It has been surprisingly found that the two crystal forms of astaxanthin show an improved bioavailability, a relatively high solubility in specific organic solvents and an increased long-term stability. For example the new forms are stable in solid form for at least 90 days at a temperature of 20° C.-40° C. It was further found that the two crystal forms can be prepared from each other. Therefore the invention also relates to methods for preparing said crystal forms. In addition, the invention relates to administration forms (hereinafter also called “formulations”) comprising one of the two crystal forms according to the invention or mixtures thereof dissolved or suspended in oil or organic-solvent. | 08-07-2014 |

20150133693 | METHODS OF CONVERTING MIXTURES OF PALMITOLEIC AND OLEIC ACID ESTERS TO HIGH VALUE PRODUCTS - The invention describes methods and systems for making particular organic compounds from unsaturated fatty acids derived from biological materials. Particular embodiments describe synthesizing civetone and olefins from a mixture of palmitoleic and oleic unsaturated fatty acid esters. The inventive methods use reaction steps such as metathesis, cyclization, hydrolysis, and/or decarboxylation. | 05-14-2015 |
20160016874 | METHOD OF SYNTHESIS - Described is a method of synthesizing 6-(5-ethoxyhept-1-yl)bicyclo[3.3.0] octan-3-one by reacting 3-(5-ethoxyhept-1-yl) cyclopentene with dichloroketene. The resulting reaction products are reacted with acetic acid and zinc to produce 4-(5-ethoxy-hept-1-yl)bicyclo[3.2.0]heptan-6-one and 4-(5-ethoxyhept-1-yl)bicyclo[3.2.0]heptan-7-one, which are reacted with trimethylsulfonium iodide to produce 2-(5-ethoxyhept-1-yl)spiro[bicyclo[3.2.0]heptane-6,2′-oxirane] and 4-(5-ethoxyhept-1-yl)spiro-[bicyclo[3.2.0]heptane-6,2′-oxirane]. Lithium iodide is reacted with 2-(5-ethoxyhept-1-yl)spiro[bicyclo[3.2.0]heptane-6,2′-oxirane] and 4-(5-ethoxyhept-1-yl)spiro-[bicyclo-[3.2.0]heptane-6,2′-oxirane] to produce 6-(5-ethoxyhept-1-yl)bicyclo[3.3.0]octan-3-one. A method of synthesizing 6-(5-methoxyhept-1-yl)bicyclo[3.3.0]octan-3-one is also described. | 01-21-2016 |
