Abstract:
Provided are a method for manufacturing a chlorogenic acid-containing composition, including a chlorogenic acid extraction step of obtaining a chlorogenic acid-containing liquid extract from sunflower seed residues remaining after oil expression by bringing chlorogenic acid and saccharides derived from the sunflower seed residues remaining after oil expression into contact with yeast and a solvent selected from the group consisting of water, an alcohol, and a liquid mixture of water and an alcohol, and a bacterial treatment step of performing at least one treatment selected from germicidal treatment or sterilization treatment on the liquid extract, a chlorogenic acid-containing composition obtained by the manufacturing method, and a drink or food item containing the chlorogenic acid-containing composition.
Abstract:
Provided is a polyamide polymer in which a partial structure represented by the following formula (C) constitutes a portion of the main chain: wherein in Formula (C), RA and RB each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; n and m each independently represent an integer from 0 to 2; Cy represents an unsaturated 6-membered or 7-membered ring which may contain a heteroatom; and * and ** each represent a bonding hand, while * may be a bonding hand extending from RA.
Abstract:
Provided are a method for manufacturing 3,4,5-tricaffeoylquinic acid, which can produce 3,4,5-tricaffeoylquinic acid with high efficiency by a simple operation in a short process using inexpensive raw materials, and intermediate compounds. The method for manufacturing 3,4,5-tricaffeoylquinic acid of the invention includes at least Step (1) of allowing a compound represented by Formula (1) or a compound represented by Formula (2) to react with a compound represented by Formula (4); and Step (2) of deprotecting the product obtained in Step (1), and producing 3,4,5-tricaffeoylquinic acid:
Abstract:
Provided is a polyester polymer including a repeating unit derived from a dicarboxylic acid compound containing a partial structure represented by the following Formula (C) and a repeating unit derived from a diol compound containing a cyclic structure, in which the partial structure represented by Formula (C) constitutes a portion of the main chain: wherein in Formula (C), RA and RB each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; n and in each independently represent an integer from 0 to 2; Cy represents an unsaturated 6-membered or 7-membered ring which may contain a heteroatom; and * and ** each represent a bonding hand, while * may be a bonding hand extending from RA.
