摘要:
The present invention provides lipase inhibitors containing dimers of flavan-3-ols derived from teas as well as foods and beverages and medicines containing said inhibitors. More specifically, the present invention provides lipase inhibitors containing at least one of assamicains represented by the formula: wherein G represents a galloyl group; theasinensins represented by the formula: wherein R1 represents G or H, and R2 represents G; and theaflavins represented by the formula:
摘要:
The present invention provides lipase inhibitors containing flavan-3-ol monomers or acylates thereof derived from teas as well as foods and beverages and medicines containing said inhibitors. More specifically, the present invention provides lipase inhibitors containing at least one of flavan-3-ol monomers represented by the formula: wherein R1 and R3 independently represent H or OH, R2 represents H, R4 represents H, G, 3MeG or p-cou, R5 represents H or G, R4′ and R5′ independently represent H or G, R4″ represents H or G, and G, 3MeG and p-cou respectively represent the groups of the formulae: or acylates thereof; as well as foods and beverages and medicines containing said lipase inhibitors.
摘要:
The present invention provides lipase inhibitory agents comprising a gallotannin or ellagitannin component(s) isolated from teas or Tellima grandiflora as well as foods and beverages and medicines containing said inhibitory agents. The present invention provides lipase inhibitory agents comprising at least one of compounds represented by formula I below: wherein R1, R2 and R3 independently represent H or a gallic acid residue, and R4 and R5 represent H or a gallic acid residue, or R4 and R5 together form an HHDP group represented by the formula below: provided that at least two of R1 to R5 represent a gallic acid residue or when all of R1, R2 and R3 are H, R4 and R5 together form the HHDP group; as well as foods and beverages and medicines containing said lipase inhibitory agents.

摘要:
This invention provides, a novel polyphenol compound having lipase inhibitory activity derived from tealeaves, a process for the preparation of the compound, and foods and/or beverages and pharmaceutical drugs containing the compound.Particularly, this invention provides a novel dimer compound of formula: obtained by oxidative polymerization of epigallocatechin-3-O-gallate, a main catechin component of oolong tea, with a tealeaf enzyme (polyphenol oxidase), as well as foods and/or beverages and pharmaceutical compositions containing said novel compound which suppress absorption of dietary lipids and suppresses increase of blood triglyceride.
摘要:
An object of the present invention is to provide a lipase activity inhibitor that shows high inhibitory activity against pancreatic lipase to suppress the absorption of meal-derived fat and/or which contributes to suppressing and preventing obesity, as well as a food or beverage that has such lipase activity inhibitor incorporated therein. Another object of the invention is to provide a lipase inhibitor of tea origin that suits most consumers' taste and which will not impair the flavor of the food or beverage when incorporated therein. Still another object of the invention is to provide a process for producing said lipase inhibitors. Further object of the invention is to provide antioxidants. To attain these objects, epigallocatechin dimers (oolong homobisflavans) or trimers are incorporated in foods or beverages. As a result, the absorption of meal-derived fat can be suppressed and, in addition, antioxidation effect is obtained. The compounds of the invention can be produced by reacting epigallocatechin gallate with formaldehyde in the presence of an acid.
