    Abstract: 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.

  • Patent number: 7105719
    Abstract: The invention relates to isolated polynucleotides encoding a protein having aromatic acyltransferase activity, vectors comprising aromatic acyltransferase polynucleotides, and methods of transforming plants with anthocyanin acyltransferase polynucleotides to alter flower colors. The invention also relates to transformed host cells, plants, and flower cuts expressing proteins having anthocyanin acyltransferase activity.

  • Publication number: 20060174377
    Abstract: The present invention provides an enzyme which catalyzes a reaction to transfer sugar to a hydroxyl group at position 2? of chalcones and a gene thereof, and preferably an enzyme which catalyzes a reaction to transfer glucose to a hydroxyl group at position 2? of the chalcones. Furthermore, the invention provides a plant whose flower color has been changed using the glycosyltransferase. Using probes corresponding to conservative regions of the glycosyltransferase, some tens of glycosyltransferase genes having nucleotide sequences corresponding to the conservative regions were cloned from flower petal cDNA libraries of carnation and the like. Furthermore, each of the glycosyltransferase genes was expressed in Escherichia coli, activity to transfer glucose to position 2? of the chalcone, i.e., the glycosyltransferase activity at position 2? of chalcone was confirmed in an extract solution of the Escherichia coli, and it was confirmed that cloned genes encoded the glycosyltransferase at position 2?.

  • Publication number: 20060020123
    Abstract: The present invention provides a protein having aurone synthase activity involved in the color of flowers such as snapdragons, a gene that encodes it, cDNA in particular, and its applications. This gene can give yellow color to the flowers of plants by introducing into plants deficient in chalcone isomerase and so forth and expressing.

  • Patent number: 6770747
    Abstract: There is provided a gene encoding a protein derived from, for example, snapdragons and petunias, said protein having an amino acid sequence as set forth in SEQ ID NO: 2, 8, and 10, and having an activity of transferring a glycosyl group to aurones, and a method of producing said protein using said gene. By introducing this gene into plants that do not have said gene, a yellow pigment aurone can be stabilized and plants having yellow flowers can be obtained.

  • Publication number: 20030127351
    Abstract: There is developed a label which enables purchasers or ordinary consumers to identify suitable commodity products at a glance, thereby providing facilities for consumers when they purchase commodity products. A target user information label section corresponding to a target user of paper diapers packed in a package is printed at a position conspicuous for ordinary consumers on the surface of the package, along with a tradename of the paper diapers. All target user designs corresponding to all target users of paper diapers to be handled as commodities are displayed as a single set in the information label section. A specific target user design corresponding to a target user of the paper diapers packed in the package is displayed greater in size than the other target user designs belonging to the set.

  • Patent number: 5185283
    Abstract: This invention is to realize a final circuit by wiring only the top layer depending on the individual circuits, by fabricating a master slice in the step of up to forming plural semiconductor elements such as transistors on a semiconductor substrate, forming a lower layer of versatile wiring pieces thereon, and forming contact holes thereon. In this way, since the step just before formation of the top layer wiring can be carried out regardless of the features of individual circuits, preliminary mass productions are possible, and final products can be completed only by forming the wiring of the top layer depending on the requirements of the users. Accordingly, it is applicable to a wide variety of products, and the term for development and manufacture can be tremendously shortened.
