Patent number: 8603548Abstract: An anti-avian influenza virus agent containing, as an active ingredient, a component obtained when a guava extract extracted from a guava with an extraction solvent consisting primarily of at least one of water and a hydrophilic organic solvent is subjected to fractionation by HPLC under specific conditions. The specific conditions include the use of an ODS column, the use of a water-methanol mixture having a methanol concentration of 20% as a mobile phase during a period until 15 minutes after applying the guava extract to the column, and the use of a water-methanol mixture having a methanol concentration of 40% as a mobile phase during a subsequent period of 15 to 30 minutes. Alternatively, the specific conditions further include the use of a water-methanol mixture having a methanol concentration of 60% as a mobile phase during a period of 30 to 45 minutes after applying the guava extract to the column.Type: GrantFiled: October 8, 2009Date of Patent: December 10, 2013Assignee: Pokka CorporationInventors: Syuichi Fukumoto, Kenji Kumagai, Yasuo Suzuki, Nongluk Sriwilaijaroen

Patent number: 8247002Abstract: An antioxidant material of the present invention contains flavonoid aglycon and vitamin C. The flavonoid aglycon is eriodictyol and/or diosmetin obtained by treatment of a raw material containing flavonoid glycoside derived from lemons, limes, or sudachis to form the aglycones thereof. It is preferred that this antioxidant material be produced through a step of mixing the flavonoid aglycon and the vitamin C after the treatment to form the aglycones. The treatment to form the aglycones is glycosidase treatment using a ?-glycosidase derived from a microorganism of the genus Aspergillus or Penicillium multicolor, or microbial fermentative treatment using a microorganism of the genus Aspergillus. An anti-deterioration agent and a food or beverage of the present invention contain the antioxidant material.Type: GrantFiled: February 27, 2009Date of Patent: August 21, 2012Assignees: Pokka Corporation, Amano Enzyme Inc.Inventors: Syuichi Fukumoto, Kazutaka Tsuruhami, Shigeharu Mori
