Patent number: 8318638Abstract: An object of the present invention is to determine novel means of activating plants; more particularly, means of controlling plant growth, such as means of promoting growth, means of controlling dormancy, means of imparting tolerance against stress for plants (dryness, high or low temperatures, osmotic pressure, etc.), and means of preventing aging. The present inventors have found that the above object can be achieved by providing plant activators containing, as an active ingredient, C4-C24 ketol fatty acids, in particular, 9-hydroxy-10-oxo-12(Z),15(Z)-octadecadienoic acid.Type: GrantFiled: December 6, 2010Date of Patent: November 27, 2012Assignee: Shiseido Company, Ltd.Inventors: Mineyuki Yokoyama, Shoko Yamaguchi, Toshii Iida, Kiyotaka Kojima, Koji Kobayashi, Osamu Tanaka

Patent number: 7749508Abstract: The present invention provides an antioxidant and a whitening agent having high safety, and a external preparation for skin using the same. The antioxidant and whitening agent comprise, as an effective component, one or more extracts from Basidiomycetes selected from the group consisting of Pleurotus abalonus, Pholiota squarrosa, Onnia orientalis, Astraeus hygrometricus and Pleurotus nebrodensis . These extracts have a free radical capturing ability and are useful for suppressing skin oxidation and for preventing and improving skin aging. In addition, the extracts have a tyrosinase activity inhibiting action and can suppress the melanin generation. Since the fruit bodies of these Basidiomycetes have been used for edible purpose and have high safety, they can be used preferably for an external preparation for skin.Type: GrantFiled: February 5, 2009Date of Patent: July 6, 2010Assignees: Shiseido Co., Ltd., Fumio EguchiInventors: Takeshi Nawamura, Nobuhiko Ochiai, Masato Hatao, Mineyuki Yokoyama, Koji Kobayashi, Fumio Eguchi
