Abstract: An object of the present invention is to provide tea leaf powder from which the liquid extracted has a favorable liquid color. That is, the present invention provides a tea leaf powder having 300 ?m or more of 50% particle diameter measured by a laser diffraction type particle size distribution measuring apparatus on volume basis, and 0.05% by weight or more of anthocyanin content. The tea leaf powder preferably has 120 ?m or more of 10% particle diameter measured by a laser diffraction type particle size distribution measuring apparatus on volume basis.

Abstract: An object is to find out a safe component that can effectively exhibit action including the protection of a brain function, the prevention or alleviation of a reduction in cognitive ability, and the prevention or alleviation of dementia. A component of a plant body of a hybrid between Camellia sinensis and Camellia taliensis is contained as an active component. The hybrid between Camellia sinensis and Camellia taliensis is preferably Sunrouge. A tea leaf extract of the plant body of the hybrid between Camellia sinensis and Camellia taliensis is preferably contained.

Abstract: An object of the present invention is to find a component that is safe and is capable of effectively exerting various effects such as prevention or amelioration of diabetes, prevention or amelioration of metabolic syndrome, amelioration of insulin resistance, inhibition of an increase in a postprandial blood sugar level, and inhibition of ?-glucosidase activity. The present invention provides agents for preventing or ameliorating diabetes or the like, the agents including a component of a hybrid plant of Camellia sinensis and Camellia taliensis as an active ingredient. The hybrid plant is preferably Sun Rouge, and each of the agents preferably includes a tea leaf extract of the hybrid plant.

Abstract: The present invention provides a method for cultivation of a genetically-modified plant that can highly produce a desired protein. More specifically, the present invention provides a method for cultivation of a genetically-modified plant comprising: cultivating the genetically-modified plant in a medium, wherein the genetically-modified plant is transformed by introducing an expression vector comprising a promoter regulating expression of RNA and a seed storage protein isolated from a plant that highly expresses RNA and the seed storage protein under a high nitrogen condition; and a polynucleotide encoding an objective protein, and wherein the medium is adjusted so that nitrate nitrogen is 70 mg/L to 750 mg/L and/or ammonium nitrogen is 70 mg/L to 750 mg/L for a definite period in a period from 30 days before an expected flowering date to a date on or before flowering of the genetically-modified plant.
