Abstract:
PURPOSE: COMT gene originated from Miscanthus sinensis and its use is provided to use for the yield increase controlling the anti oxidation activation of plants as the phenolic compound contents are controllable in the vector-transformed plant. CONSTITUTION: The method to control the phenolic compound content of plant comprises a step that controls the revelation of COMT gene by transforming recombinant vector in a plant cell which contains COMT [caffeic acid O-methyltransferase] gene originated from Miscanthus sineis; and a step that redifferentiates plants from the transformed plant cells. The phenolic compound content of plant is reduced by inhibiting the revelation of COMT gene. The phenolic compound contents of plant is increased by the overexpression of COMT gene. The phenolic compound of plant is flavonoid or lignine. The inhibition of COMT gene revelation is executed by transforming the plant with the recombinant plant vector in which COMT gene originated from Miscanthus sinensis is inserted in an anti-sense direction. The COMT gene is formed with a base rank of the rank number 1. The plant with reduced content of phenolic compound is produced by inhibiting the expression of COMT gene.

Abstract:
A whitening composition for external applications to the skin, containing kaempferol-3,7-o-alpha-l-dirhamnopyranoside is provided to suppress melanogenesis and to ensure excellent anti-freckles and skin whitening effect. A whitening composition for external applications to the skin comprises a kaempferol -3,7-O-alpha-L-di rhamnopyranoside as an active ingredient. The kaempferol-3,7-O- alpha-L-di rhamnopyranoside is derived from the kenaf. The kaempferol-3,7-O- alpha-L-di rhamnopyranoside is contained in an amount of 0.001~20.0 weight based on the total weight of the composition.
Abstract:
A kaempferol compound isolated from a kenaf extract(Hibiscus cannabinus) is provided to be used as active components of functional food with antibacterial and antioxidant activity. A functional food contains 0.1 to 20% by weight of a kaempferol compound represented by the formula(1) as an effective component from a kenaf extract and an excipient. The kaempferol compound is prepared by the steps of: obtaining crude extract by extracting kenaf leaf with methanol; obtaining a water layer and organic layer by extracting the crude extract with a solvent selected from water, aliphatic alcohol, aqueous alcohol solutions, hexane, chloroform, ethyl acetate, benzene and butanol; obtaining active fractions by absorbing the water layer and organic layer into a first silica chromatography column and eluting a fraction while changing the ratio of toluene and acetone or acetone and methanol; obtaining active fractions by absorbing the active fractions into a second silica chromatography column and eluting a fraction while changing the ratio of water and methanol(10:0 to 5:5); subjecting the fractions to gel filter chromatography(Sephadex LH-20) with 40% methanol; and finally recrystallizing the purified fractions and purifying a single active compound by high speed liquid chromatography.
