Abstract:
A method for mass-propagating Oplopanax elatus Nakai plantlet is provided to establish the in vitro mass-production system of Oplopanax elatus Nakai, one of endangered plant species, thereby mass-producing the Oplopanax elatus Nakai which has useful pharmacological effects and is hard to be propagated. A method for mass-propagating Oplopanax elatus Nakai plantlet comprises the steps of: (a) germinating washed Oplopanax elatus Nakai seeds in an SH medium or a B5 medium at a temperature of 25 deg.C for 16 hours light condition and 8 hours dark condition; (b) culturing a fragment body of the germinated in vitro plant in a liquid medium or a solid medium to induce somatic embryos; (c) culturing the induced somatic embryos in a liquid medium or a solid medium to proliferate them; (d) culturing the proliferated somatic embryos in a liquid medium or a solid medium to redifferentiate a plantlet; and (e) acclimatizing the redifferentiated platelet in soil consisting of bed soil and sand in a mixture ratio of 1:1.

Abstract:
The present invention relates to a method for increasing biomass of ginseng adventitious roots, comprising a step of culturing the ginseng adventitious roots through light emitting diode (LED) irradiation at a red light wavelength range of 625-630 nm. The optimum proliferation conditions for culturing the ginseng adventitious roots through a bioreactor is developed by using the irradiation of the LED in a specific wavelength according to the present invention, thereby establishing the formation and growth of the favorable ginseng adventitious roots and the increase in biomass. Thus, provided can be a method for massively propagating the ginseng adventitious roots through tissue culture, capable of industrially mass-producing the ginseng adventitious roots in a bioreactor, thereby producing high value-added ginseng throughout the year without being affected by climatic and environmental conditions, and supplying the ginseng adventitious roots to various user classes at a low price.
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.

PURPOSE: A pharmaceutical composition containing Sorghum bicolor extract for preventing or treating cancer is provided to be used in a pharmaceutical composition or functional foods. CONSTITUTION: A pharmaceutical composition for preventing or treating cancer contains Sorghum bicolor extract as an active ingredient. The extract is an hexane fraction, ethyl acetate fraction, butanol fraction, or water fraction which is prepared by fractioning Sorghum bicolor crude extract with hexane, ethyl acetate, butanol, and water.
Abstract:
PURPOSE: Onion with the improved content of quercetin, and a producing method thereof are provided to radiate far infrared rays to dried onion for improving the content of the quercetin. CONSTITUTION: A producing method of onion with the improved content of quercetin comprises a step of radiating far infrared rays at 80deg C to dried onion for 20~30minutes. The onion is used to obtain an onion extract with the improved content of the quercetin by extracting the onion with a solvent. The onion extract is for producing functional food.
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.
