Accordingly, the lacquer tree extract of the present invention is safe to a user, and can be industrially used as a biofertilizer for improving antioxidant activity or growth to agricultural crops.
Abstract:
The present invention relates to a method for producing an ultrafine powder of cultured wild ginseng roots having reduced water absorption index (WAI) or swelling power (SW) and increased water solubility index (WSI) and particular ginsenoside content, wherein the method comprising a step of grinding cultured wild ginseng roots using a low-temperature ultrafine grinder; to an ultrafine powder of cultured wild ginseng roots having reduced water absorption index (WAI) or swelling power (SW) and increased water solubility index (WSI) and particular ginsenoside content; and to a food and a beverage containing the ultrafine powder of cultured wild ginseng roots. The ultrafine powder of cultured wild ginseng roots produced using a low-temperature grinder according to the present invention has a significantly reduced particle size, thereby changing the structure of the cultured wild ginseng roots and increasing the surface area thereof, and thus improving the texture feeling and increasing availability and absorptivity in the body. Therefore, processed products manufactured from the ultrafine powder of cultured wild ginseng roots allow active ingredients to be easily digested and absorbed into the body, contributing greatly to the health food industry using ginseng.

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.
