Abstract:
The present invention relates to an extract of processed Panax genus plant obtained by maillard browning reaction of Panax genus extract with at least one amino acid selected from the group consisting of valine, arginine, and alanine at 100-130°C for 0.5-12 hours; a method for manufacturing the same; and a composition comprising the extract for anti-cancer, neuroprotection, inhibition of platelet aggregation, antioxidant, anti-inflammatory, renal protection, or anti-fatigue. The present invention also provides an extract of processed Panax genus plant obtained by maillard browning reaction of Panax genus extrac with at least one amino acid selected from the group consisting of leucine and glutamine at 100-130°C for 0.1-12 hours; a method for manufacturing the same; and an anti-cancer composition comprising the extract.
Abstract:
The present invention provides a composition having antiviral activities which include neorhodomela extracts as an active ingredient. In addition, the present invention provides a method for isolating polybromocatechol which comprises the steps of: obtaining the extract by extracting the neorhodomela using organic solvents and vacuum distilling the same; obtaining fraction extracts by fractioning the organic solvent extracts obtained from the previous step using polar difference of solvents; and isolating and purifying the fraction extract obtained from the previous step using chromatography. According to the present invention, the antiviral substances can be provided which is safe, have enhanced inhibition ability for human rhino virus, and has low toxicity by being derived from a natural product. In addition, the polybromocatechol compound can easily be isolated from the neorhodomela so that the present invention can provide a pharmaceutical composition which can be used for preventing and treating viral diseases.

Abstract:
PURPOSE: A Panax species plant extract having the increased content of ginsenoside Rg5 and Rk1 by microwave irradiation, a manufacturing method thereof, and a composition containing the processed Panax species plant extract are provided to enhance an effect of Rg5 and Rk1 compared to an extract by simple thermal-processing. CONSTITUTION: A manufacturing method of a Panax species plant extract comprises: a step of irradiating Panax species plants or an extract thereof with microwaves. The Panax species plant or the extract contains more than 90% of Rg3, Rk1, and Rg5 to the weight of ginsenoside Rb1, Rc, Rb2, Rd, Rg3, Rk1 and Rg5. The microwave irradiation is performed at 150-190 deg. C for 30-90 minutes while pressurizing. The microwave irradiation is performed under 2-100 atmospheric pressure. The Panax species plant extract has a ratio of ginsenoside (Rg5+Rk1)/(Rg3) of 2 or greater. [Reference numerals] (AA) Voltage(mv); (BB) Time(minutes)
