Abstract:
PURPOSE: An antibacterial or antivirus composition containing a rice aerial part extract or a flavonolignans compound separated from the extract is provided to prevent influenza virus. CONSTITUTION: Salcolin represented by chemical formula 1, salcolinoside A represented by chemical formula 2, salcolinoside B represented by chemical formula 3, salcolinoside C represented by chemical formula 4, or a pharmaceutically acceptable salt thereof is prepared. An antibacterial or antivirus pharmaceutical composition comprises one or more selected from a group including the salcolin, the salcolinoside A, the salcolinoside B, the salcolinoside C, and the pharmaceutically acceptable salt thereof as an active component. The pharmaceutical composition is useful as a medicine for preventing and treating influenza virus. A food addition of preventing and overcoming a disease infected by bacteria or virus comprises a rice aerial part extract or a fraction thereof. A feed addition of preventing and overcoming a disease infected by bacteria or virus comprises a rice aerial part extract or a fraction thereof.
Abstract:
PURPOSE: A cosmetic composition containing an Echinochloa utilis extract, and a compound isolated from the same are provided to suppress tyrosinase activity and melanogenesis by reducing expression of TRP-1 and TRP-2. CONSTITUTION: A cosmetic composition for skin whitening contains an Echinochloa utilis extract as an active ingredient, and suppresses tyrosinase activity. The active ingredient includes one or more among compounds of chemical formulas 1-5. A method for preparing the extract comprises: a step of drying Echinochloa utilis and pulverizing; a step of extracting the Echinochloa utilis with C1-C4 alcohol; a step of adding water and suspending; a step of adding an organic solvent, and preparing each fraction; and a step of eluting the fraction on a silicagel column.
Abstract:
PURPOSE: A composition containing a DNA marker for selecting Oryza sativa with green rice leaf hopper-resistant gene Grh1 is provided to efficiently distinguish green rice leaf hopper resistant and sensitive individual. CONSTITUTION: A composition for selecting Oryza sativa species with green rice leaf hopper-resistance contains a primer for detecting the presence of an oligonucleotide or a fragment thereof. The primer is one or more primer sets selected from sequence numbers 1-14. The primer set is one or more primer sets selected from sequence numbers 3-14. A method for selecting the Oryza sativa species comprises: a step of isolating genome DNA from Oryza sativa samples; a step of amplifying a target sequence using the genome DNA as a template and the primer set; and a step of detecting the amplifies product. The sample is derived from roots, leaves, stems, flowers, or buds of Oryza sativa. A kit for selecting Oryza sativa species with green rice leaf hopper-resistance contains the primer set selected from sequence numbers 1-14, restriction enzyme, and reagent.
