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:
본 발명은 신품종인 밀양 263호를 비롯한 쌀, 쌀의 배 또는 이의 추출물을 포함하는 알코올 중독 예방 및 치료용 조성물에 관한 것이다. 본 발명이 제공하는 밀양 263호는 거대배 발달 유전자를 포함하는 흑찰거대배를 갖는 벼 식물체로, 기존 문제되었던 거대배 품종의 등숙 문제를 개선하였으며, 표면이 매끄러워 수확에 유리하며, 곡립에 안토시아닌 성분을 함유하고 있다. 특히 상기 밀양 263호를 비롯한 쌀은 기능성 성분에 의하여 알코올 중독의 예방 및 치료에 효과적이므로 약학 조성물이나 건강식품에 사용될 수 있어, 벼의 새로운 수요를 창출하고 쌀 산업의 경쟁력을 제고할 수 있다.
Abstract:
본 발명은 왕겨 및 쌀겨를 함유한 생분해성, 광분해성 바이오 필름 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 왕겨, 쌀겨, 전분, 이산화티탄 및 생분해성 폴리에스터를 포함하는 생분해성, 광분해성 바이오 필름 및 이의 제조방법에 관한 것이다. 본 발명의 생분해성, 광분해성 바이오 필름은 포장 작물의 생육환경에서 적합한 강도를 보유하며 생육기간이 끝나면 토양에서 분해되므로 포장 필름의 잔존에 따른 환경오염 문제를 방지하며, 포장 필름 수거비용 및 처리비용을 경감할 수 있다.
Abstract:
PURPOSE: A Vigna sp. extract having activity of suppressing alpha-glucosidase is provided to ensure blood glucose reductin, anti-obesity, and anti-oxidation. CONSTITUTION: A method for manufacturing Vigna sp. extract having an effect of suppressing alpha-glucosidase comprises: a step of pulverizing seed of Vigna; a step of adding 1-6 low alcohol or solution thereof and stirring at 20-30 °C to extract; a step of centrifuging extraction liquid to collect supernatant; and a step of performing decompression or freeze drying to obtain light brown and dark brown.
