Abstract:
A composition comprising gallocatechin gallate(GCG) is provided to increase expression of cholesterol 7alpha-hydroxylase and expression of a low density lipoprotein receptor(LDLR) and show better binding increase efficacy between a low density lipoprotein(LDL) and the LDLR than that of epigallocatechin gallate(EGCG), thereby showing excellent hyperlipidemia improving effect. A composition for improving hyperlipidemia comprises GCG as an effective ingredient, active ingredient, wherein the GCG is derived from green tea. A food or a pharmaceutical formulation comprises the composition for improving hyperlipidemia. Further, the composition for improving hyperlipidemia reduces a number of tyighlycerides in blood and increases a high density lipoprotein.
Abstract:
A cosmetic composition is provided to inhibit the amount of sebum produced from sebocytes by inhibiting the formation and activity of SREBP-1(Sterol Regulatory Element Binding Protein-1), thereby capable of effectively improving sebum metabolism and acne. A cosmetic composition comprises 0.001-30 wt.% of at least one selected from the group consisting of catechin such as epigallocatechin gallate(EGCG), gallocatechin gallate(GCG) and a mixture thereof and flavonols such as quercetin, kaempferol and myricetin as effective ingredients and is characterized in that it inhibit the formation and activity of SREBP-1 which is a transcription factor.
Abstract:
A skin external composition is provided to inhibit TNF-alpha(Tumor Necrosis Factor-alpha) and the expression of MMP-1 through activation of PPAR-alpha(Peroxisome Proliferator Activated Receptor-alpha), thereby inhibiting skin aging. A skin external composition comprises 0.001-10 wt.% of at least one kind selected from the group consisting of epigallocatechin(EGCG), gallocatechingallate(GCG), epicatechin gallate(ECG), catechin gallate(CG), catechin(C), gallic acid, quercetin, kaempferol, theobromine, theophylline, theanine, quinic acid, an ethanol extract of green tea leaves, an aqueous extract of green tea leaves, an extract of catechin 1 including 70% of catechin and an extract of catechin 2 including 50% of EGCG as an effective ingredient.
Abstract:
A skin external composition comprising optimal concentration of catechins and theanine is provided to increase biosynthesis of collagen in the inner skin, restore elasticity of the skin, and improve wrinkles in the skin by containing low concentration of catechins and theanine at a fixed ingredient rate. The skin external composition for promoting biosynthesis of collagen and improving skin aging and elasticity comprises 0.0004-0.025 wt.% of catechins and 0.008-2.5 wt.% of theanine based on the total weight of the composition, wherein the weight ratio of catechins to theanine is 1:20 to 1:100, and the catechin is EGCG(epigallocatechin gallate), GCG(gallocatechin gallate), ECG(epicatechin gallate) or CG(catechin gallate).
Abstract:
PURPOSE: Provided is a composition for inhibiting phagocytosis containing Saururus Chinesis(Lour) Bail extract that effectively inhibits the phagocytosis of the keratinocyte activated by exposure to ultraviolet rays. Further, provided is a pharmaceutical composition which prevents and treats various kinds of diseases associated with phagocytosis. CONSTITUTION: A phagocytosis inhibiting composition is characterized by containing, as an active ingredient, Saururus Chinesis(Lour) Bail extract in the amount of 0.0001-10 wt.%. It is used for prevention and treatment of phagocytosis related diseases.
