The extract of a mixture of cinnamon twig and moutan root bark, cinnamon twig and peony root, or cinnamon twig and poria according to the present invention has been confirmed to inhibit the excessive generation of advanced glycation end-products, which occurs under chronic diabetic conditions, exhibit the effect of fragmentizing a cross-link between the advanced glycation end-products and matrix proteins, have an excellent effect in inhibiting the generation of the advanced glycation end-products in a human retinal pigment epithelial cell line subjected to a hyperglycemic or aging environment, and have excellent effects in delaying, preventing, and treating diabetic complications, muscular degeneration, commotio retinae, and lower extremity edema in various animal models of diabetic complications, macular degeneration, and lower extremity edema, and thus the mixture extract can effectively be used as an active ingredient for a composition for preventing and treating diabetic complications, including diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy, and angioedema, including macular (retinal) edema, macular degeneration, and varicose veins.

Pharmaceutical composition for preventing or treating diabetic complications and angioedema, containing natural mixture extract as active ingredient

The present invention relates to a pharmaceutical composition for preventing or treating angioedema, containing as an active ingredient a peony root extract or an extract of a mixture of peony root and licorice. In particular, the extract of a mixture of peony root and licorice according to the present invention inhibits the excessive generation of advanced glycation end products, which may cause macular degeneration, inhibits blood-retinal barrier breakdown causing retinal edema in various animal models, protects or treats a subretinal region causing dry macular degeneration, inhibits angiogenesis causing wet macular degeneration, and thus can be usefully used as an active ingredient for the composition for preventing and treating angioedema including macular degeneration, macular edema, retinal edema, or varicose veins.

Pharmaceutical composition for preventing or treating angioedema, containing extract of peony root or mixture of peony root and licorice as active ingredient

The present invention relates to a pharmaceutical composition and a health functional food composition for prevention, treatment or amelioration of diabetic complications or angioedema containing a mixed extract ofleaves andas an active ingredient. More specifically, the present invention relates to a pharmaceutical composition and a health functional food composition for prevention, treatment or amelioration of diabetic complications or angioedema further containing an extract ofleaves,, blueberry, bilberry, raspberry, or grape seeds as an active ingredient, in addition to the mixed extract ofleaves and

Pharmaceutical composition and functional food comprising natural extracts for preventing or treating diabetic complications or angiodema

The present invention relates to the obesity-curative or obesity-preventive effect of abutanol fraction and aethylacetate fraction, and more particularly, to a pharmaceutical composition and a functional food for treating obesity, the pharmaceutical composition and the functional food comprising abutanol fraction (POCU-1b) and an ethylacetate fraction as active ingredients, wherein thebutanol fraction and the ethylacetate fraction inhibit effectively the activity of pancreatic lipase, an important enzyme involving in fat absorption in a living body, and have excellent inhibitory effect on fat absorption in the short term fat absorption-inhibitory animal experiments using lipid emulsions.

Compositions and functional foods for treating and preventing obesity using polygonum cuspidatum butanol fraction and ethyl acetate fraction

The present invention relates to a pharmaceutical composition for the prevention and treatment of diabetic complications comprising the extract ofLour. or the fraction thereof as an active ingredient. More particularly, the extract ofLour. or the fractions thereof of the present invention can inhibit the activity of aldose reductase and the generation of the advanced glycation endproducts, the index of diabetic complications, and have powerful activity of inhibiting diabetic complications with brining the anti-cataract, anti-retinopathy, and anti-neuropathy effect, and have the activity of anti-oxidation as well, so that they can be effectively used as an active ingredient of a pharmaceutical composition for the prevention and treatment of diabetic complications.

Pharmaceutical composition for preventing and treating complications of diabetes containing a traditional oriental medicine extract or a fraction thereof as an active ingredient

The present invention provides a novel biphenyl compound or pharmaceutically acceptable salts thereof, methods for preparing the same, and pharmaceutical compositions for preventing or treating diabetic complications containing the same as an active ingredient. Novel biphenyl compounds, according to the present invention, effectively suppress generation activity of advanced glycation end products, which cause diabetic complications and are a criterion for evaluating the effectiveness of a treating agent for diabetic complications, and show an excellent therapeutic effect on retina blood vessels, increased occludin, and decreased angiogenic growth factor in actual diabetic retinopathy induced retina. Thus, novel biphenyl compounds according to the present invention can be used effectively as an active ingredient in compositions for preventing or treating diabetic complications such as diabetic retinopathy.

Biphenyl compound or pharmaceutically acceptable salt thereof, method for preparing novel biphenyl compound or pharmaceutically acceptable salt thereof, and pharmaceutical composition containing same as active ingredient for preventing or treating diabetes complications

The present invention relates to a treatment agent for diabetic complications, and a method for the treatment of diabetic complications using the same. The present invention confirmed thatextract and its fractions inhibited the generation of AGEs, the index for diabetic complications, inhibited the activation of aldose reductase, had anti-cataract activity, and had anti-oxidative activity. Thus, the present invention relates to a preventive and therapeutic agent for diabetic complications containing the saidextract and its fraction as an active ingredient.
