摘要:
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 that Osteomeles sch werinae extract 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 said Osteomeles sch werinae extract and its fraction as an 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 of Hedera helix leaves and Coptis chinensis as 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 of Rheum palmatum , Puerariae radix, Ginkgo leaves, Cassiae semen , blueberry, bilberry, raspberry, or grape seeds as an active ingredient, in addition to the mixed extract of Hedera helix leaves and Coptis chinensis.
摘要:
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.
摘要:
Disclosed herein are a leaf and stem extract of Aster koraiensis, a root extract of Aster koraiensis, a flower extract of Aster koraiensis, a pharmaceutical composition for the prevention or treatment of diabetic complications, a health functional food for the improvement of diabetic complications, and a pharmaceutical composition and health functional food for the prevention or delay of aging, in which each of the compositions and the foods contain, as an active ingredient, at least one of said Aster koraiensis extracts. Each of the extracts is obtained by drying and finely cutting each of the leaf and stem part, root and flower of Aster koraiensis, extracting the cut plant with alcohol or aqueous alcohol solution, filtering the extracted solution and concentrating the filtrate under reduced pressure. Also disclosed are a pharmaceutical composition for the prevention or treatment of diabetic complications, a health functional food for the improvement of diabetic complications, and a pharmaceutical composition and health functional food for the prevention or delay of aging, which contain, as an active ingredient, at least one of fractions obtained by fractionating each of said Aster koraiensis extracts in the order of hexane, ethyl acetate, n-butanol and water fractions. The leaf and stem extract of Aster koraiensis, the root extract of Aster koraiensis and the flower extract of Aster koraiensis have the effect of inhibiting the production of advanced glycation endproducts (AGEs), the causes of diabetic complications, and effectively inhibit aldose redductase (AR) activity. Thus, the disclosed extracts will be highly useful for the prevention or treatment of diabetic complications and the prevention of aging.
