Abstract:
A composition comprising the extract, a fraction or an isolated compound of Thuja orientalis is provided to inhibit sorbitol accumulation and non-enzymatic saccharification causing neurological disorder and neurological damage by inhibiting aldose reductase, so that the composition is useful for prevention or treatment of diabetic complications. A composition for prevention or treatment of diabetic complications comprises the extract, a fraction or an isolated compound of Thuja orientalis such as quercitrin which is isolated by (1) extracting Thuja orientalis with water, C1-C4 lower alcohol or a mixture thereof, (2) fractionating the extract of Thuja orientalis with ethyl acetate, and (3) adding CH2Cl2-MeOH or hexane-ethylacetate into the fraction of Thuja orientalis, and is a pharmaceutical or health food composition.

Abstract:
PURPOSE: An anti-inflammatory composition containing Desmarestia viridis extract is provided to suppress the expression of iNOS and interleukin-1B without cytotoxicity. CONSTITUTION: An anti-inflammatory pharmaceutical composition contains 0.001~99.9 weight% of Desmarestia viridis extract as an active ingredient. The Desmarestia viridis extract is isolated using water, low alcohol of C1-C4, or their mixture solvent. The low alcohol is methanol or ethanol. A health functional food composition for preventing or relieving inflammation contains the Desmarestia viridis extract as an active ingredient. The daily dose of the Desmarestia viridis extract is 0.1-500 mg/kg.
Abstract:
An agent for preventing and treating diabetes complication, and a health food are provided to inhibit the activity of the final sugar product and the aldose reductase. An agent for preventing and treating diabetes complication contains an extract of a lacquer tree (Rhus verniciflua) obtained by using water, an alcohol or their mixture as a solvent. Preferably the agent contains further an organic solvent fraction extracted by using an organic solvent. Preferably the organic solvent is n-hexane, methylene chloride, ethyl acetate or n-butanol.
Abstract:
A method for extraction of tectoridin and tectorigenin from the rhizomes of Belamcanda chinensis is provided to reduce the extraction time, improve the extraction yield and enhance environment and human affinity by using only water and ethanol as solvent under high temperature and high pressure. The tectoridin and tectorigenin are extracted from the rhizomes of Belamcanda chinensis through SWE(subcritical water extraction) by heating the rhizomes of Belamcanda chinensis in a mixed solvent containing water and 30-100 vol.% of ethanol to high temperature such as 80 deg. C or more, preferably 80-200 deg. C under high pressure condition such as 1-15 MPa.
Abstract:
A composition comprising an extract of Phyllostachys nigra MUNRO, a fraction thereof or a compound isolated from the fraction is provided to inhibit accumulation of sorbitol, a fundamental cause of nephropathy and neuropathy shown as diabetic complications, by inhibiting aldose reductase, thereby being used as a pharmaceutical composition or a health food for preventing diseases related to the diabetic complications. A method for isolating a compound from Phyllostachys nigra MUNRO comprises the steps of: (a) extracting the Phyllostachys nigra MUNRO with ethanol and filtering the extract; (b) concentrating and freeze-drying the filtrate to obtain an extract; (c) fractionating an ethylacetate layer from the extract using a separation funnel; and (d) subjecting the fraction to silica gel column chromatography using CH2Cl2-MeOH as a solvent to obtain orientin, luteolin 6-C-(6''-O-transcaffeoylglucoside), tricetin 3',4',5'-trimethyl ether 7-O-b-D-glucopyranoside, tricine, p-coumaric acid or cis-coumaric acid. A pharmaceutical composition for preventing or treating diabetic retinopathy, diabetic neuropathy or diabetic nephropathy comprises the obtained compound as an effective ingredient.
