Abstract:
PURPOSE: Provided are Aster scaber extract having anti-hyperlipemia, anti-oxidation and anti-virus activities and a novel compound separated therefrom. They are useful in manufacturing remedial compositions and food compositions which are used for the prevention and treatment of cardiovascular diseases caused by hyperlipemia and various diseases caused by oxidative stress. CONSTITUTION: The extract of Aster scaber is obtained by extracting Aster scaber with lower alcohol then drying the extract; and suspending the extract in water then adding an organic solvent thereto. The organic solvent is selected from the group consisting of methylene chloride, butanol, ethylacetate or their mixture. The novel compounds separated therefrom are as follows: (3S)-3,7-dimethyl-octa-1,5-diene-7-hydroperoxy-3-O-(3',4'-diangeloyl)-beta-D-glucopyranoside of the formula(1), (3S)-3,7-dimethyl-octa-1,7-diene-6-hydroperoxy-3-O-(3',4'-diangeloyl)-beta-D-glucopyranoside of the formula(2), methyl-3,5-dicaffeoyl-muco-quinic acid of the formula(3), (-) 3,5-dicaffeoyl-muco-quinic acid of the formula(4), and (-) 4-caffeoyl-muco-quinic acid of the formula(5).
Abstract:
A compound isolated from Aster scaber extracts is provided to ensure excellent hypocholesterolemic, antioxidative, and antiviral actions and be useful for preventing or treating cardiovascular diseases caused by hyperlipidemia and various diseases caused by oxidative stress. A compound isolated from Aster scaber extracts has a structure represented by the following formula 3, 4, or 5. In the formula 3, R is a methyl group, R1 and R3 are caffeoyl groups, and R2 is hydrogen. In the formula 4, R1 and R3 are caffeoyl groups and R2 is hydrogen. In the formula 5, R1 and R3 are hydrogen and R2 is a caffeoyl group. The Aster scaber extracts are obtained by extracting Aster scaber with lower alcohol, and extracting the obtained extract with an organic solvent again. The organic solvent is methanol, methylene chloride, ethylacetate, butanol, or a mixture thereof.
