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.
