Abstract:
PURPOSE: A meso-dihydroguaiaretic acid derivative, an inhibitor of the liver fibrosis containing the derivative, a Machilus thunbergii Sieb et Zucc. extract for inhibiting the liver fibrosis and a medical composition containing the extract for inhibiting the liver fibrosis are provided, wherein the derivative shows an excellent activity inhibiting the liver fibrosis. CONSTITUTION: The meso-dihydroguaiaretic acid derivative is represented by the formula 1, wherein R1 and R2 are independently H or an alkyl group of C1-C4; and R3 and R4 are independently an alkyl group of C1-C4 (but meso-dihydroguaiaretic acid is excluded). The Machilus thunbergii Sieb et Zucc. extract is obtained by extracting Machilus thunbergii Sieb et Zucc. with an alcohol of C1-C4, and optionally suspending it with water; fractionating the extracted one with CH2Cl2; and separating the obtained CH2Cl2 fraction by column chromatography.
