ARALIA ELATA EXTRACT COMPOSITION HAVING ENHANCED ALCOHOL ABSORPTION INHIBITING ACTIVITY AND PRODUCTION THEREOF

摘要

PURPOSE: A method of preparing an Aralia elata(Miq.) Seem. extract composition by extracting Aralia elata(Miq.) Seem. and then subjecting the extract to hydrolysis treatment under basic conditions is provided. Thus obtained extract has excellent alcohol absorption inhibiting effect. CONSTITUTION: The leaf, sprout, bark or skin of Aralia elata(Miq.) Seem. is ground, dried and extracted. Thereafter, the extract is subjected to hydrolysis treatment in a heating and pressure device such as an autoclave and the hydrolysate is neutralized by acid treatment. For an example, 1kg Aralia elata(Miq.) Seem. powder is extracted in 20L water for about 6hr and concentrated to produce 2,000ml of an extract having a solid content of 10%. And 500ml of the extract is added with 0.1N NaOH, heated at 120deg.C for 30min and neutralized with 0.1N HCl.
