    摘要: PROBLEM TO BE SOLVED: To provide an effective and low-cost method capable of preparing high-purity hydroxytyrosol easily.SOLUTION: There is provided a method for preparing hydroxytyrosol in which a compound of the formula (1) (X is CHOH or CHOM(M=Li, Na, K, Mg, Ca); Ror Ris represented by a methyl group) and an aluminum compound of the formula (2) AlRRR(2) (R, Rand Rare H or an alkyl group having 1 to 8 carbon atoms) are reacted and then an aqueous solution of hydroxy carboxylic acid is added in an amount so that a transparent, homogeneous acidic solution having a pH of 3 or less is formed, followed by extracting hydroxytyrosol from the aqueous, homogeneous acidic solution to remove an organic solvent.
