摘要：
Crystal-clear peppermint oil maintaining its noble character and having a reduced pulegone content, enhanced menthone and menthol content, and improved stability against menthofuran oxidation breakdown is produced by a stereospecific method of reduction by hydrogenation of pulegone in situ using a saturated aqueous solution of sodium sulfite in the presence of glacial acetic acid at approximately neutral pH.
