• 代謝

  H?m?l?inen (1912) claimed that menthone was probably oxidized in the rabbit to ketomenthone, since the glucuronide produced was converted by warm dilute H₂SO₄ to a substance which was probably △⁴⁽⁸ -p-menthen-3-one (pulegone). Williams (1940), however, showed that it underwent reduction in the rabbit with the production of d-neomenthol. The presence of l-menthol, the other possible reduction product, was not detected and it appeared that the biological reduction was asymmetric (Williams, 1959).
