- Biotransformation of (+)- and (-)-menthol by the larvae of common cutworm (Spodoptera litura)
-
(+)-Menthol was mixed in an artificial diet at a concentration of 1 mg/g of diet, and the diet was fed to the last instar larvae of common cutworm (Spodoptera litura). Metabolites were recovered from grass and analyzed spectroscopically. (+)-Menthol was transformed mainly to (+)-7- hydroxymenthol. Similarly, (-)-menthol was transformed mainly to (-)-7- hydroxymenthol. The C-7 position of (+)and (-)-menthol was preferentially oxidized.

- Fungal transformation of (1R,2S,5R)-(-)-menthol by Cephalosporium aphidicola
-
Incubation of (1R,2S,5R)-(-)-menthol (1) with Cephalosporium aphidicola for 12 days yielded the six oxidized metabolites: 10-acetoxymenthol (2), 7- hydroxymenthol (3), 4α-hydroxymenthol (4), 3α-hydroxymenthol (5), 9- hydroxymenthol (6), and 10-hydroxymenthol (7). The structures of the novel compounds 2, 4, 5, and 7 were assigned by interpretation of their spectral data.
