WebThe proportions of isomenthyl propionate, neomenthyl propionate, menthyl propionate, and isoneomenthyl propionate were 10, 38, 50, and 2%, respectively in the menthyl propionate substrate mixture. The four constituents were all racemic (ees = 0). Hydrolysis was performed in 2 mL screw-capped tubes containing 1,880µL enzyme solution, WebAcid hydrolysis of the nonvolatile material released over half of the radioactivity to the steamvolatile fraction, and the major component of this fraction was identified as (+)-neomenthol by radiochromatographic analysis and by synthesis of crystalline derivatives, thus suggesting the presence of a neomenthyl glycoside.
WebThe neomenthol, however, is largely converted to neomenthyl-β-d-glucoside (80) which is transported from the leaf to the rhizome where the glycoside is rapidly hydrolyzed. The aglycone is then oxidized back to menthone which undergoes an unusual lactonization reaction to form 3,4-menthone lactone ... WebGeneral description.
