M. Miyazawa et al., BIOTRANSFORMATION OF (- AND (-)-LIMONENE BY THE LARVAE OF COMMON CUTWORM (SPODOPTERA-LITURA)()), Journal of agricultural and food chemistry, 46(1), 1998, pp. 300-303
(+)-Limonene was mixed in an artificial diet at a concentration of 1 m
g/g of diet, and the diet was fed to the last instar larvae of common
cutworm (Spodoptera litura). Metabolites were recovered from frass and
analyzed spectroscopically. (+)-Limonene was transformed mainly to ()-p-menth-1-ene-8,9-diol (uroterpenol) and (+)-p-mentha-1,8-dien-7-oic
acid (perillic acid). Similarly, (-)-limonene was transformed mainly
to (-)-p-menth-1-ene-8,9-diol (uroterpenol) and (-)-p-mentha-1,8-dien-
7-oic acid (perillic acid). The results indicate that there is little
difference in metabolic pathway between the (+)- and (-)-forms.
