Anethofuran, Carvone, and Limonene: Potential Cancer Chemoprotective Agents from Dill Weed Oil and Caraway Oil

Bioassay-directed fractionation of dill weed oil and caraway oil, respectively, from the plants Anethum graveolens L. and Carum carvi L. (Umbelliferae) has led to the isolation of three monoterpenes, anethofuran (1), carvone (2), and limonene (3). Their structures were determined on the basis of spectral analysis. These compounds induced the detoxifying enzyme glutathione S-transferase in several mouse target tissues. The alpha,beta-unsaturated...
