Abstract

Urushiols are important active compounds found in the sap of the lacquer tree (Rhus verniciflua Stokes). Recently, various biological effects of urushiols, such as antioxidant, antimicrobial, and anticancer activities, have been reported. However, urushiols can also induce skin allergies. Nevertheless, the lacquer tree has traditionally been used in Korea as a folk medicine. In this study, we evaluated the absorption and metabolism of 3-pentadecylcatechol (PDC), a natural urushiol. PDC (48.0 mg/kg body wt.) in 1 mL propylene glycol was orally administered to rats (Sprague-Dawley, male, 6 weeks old). Blood plasma, urine, and feces were collected, separately. PDC was not detected in the extracts from rat blood plasma and urine. However, 89.4?±?5.2% of the orally administered PDC was detected in the feces extracts, indicating that PDC was predominantly excreted and not absorbed.
