| Research Abstract |
Reactions of autoxidation and direct-episulfidation were examined for sesquiterpene hydrocarbons which have unique ring structure. And bioactivities of products of the reaction were also tested for termite and wood decay fungi. Caryophyllene and humulene were easily changed to epoxides or episulfides by autoxidation or direct-epusulfidation. Longifolene and thujopsene were easily changed to unique products, norterpenoids or peroxides etc., by autoxidation. However, unique products were not produced in the reactions of longifolene or thujopsene with elemental sulfur. In the bioactivity tests, original sesquiterpene hydrocarbons had no bioactivities against the termite and the wood decay fungi. The autoxidation and direct-epusulfidation products had termicidal, anti-feedant and anti-fungal activities.
