| Outline of Final Research Achievements |
Autoxidation of terpenoids, for example carophyllene, longifolene, thujopsene, and cembrene etc., was investigated to test the bio-activities of the reaction products. New autoxidation products were obtained from terpenoid autoxidation heated at 100-120 oC. Especially, as new knowledges for autoxidation mechanism, it was indicated that longifolene was converted into the autoxidation products via the formation of longifolene oxide as an intermediate. The bio-activities of the autoxidation products were tested on anti-termite anti-fungal, anti-algae activity and/or plant growth inhibitory activity. Most of autoxidation products had stronger activities for target organisms than original terpenoid before autoxidation. The bio-active products were obtained at a higher yield in the heating reaction than reaction at room temperature.
