| Outline of Final Research Achievements |
The applications of needle essential oils are limited due to the easy degradation by ambient factors such as heat, UV rays and air; however, these factors can be regarded as valuable properties. The aim of this study is to discover high added-value of domestic needle oils by utilizing volatility and oxidation properties. In this study, following topics: 1) effective treatments by utilizing volatility and oxidation properties; 2) biological activities of treated oils; 3) usable forest materials containing high-reactive components, were investigated.
The needle oils of Pinus thunbergii, Cryptomeria japonica and Thujopsis dolabrata var. hondae were used for the mild heat and UV-A treatments. The major achievements were as follows: 1) mild heat treatments enhanced antifungal activities of essential oils; 2) some p-menthadiene components selectively changed by UV-A irradiation; 3) Abies sachalinensis bark was found as a usable material for extracting β-phellandrene-rich essential oil.
