项目摘要

Chemical conversion of major components of wood essential oil into biological-resistant compounds, especially termiticidal and anti-fungal compounds by relatively simple reaction was carried out. α-Pinene, widely contained in the wood essential oil was converted with a dilute sulfuric acid solution into α-terpineol, one of the termiticidal compounds, on yield of ca. 22 molar %. Furthermore, some sulfonic acids were found to be a good catalyst for these reactions. p-Phenol sulfonic acid was the best catalyst among them, it gave maximum yield α-terpineol, 83 molar %. The essential oil from matu, sugi, and hinoki woods were also treated with p-phenol sulfonic acid. α-Pinene contained in matu essential oil was converted into α-terpineol. But, commercial terpentine and sugi essential oil contained less α-pinene, so the production of α-terpineol was a little. The hinoki leaf oil contained a lot of sabinene instead of α-pinene which was converted into 4-terpineol by these treatments. Adequate reaction time was less than 10 hrs and longer reaction time increased the unfavorable products. The reaction products were tested for the termiticidal activity against Coptotermes formosanus and Reticulitermes speratus, the fungus resistance against five fungi specified in JIS Z 2911. Although the hydrolysis product, e.g. from sugi essential oil, having less amount of terpene alcohols showed only a little increase of biological activity, the products from hinoki and matu essential oil showed remarkable increase of it.

通过相对简单的反应，将木精油的主要成分化学转化为生物抗性化合物，特别是杀白蚁和抗真菌化合物。广泛存在于木精油中的α-蒎烯用稀硫酸溶液转化为α-萜品醇，一种杀白蚁化合物，产率约为。 22摩尔％。此外，一些磺酸被发现是这些反应的良好催化剂。其中对苯酚磺酸是最好的催化剂，它得到最大的α-萜品醇产率，83摩尔%。来自马图、杉木和扁柏的精油也经过对苯酚磺酸处理。马图精油中所含的α-蒎烯转化为α-萜品醇。但市售的松油和杉精油中α-蒎烯含量较少，因此α-松油醇的产量也很少。扁柏叶油中含有大量的桧烯而不是α-蒎烯，通过这些处理将α-蒎烯转化为4-萜品醇。充足的反应时间少于10小时，较长的反应时间增加了不利的产物。测试反应产物对台湾乳白蚁和散白蚁的杀白蚁活性，以及对JIS Z 2911中规定的五种真菌的抗真菌性。杉精油中萜醇含量较少，生物活性仅略有增加，而扁柏和马图精油产品的生物活性则显着增加。
