摘要

本試驗選取5種化學品系的土肉桂（Cinnamomum osmophloeum）、錫蘭肉桂（Cinnamomum zeylanicum）、山肉桂（Cinnamomum insularimontanum）、陰香（Cinnamomum burmani）等樟屬植物葉精油及其主要成分，對Aspergillus niger, A. terreus, Chaetomium globosum, Penicillium citrinum, Trichoderma viride 5株黴菌進行防黴性的篩選，然後將道林紙以防黴效果較佳的精油及成分分別予以浸漬處理，再進行不同劣化試驗，並評估紙張的性質變化。試驗結果得知，土肉桂精油（桂皮醛型及桂皮醛－桂皮乙酸酯型）及精油成分Cinnamaldehyde 對5株黴菌有良好的抑制效果，Cinnamaldehyde的防黴效果甚至比常用的防黴燻蒸劑瑞香酚佳。另外，道林紙經2％桂皮醛型土肉桂精油及2％桂皮醛之乙醇溶液浸漬後的防黴紙能完全抑制5株黴菌的生長，且經2％桂皮醛型土肉桂精油及2％桂皮醛浸漬的道林紙經放置室內16星期、加速老化試驗288 hr後，並不會影響道林紙之顏色與pH值，但紙張的抗張指數及耐摺強度在浸漬處理後較弱。

In this study the anti-mildew properties of papers treated with eight plant leaf essential oils-five chemo-types of Cinnamomum osmophloeum, Cinnamomum zeylanicum, Cinnamomum insularimontanum and Cinnamomum burmani and their main components were evaluated by anti-mildew assay. The essential oils and their main components with anti-mildew activities were further used for the paper dipping treatments. The paper properties were examined by using indoor exposure test, accelerated aging test, and artificially accelerated lightfastness test. Results revealed that C. osmophloeum leaf oil of cinnamaldehyde type and cinnamaldehyde -cinnamyl acetate type and their main constituent, cinnamaldehyde, had great inhibitory effects on the growth of Aspergillus niger, Aspergillus terreus, Chaetomium globosum, Penicillium citrinum, and Trichoderma viride. Cinnamaldehyde had the best inhibitory effects and even better than that of the popular fumigant, thymol. In addition, anti-mildew papers using wood free paper were treated with 2% ethanol solutions of cinnamaldehyde type of C. osmophloeum leaf oil and cinnamaldehyde, respectively. They inhibited completely the growth of five mildews tested, and no significant difference in the color variations and the pH value were observed compared with those of the untreated papers after indoor exposure for 16 weeks and accelerated aging test for 288 hr. However, the changes of tensile index and folding endurance of wood free paper after the treatments with 2% cinnamaldehyde type of C. osmophloeum leaf oil and 2% cinnamaldehyde were comparatively lower than the untreated paper.
