摘要

本研究之主要目的在分析本省各地千年桐，三年桐果實之組成及桐油之理化性質，試驗結果歸納如下：千年桐果實每顆重量：17.311~23.88g，種子重量：2.43~3.47g；含良好種仁百分率：62.50~90.41%；乾種仁含油率：54.88~59.30%；種子含油率：21.78~33.07 %；碘價介於157~160之間，膠化時間約12分鐘，果實性質以惠蓀林場產者最優良。三年桐果實平均重量：16.77g；種子平均重量：2.09g；含良好種仁百分率：61.9%；乾種仁含油率：58.91%：種子含油率：28.87%；碘價162，膠化時間10分鐘。

In this study, the composition of the fruit and chemical-physical constants of the tung oil of wood oil tree (Aleurites montana wils.) and tung oil tree (Aleurites fordii Hemsl.) growing in various parts of Taiwan were analyzed. The results drawn from these studies are summarized as follows: In Taiwan, the composition of the fruit and chemical-physical constants of wood oil tree were shown as follows: fruit and seed weight: 17.31 to 23.88 g/per fruit, 2.43 to 3.47 g/per seed; percentage of good kernels: 62.50 to 90.41 %; oil contain: 54.88 to 59.30% in dried kernels, 21.78 to 33.07% in the seeds; Iodine value: 157 to 160, gel time: about twelve minutes. The best characteristics of fruit was-produced from Hue-sun experimental Forest, National Chung-hsing University. As for tung oil tree, there were; fruit and seed weight: 16.77 g/per fruit, 2.09 g/per seed; percentage of good kernels: 61.9%; oil contain: 58.91% in dried kernels, 28.87% in the seeds; Iodine value: 162, gel time: ten minutes.
