摘要

本試驗進行台東東河及嘉義兩農場人工栽培土肉桂葉精油之收率測定及成分分析。經過一年之觀察，瞭解培育之土肉桂無論葉精油收率或成分含量均具有地區性和季節性之變化。一年中，精油收率最高之時期為7月至9月。主成分桂皮醛之平均百分比達70%以上，但是，不同營養系及不同栽植地樣品中桂皮醛含量時序變化則並不十分一致。其他平均百分比高於1%之成分包括苯甲醛，4-丙烯苯甲醚，乙酸香葉酯及乙酸桂皮酯等。比較台東及嘉義兩栽培地區於相同月份收集之同號營養系土肉桂，得知前者之平均精油收率及桂皮醛含量均高於後者。

The leaf samples of cultivated Cinnamomum osmophloeum Kaneh. were collected from Tai-tong and Chiayi farms, respectively. Their essential oils were extracted and analyzed. through one-year's examinations, both yields and compositions of essential oils had been found to vary with the cultivating locations and growing seasons. From July through September, the yields of essential oils were at their maxima. The average percentage of cinnamaldehyde was determined to be more than 70% in most samples. However, this composition's seasonal variations for samples from different clones and planting locations were not quite consistent with each other. Other major compositions included benzaldehyde, 4-allylanisole, geranyl acetate, and cinnamyl acetate. Besides, either the yield of essential oil or the percentage of cinnamaldehyde from Tai-tong's leaf sample was observed to be higher than that from Chia-yi's sample from the same clone, collected in the same month.
