广西肉桂栽培及精油成分

Cultivation of Cinnamomum cassia Pres and Analysis of its Essential Oil

中国肉桂原产我国 ,为一栽培种。本文对中国肉桂主产区广西的两大主产地 ,西江桂及防城桂作了大量的调查 ,包括桂皮采集、精油提取及成分分析。广西肉桂一般种植 4 -6年后即可开花结实 ,并可结合疏伐采收 ;8-1 0年生树即可剥取桂皮采收 ;1 0 -1 5年为理想采收期。不同种植地由于自然条件的影响 ,肉桂生育期有一定的差异。而不同品种、不同树龄、不同海拔肉桂油含量有明显的变化 ,但主成分肉桂醛含量变化较小。

Cinmamomum cassia Pres (Cassia bark tree), a cultivated variety, is originated from China. This study investigated Cassia tree growing in Xijang and Fangcheng counties, two major producing area of Guang Xi province in China; This investigation included bark collecting, extraction and analysis of esscntial oil. Usually cassia produces flower and fruit after growing 4-6 years, and can be barked after growing 8-10 years, but the optimal time is during 10-15 years. The bearing period of cassia has some differences because of different natural environment. The content of extracted oil has significant variation among different breed, tree age and altitude, however, the content of trans-Cinnamic aldehyde, the major component of extracted oil, shows little difference.
