In view of this phenomenon, the camphor crystals and the oil layer were separated preliminarily by vacuum filtration and their chemical composi- tions were analyzed qualitatively and quantitatively by GC-MS and GC. The results showed that the vacuum filtration was one of the ways for purifying the camphor oil of camphor type. After the es- sential oil was separated, the content of camphor reached to 94.671%. In the oil layer, the content of single terpenoids and half the terpenoids substances is 88.597% and 10.554% respectively, and the contents of camphor (50.864%), D-limonene (12.490%), alpha pinene (3.458%), beta myrcene (4.199%), 4-terpineol (2.260%), alpha terpineol (3.915%), caryophyllene (3.973%) and humu- lene (3.036%) are more than 2%. These main chemical compositions can be used by fractionation. Keywords Oil of Camphor Tree Leaves, Camphor 樟脑型樟叶油成分分析 李桂珍，梁忠云，蔡 玲，陈海燕 广西壮族自治区林业科学研究院，广西 南宁 文章
