The results indicate that there is very close relation between E. exserta and E. leichow No. 1, and marked characteristic differences between E. citriodora oil and the oils of the former two species though they belong to one genus.

采用气相色谱与气-质联用法对广东产柠檬桉、窿缘桉和雷林1号桉叶精油进行定量和定性研究。确定出柠檬桉叶油29种化合物,窿缘桉和雷林1号桉叶油30多种化合物。色谱定量分别采用面积归一化法和13烷烃内标法,测得柠檬桉叶油含香草醛72.80%、香草醇14.51%;窿缘桉和雷林1号桉叶油含桉叶油素分别为35.69%和37.49%。从精油分析结果得知:窿缘桉酷似雷林1号桉,亲缘关系密切,而柠檬桉与它们虽同系桉树属,但性质差别甚大。

本文提出了一个简单、快速和直接的气相色谱法,用以测定食用油脂的氧化程度。采用液上气相色谱技术,样品气不经浓缩直接进样,以戊烷的相对生成量表示油脂的氧化程度。戊烷的定性,根据色谱——质谱联用的分析结果和色谱标准的戊烷的保留时间而定;戊烷的定量则采用面积归一法。比较了氧化产物,风味评分和过氧化值三者之间的关系。使用气相色谱法测得的氧化产物的结果与风味评分的结果比较,其相关系数 r=-0.8154。
