对上海地区引种栽培的一年生和三年生的鼠尾草植物不同季节(夏季-8月,秋季-10月,冬季-1月,春季-4月)的叶子,用水蒸气蒸馏法提取精油,并且用GC和GC/MS方法进行分析。结果表明一年生和三年生鼠尾草精油成分和含量在不同的季节有很大的变化,精油的主要成分是侧柏酮(29.53%～49.70%),其次是樟脑(11.70%～22.72%),1,8桉叶油素(3.39%～12.08%),绿花白千层醇(4.09%～11.49%),蒎烯(0.95%～11.19%),β石竹烯(2.76%～10.58%),龙脑(1.79%～9.86%)和β芹子烯(2.94%～7.39%)。一年生和三年生鼠尾草精油含有率在整个生长季节中八月达最高,三年生鼠尾草精油含量要高于一年生鼠尾草。
The leaves of annual and perennial sage plants planted in Shanghai were extracted by steam distillation in different seasons (summer-August, autumn-October, winter-January, spring-April) GC and GC / MS methods for analysis. The results showed that the composition and content of essential oil of annual and perennial sage changed greatly in different seasons. The main constituents of essential oil were thiabendazole (29.53% -49.70%), followed by camphor (11.70% -22.72%), (0.39% ~ 11.19%), β-caryophyllene (2.76% -10.58%), dragon Brain (1.79% ~ 9.86%) and β-Paeonel (2.94% ~ 7.39%). The annual and triosyme oil content reached the highest in August throughout the growing season, and the content of the three-year-old sage oil was higher than that of annual sage.
