Abstract：
Three mature Eucalyptus globulus trees with 40 years of age were studied at three height levels (0%, 35%, and 60% of total tree height) and at three radial regions (sapwood, inner and outer heartwood). The composition of lipophilic extracts was evaluated and an extensive list of 202 compounds was reported for the first time. The fatty acids were the major chemical family, representing 40.8% of the total compounds, followed by phytosterols (19.0%), aromatics (10.5%) and triterpenes (10.4%). Saturated fatty acids accounted for 74.2% of total compounds (C16:0, C24:0 and C26:0 were predominant), β-Sitosterol and stigmastanol were the main sterols (80 and 7% respectively), while aromatics were mainly represented by syringic acid, 4-hydroxy-3,5-dimethoxybenzaldehyde, vanillic acid, and vanillin. The main triterpenes were asiatic and arjunolic acids.
摘要：
在三个高度水平（0％，35%,和总树高的60%)，并且在三个径向区域(边材，内部和外部心材)。评估了亲脂性提取物的组成，首次报道了202种化合物的广泛列表。脂肪酸是主要的化学家族，占总化合物的40.8%，其次是植物甾醇（19.0%），芳烃(10.5%)和三萜(10.4%)。饱和脂肪酸占总化合物的74.2%(以C16:0、C24:0和C26:0为主),β-谷甾醇和stigmastanol是主要的甾醇（分别为80％和7％），而芳烃主要以丁香酸为代表，4-羟基-3,5-二甲氧基苯甲醛,香草酸,还有香草醛.主要的三萜是亚麻酸和空萜酸。
