The essential oil of leaves and peel from the Cretan variety Zambetakis (Citrus limon) was obtained by steam distillation with a Clevenger apparatus. The essential oil was subjected to GC-MS analysis, and 35 substances were identified. The main component in both essential oils was limonene. beta-Pinene, myrcene, neral, geranial, neryl acetate, geranyl acetate, and beta-caryophyllene have been identified in the leaf oil. The peel oil contained gamma-terpinene, beta-pinene, myrcene, neral, and geranial. The quantification of volatile substances was based on the internal standard method, using octyl acetate as internal standard, and expressed in milligrams per kilogram of the essential oil. The high contents of neral and geranial were indicative of the high quality of both essential oils. The aroma profile and quantitative variations among the essential oil components were measured at six different time intervals over a period of greater than one year. Differences between the components of lemon leaves and peel were observed.
采用克利夫enger装置通过水蒸气蒸馏法从克里特岛品种赞贝塔基斯（Citrus limon）的叶子和果皮中提取精油。对该精油进行气相色谱 - 质谱联用（GC - MS）分析，鉴定出35种物质。两种精油的主要成分均为柠檬烯。在叶油中已鉴定出β-蒎烯、月桂烯、橙花醛、香叶醛、乙酸橙花酯、乙酸香叶酯和β-石竹烯。果皮油含有γ-萜品烯、β-蒎烯、月桂烯、橙花醛和香叶醛。挥发性物质的定量基于内标法，使用乙酸辛酯作为内标，并以每千克精油中的毫克数表示。橙花醛和香叶醛的高含量表明两种精油的品质都很高。在一年多的时间里，在六个不同的时间间隔测量了精油成分的香气特征和定量变化。观察到柠檬叶和果皮成分之间的差异。
