研究了枳实叶片可溶性角质层脂质的组成。通过气相色谱-质谱法鉴定并定量。主要成分为1-烷醇（C24-C40）、正烷基酯（C36-C56）、正烷酸（C28-C34）、正烷烃（C22-C40）和三萜酮，而正烷醛（C29-C38）、甾醇和烷基苯（分子量260、274和288）贡献较小。叶龄和叶位显著影响SCL的数量组成。白天温度升高，在叶的发展导致每单位面积的正构烷烃，1-链烷醇，正链烷酸和正烷基酯的量减少，而夜间温度升高导致正构烷烃，正链烷酸和1-链烷醇的量增加。相对湿度对SCL的含量和组成没有影响。角质膜对水的渗透性（本文第一部分所述）与SCL的组成无关。本文提出了一个植物铜转运限制屏障的分子结构模型和水的转运模型。
The constituents of the soluble cuticular lipids (SCL) of the leaf blades of Citrus aurantium L. were identified by gas chromatography-mass spectrometry and quantified. Major components were 1-alkanols (C24 to C40), n-alkyl esters (C36 to C56), n-alkanoic acids (C28 to C34), n-alkanes (C22 to C40) and triterpenones, while n-alkanals (C29 to C38), sterols, and alkyl benzenes (molecular weights 260, 274 and 288) made minor contributions. Leaf age and side significantly affected the quantitative composition of SCL. Increased day temperature during the development of leaves led to decreased amounts per unit area of n-alkanes, 1-alkanols, n-alkanoic acids and n-alkyl esters while increased night temperatures resulted in increased amounts of n-alkanes n-alkanoic acids and 1-alkanols. Relative humidity had no effect on the amounts or composition of SCL. The permeability of cuticular membranes to water (described in part I of this paper) and the composition of SCL were not related. A model for the molecular structure of the transport-limiting barrier of plant cuticles and for the transport of water across it is proposed.
