The cuticle is one of the most important plant barriers. It is an external and continuous lipid membrane that covers the surface of epidermal cells and whose main function is to prevent the massive loss of water. The spectroscopic characterization of the plant cuticle and its components (cutin, cutan, waxes, polysaccharides and phenolics) by infrared and Raman spectroscopies has provided significant advances in the knowledge of the functional groups present in the cuticular matrix and on their structural role, interaction and macromolecular arrangement. Additionally, these spectroscopies have been used in the study of cuticle interaction with exogenous molecules, degradation, distribution of components within the cuticle matrix, changes during growth and development and characterization of fossil plants.
表皮是最重要的植物屏障之一。它是覆盖表皮细胞表面的连续的外部脂质膜，其主要功能是防止大量水分流失。通过红外和拉曼光谱对植物表皮及其成分（角质、角质素、蜡、多糖和酚类）的光谱特性进行了研究，为角质层基质中存在的功能基团及其结构作用、相互作用和高分子排列提供了重要的认识。此外，这些光谱学还被用于研究角质层与外源分子的相互作用、降解、角质层基质中成分的分布、生长发育过程中的变化以及化石植物的特征描述。
