Secondary metabolites in plant material can be imaged in a simple and robust way by creating an imprint of the plant material on a porous Teflon surface. The Teflon surface serves to extract compounds from the plant material for enhanced desorption electrospray ionization imaging analysis, while maintaining the spatial information of the sample. The method, which remedies for limitations in mass spectrometry imaging of compounds embedded in plant material, was demonstrated on leaves and petals of Hypericum perforatum and leaves of Datura stramonium.
通过在多孔聚四氟乙烯（Teflon）表面压印植物材料，可以简单、稳健地对植物材料中的次生代谢产物进行成像。Teflon 表面用于从植物材料中提取化合物，以增强解吸电喷雾成像分析，同时保持样品的空间信息。该方法解决了植物材料中化合物的质谱成像的局限性，在贯叶连翘的叶片和花瓣以及曼陀罗的叶片上进行了验证。
