Phytochemical and microscopial analysis of leaves and stems of various species of Encelia showed a strict correlation between the presence of resin ducts and the accumulation of benzopyrans and benzofurans. Fluorescence microscopy of Encelia farinosa proved unambigously that these compounds are stored exclusively in the resin ducts and the surrounding cells.
对多种恩西利亚属植物的叶子和茎进行的植物化学和显微镜分析表明，树脂道的存在与苯并吡喃和苯并呋喃的积累之间存在严格的相关性。对粉叶恩西利亚的荧光显微镜检查明确证明，这些化合物仅存储在树脂道及其周围细胞中。
