The defensive secretions of some chrysomelid beetles belonging to the genera Chrysolina, Chrysochloa, and Dlochrysa contain complex mixtures of cardenolides. The spectral data for some of these compounds suggest that they are monohydroxylated digitoxigenin derivatives linked to a pentose (such as xylose or arabinose). Evidence indicates that the beetles do not sequester these steroid glycosides from their host plants.
一些属于Chrysolina、Chrysochloa和Dlochrysa属的叶甲科甲虫的防御性分泌物含有强心甾内酯的复杂混合物。其中一些化合物的光谱数据表明，它们是与戊糖（如木糖或阿拉伯糖）相连的单羟基洋地黄毒苷衍生物。有证据表明，这些甲虫不会从其寄主植物中摄取这些甾体糖苷。
