Exudates of the rosid clade of the eudicots have been surveyed and characterized by carbon-13 and proton nuclear magnetic resonance spectroscopy. Of 554 samples divided roughly equally between the subclades fabids and malvids, about two-fifths are resins, a third gums, one-ninth gum resins, one-twelfth kinos, and the remaining not affiliated with these four main molecular classes. Two small new molecular classes, respectively from the Clusiaceae (xanthics) and the Zygophyllaceae (guaiacs), are identified and described.
已通过碳-13 和质子核磁共振波谱法对真双子叶植物蔷薇分支的渗出物进行了调查和特性描述。在大致等分的 554 个样本中，有大约五分之二是树脂，三分之一是树胶，九分之一是胶树脂，十二分之一是血竭，其余则与这四个主要分子类别没有关联。分别从藤黄科（黄烷类）和蒺藜科（愈创木烷类）鉴定并描述了两个新的小类分子。
