对桃金花边材组织的研究表明，桃金娘素及其衍生物基本上不存在于健康组织中，只有在真菌感染后才以植物保卫素的形式产生。共鉴定出5种联苯类化合物：桃叶珊瑚素、2‘-甲氧基桃叶肝素、4’-甲氧基桃叶肝素、2‘-羟基桃叶肝素和2’-羟基-3，5-二甲氧基联苯。后者是一种新的植物抗毒素。一项对II棵花椒树的调查表明，并非所有这些化合物都是在植物抗毒素反应中产生的。
An examination of the sapwood tissue of Sorbus aucuparia L. has revealed that aucuparin and its derivatives are essentially absent from healthy tissue, and are only produced as phytoalexins following fungal infection. Five biphenyls were identified: aucuparin, 2'-methoxyaucuparin, 4'-methoxyaucuparin, 2'-hydroxyaucuparin and isoaucuparin (2'-hydroxy-3,5-dimethoxybiphenyl). The latter is a new phytoalexin. A survey of II individual Sorbus trees showed that not all these compounds are necessarily produced in the phytoalexin response.
