摘要：

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.
