The relation between lignin-related structure and antifungal activities was assessed against the white-rot fungus Trametes versicolor and two brown-rot fungi, Coniophora puteana and Rhodonia placenta. Various aromatic compounds were used to study the effect of lignin-related products. Guaiacyl and p-hydroxyphenyl units have hold greater antifungal properties than syringyl units. The presence of carbonyl and conjugated double bond increased inhibition of fungal growth, thus, highlighting the importance of the propyl chains. Furthermore, the alkylation either on phenolic or carboxylic acid moieties strongly increased fungicidal activities.

木质素相关芳香化合物对木材腐烂真菌的生长抑制

针对白腐真菌Trametes versicolor和两种褐腐真菌Coniophora puteana和Rhodonia胎盘评估了木质素相关结构与抗真菌活性之间的关系。各种芳香化合物被用来研究木质素相关产品的作用。瓜酰基和对羟基苯基单元比丁香基单元具有更大的抗真菌特性。羰基和共轭双键的存在增加了对真菌生长的抑制，因此突出了丙基链的重要性。此外，在酚或羧酸部分上的烷基化强烈增加了杀真菌活性。
