另外两种产物，1-（4-羟基-3，5-二甲氧基苯基）-2-丙酮和1-（4-羟基-3-甲氧基苯基）-2-丙酮，已经从枫木的水溶性木质素乙醇分解级分中分离。指出了它们的侧链和先前分离的木质素实体与通过霉菌对葡萄糖作为唯一有机底物（Raistrick和Oxford）的作用而获得的酚羧酸中存在的那些侧链的相似性。当霉菌在缺乏代谢物的情况下发挥作用时，在后一种产物的侧链性质中注意到的特定变化为支持Hibbert关于木质素在植物代谢中的生物学意义的观点提供了间接证据。
Two additional products, l-(4-hydroxy-3,5-dimethoxyphenyl)-2-propanone and l-(4-hydroxy-3-methoxyphenyl)-2-pro-panone, have been isolated from the water-soluble lignin ethanolysis fraction of maple wood. The similarity of their side-chains and those of previously-isolated lignin entities with those present in the phenol carboxylic acids obtained by the action of molds on glucose as sole organic substrate (Raistrick and Oxford) is pointed out. The specific variation noted in the nature of the side chain of the latter products when the mold functions with a shortage of metabolite provides indirect evidence in support of Hibbert''s views on the biol. significance of lignin in plant metabolism.
