Penicillium spinulosum grown in a Czapek-Dox medium containing glucose produces two phenolic substances: 4-methyl orcinol (beta-orcinol) and 3-methyl orsellinic acid (beta-orcinolcarboxylic acid). Their isolation and identification are described. They are considered to be precursors of quinoids occuring in aged media and responsible for their red-violet colours. Preliminary results indicate that one of the quinoid compounds may be a diphenoquinone.
4-甲基苔黑酚（β-苔黑酚）和3-甲基苔色酸（β-苔黑酚羧酸）。文中描述了它们的分离和鉴定过程。它们被认为是老化培养基中醌类物质的前体，并导致培养基呈现红紫色。初步结果表明，其中一种醌类化合物可能是二酚醌。
