Zinke s contribution to organic chemistry include research on natural resins, e.g. the isolation of siaresinol and sumaresinol acids which he showed to be triterpenes. Most of his research, however, was devoted to highly condensed aromatic ring systems (today called PAHs), particularly perylene. He became acquainted with these ring systems during his work on alizarines with R. Scholl, and interestingly, the last three papers he published in the sixties also dealt with perylene and its derivatives , namely parts 64-66 of this series.
