Phytoncides
Phytoncide (also phytoncide) is a collective term for a group of secondary plant metabolites . The term was first used in 1928 by the Leningrad biologist Boris P. Tokin . He wrote that it was about antibiotic substances that are used in particular to protect against pathogen infestation and thus represent an integral part of the plant's own protective system.
Since phytoncides are a very heterogeneous group of substances, it is difficult to identify commonalities that go beyond the basic characterization. What they all have in common is the growth-inhibiting or even lethal effect on pathogens. The most common basic molecular structure are the terpenes . The concentration of molecules in the air depends on the temperature and is at its maximum at approx. 30 ° C, which naturally results in a higher concentration in forests and forests in the summer than in the winter months.
