A common role of secondary metabolites in plants is defense mechanisms.

Many of these secondary metabolites are known to have medicinal properties.

In addition, a second secondary metabolite citrinin is produced as well.

Most of the drugs used by humans were originally discovered as plant secondary metabolites.

A secondary metabolite is not directly involved in those processes, but usually has an important ecological function.

Secondary metabolites are often characterized as either qualitative or quantitative.
