Aucubin is a common secondary plant substance from the group of iridoids. It is a glycoside of the aglycone Aucubigenin and a glucose unit. Like other monoterpenes the aglycone of two isoprene units is synthesized with five carbon atoms in the plant. In contrast to the C10 - base body of the iridoids Aucubingrundgerüst has only nine carbon atoms, as a methyl group is oxidized during biosynthesis to the carboxylic acid group, and then split off as carbon dioxide.

Aucubin has antibiotic properties. The juice of plantain contains aucubin and does not mold. Moldy The juices of most other plants. Aucubin reduces inflammation and sooth. By placing of crushed plantain leaves the itching and the swelling can be alleviated by insect bites. The semi parasite eyebright and mullein (wool flower ) also contain aucubin. They are anti-inflammatory. However, the aucubin is retained only after a very thorough extraction. Spitz ways Richtee has often lost due to improper drying or storing the aucubin. Aucubin makes the tea bitter. Since it is decomposed by intestinal bacteria, it is tea without pharmacological effect.
