Verbenalin, also known as cornin, is an iridoid glycoside naturally found in plants of the *Verbena* genus, such as *Verbena officinalis*. Its chemical structure consists of an iridoid aglycone (verbenalol) linked to a glucose moiety. It is a white to off-white crystalline powder. This compound is a principal bioactive component of the traditional medicinal herb *Verbena officinalis* L. It has been extensively studied for its pharmacological activities, particularly within the central nervous system. Research indicates that verbenalin exhibits significant neuroprotective, antidepressant, and anxiolytic effects. Its mechanisms of action are believed to involve modulation of neurotransmitter systems (e.g., serotonin, norepinephrine) and anti-inflammatory pathways. Due to these properties, it is considered a promising candidate for the development of novel therapeutic agents for neurological and psychiatric disorders. Beyond its direct pharmacological potential, verbenalin serves as a crucial reference standard and marker compound for the quality control and authentication of herbal medicines derived from *Verbena officinalis*. Its isolation and characterization are also important in phytochemical research for exploring the bioactivity of iridoid glycosides.
