What medicinal compounds this plant contains?
This plant contains a complex mixture of bioactive chemical constituents including valerenic acid, valeric acid, valecontiates, valepotriates, and valerenic acid. These specific compounds are primarily responsible for the sedative and anxiolytic effects associated with the herb. The sesquiterpenoids, such as valerenic acid, act as key mediators in modulating GABA receptors within the central nervous system. Furthermore, the presence of various valepotriates contributes to the overall pharmacological profile of the root extract. Together, these diverse chemical groups provide the foundation for its traditional use in treating sleep disorders and anxiety.
According to a study published by "The Journal of pharmacy and pharmacology", the species V. officinalis contains volatile oil constituents such as the monoterpene bornyl acetate and the characteristic sesquiterpene valerenic acid. These sesquiteerpenes include types that act on the amygdaloid body of the brain, while valerenic acid inhibits enzyme-induced breakdown of GABA. Non-volatile monoterpenes known as valepotriates were first isolated in 1966 and act as prodrugs that transform into homobaldrina which reduces spontaneous motility in mice. Aqueous extracts of the roots also contain appreciable amounts of GABA and the lignan hydroxypinoresinol, which can bind to benzodiazepine receptors.
The primary medicinal compounds of this plant are shown in the list below.
- valerenic acid
