What medicinal compounds this plant contains?

This plant contains the medicinal compounds acteoside (verbascooside), aucubin, catalpol, iridoid glycosides, and plantagomain. These specific chemical constituents are primarily classified as iridoid glycosides, which contribute to the plant's biological activity. Within this group, aucubin and catalpol serve as significant bioactive markers used in pharmacological studies. The presence of acteoside further enhances the medicinal profile of the species through its potential antioxidant properties. Together, these various compounds define the complex phytochemical makeup of the Plantaago major leaves.

According to a study published by "Electrophoresis", the plant Plantago major contains four chief bioactive metabolites that can be quantified from water extracts. These metabolites include the iridoid glycosides aucubin and catalpol, along with the phenylethanoid glycosides acteoside and plantamajoside. The analytical method used for these substances utilizes a background electrolyte consisting of 15 mM sodium tetraborate, 20 mM TAPS, and 250 mM DOC at pH 8.50. This specific method allows for the separation of the analytes within 20 min. The study confirms that the method is suitable for analyzing leaf extracts of this species.
