“…Plantain ( Plantago lanceolata ) has been used since ancient times in traditional medicine, either as such or in the form of tinctures, decoctions, or infusions. At the base of the medicinal properties are the active principles [ 1 , 2 , 3 , 4 , 5 ], with antioxidant, and antitumor properties [ 6 , 7 , 8 , 9 ] as polysaccharides [ 10 , 11 , 12 ], polyphenols [ 3 , 5 , 8 ] alkaloids, terpenoids (ursolic acid, oleanolic acid), caffeic acid derivatives (plantamajoside, acteoside or verbascoside), iridoid glycosides (aucubin, catalpol), fatty acids (palmitic acid, linolenic acid, linoleic acid, myristic acid), vitamins [ 1 , 2 , 3 ], macroelements and microelements [ 13 ]. Analytical studies performed on the essential oil obtained by hydrodistillation from the leaves of Plantain showed that it contains a wide range of organic compounds, with fatty acids representing about 41% of the oils fraction [ 2 ].…”
