HPLC and NMR analysis of the phenyl-ethanoid glycosides pattern of Verbascum thapsus L. cultivated in the Etnean area
In this work the HPLC and NMR analysis of the phenyl-ethanoid glycosides (PhGs) pattern of a cultivated exemplar of Verbascum thapsus L. (Scrophulariaceae) from the Etnean area (Sicily, Italy) was performed in order to verify their possible presence. Wild V. thapsus is well-known in ethnopharmacology due to the several beneficial effects that it is able to exert and which are primarily due to these compounds. So, it’s extremely important that also cultivated exemplars of this species biosynthesize them in order to maintain their pharmacological properties.
