Phytochemical analysis on the leaves of Teucrium capitatum L. subsp. capitatum collected in the Botanical Garden of Rome

In this paper, the phytochemical study on the leaves of Teucrium capitatum L. subsp. capitatum collected in the Botanical Garden of Rome was presented for the first time. Nine secondary metabolites were evidenced i.e., pheophytin a (1), verbascoside (2), alyssonoside (3), apigenin (4), cirsimaritin (5), cirsiliol (6), 8-O-acetyl-harpagide (7), teucardoside (8) and quinic acid (9). Their presence is perfectly in accordance with previously published general results on the species, thus confirming the phytochemical knowledge on it.
