The phytochemical analysis on the aerial parts of Teucrium capitatum L. collected from a new population in Central Italy, led to the identification of eight compounds, i.e. pheophytin a (1), poliumoside (2), apigenin (3), luteolin (4), cirsimaritin (5), cirsiliol (6), 8-O-acetyl-harpagide (7) and teucardoside (8) belonging to four different classes of secondary metabolites. Pheophytin a (1) represents a newly identified compound in the genus whereas compounds (7–8) are newly identified compound in the species. The chemotaxonomic and ethnobotanical aspects relative to the presence of these compounds were widely discussed suggesting important conclusions for both. [ABSTRACT FROM AUTHOR]

AbstractIn this paper, the first complete phytochemical analysis of an Italian specimen of Araucaria cunninghamii Mudie led to the identification of six secondary metabolites, one of which was identified in the species for the first time. The chemophenetic and ethnobotanical evaluations of this specimen are widely discussed. [ABSTRACT FROM AUTHOR]
