title: Pharmacognostic Study of the Leaves of Ptilostemon greuteri Raimondo &amp; Domina, a Rare Sicilian Paleoendemic Species
abstract: <i>Ptilostemon greuteri</i> Raimondo & Domina is a rare Sicilian paleoendemic species. The aim of study was to investigate the micro-morphological features of leaves by light and scanning electron microscopy, to elucidate the phytochemical profile of essential oil (EO), <i>n</i>-hexane (HE) and hydroalcoholic extract (HAE) by gas and liquid chromatographic methods, and antioxidant and anti-inflammatory properties by in vitro assays. Leaves had a large lanceolate blade, dark green on the upper si
