Abstract

Abstract: Seventeen compounds were isolated from the aerial parts of Sheareria nana S. Moore. Their structures were elucidated by spectroscopic methods and by comparison of the reported spectral data. They consisted of two sterols (1 and12 ), five triterpenoids (2–6 ), two lignanoids (7 and16 ), two diterpenoids (8 and9 ), two phenylpropanoids (10 and11 ), three flavonoids (13, 15 and17 ) and one quinone (14 ). The taxonomic influence of these compounds in the position of this species within the Compositae family was discussed. As the result, the neo-clerodane diterpenes (soulidiol and soulidiol 18-O-β-D-glucoside), sterol (α-spinasterol-3-O-β-D-glucoside) and triterpenoids (urs-12-ene and olean-12-ene) might depict the taxonomic position for S. nana in Compositae and demonstrate the relationships between S. nana and some species of Astereae and Inuleae. Highlights: We studied the chemical constituents of Sheareria nana and obtained seventeen compounds. The structures of these compounds were elucidated by spectroscopic methods. The obtained compounds indicated that S. nana might have some relationships with some species of Astereae and Inuleae.
