A trinorguaian-type sesquiterpenoid named kanalpin and two acylated flavonol glycosides named erzurumin and ilicanin have been isolated from Pimpinella cappadocica Boiss. & Bal., together with three known sesquiterpenoids and six known flavonoid glycosides. The structures of these compounds were determined by extensive spectroscopic (UV, IR, EI-MS, APCI-MS, HR-ESI-MS, 1D and 2D NMR) analyses. Antioxidant capacity of isolated secondary metabolites containing extracts of P. cappadocica was evaluated. (C) 2014 Phytochemical Society of Europe. Published by Elsevier B.V. All rights reserved.
