Introduction: Pedicularis sibthorpii and P. wilhelmsiana are endemic species mainly found in North-West of Iran. Plants of genus Pedicularis produce some important polyphenols and flavonoids. In the present work, total phenol and flavonoid contents of the mentioned species as well as their antioxidant capacity have been evaluated. Methods: Methanol extract of samples was fractionated by SPE method using an ODS cartridge and their 1H-NMR spectra were recorded. Total phenols and flavonoids of methanol extracts were...
