Purification, Characterization, and Antioxidant Activity of Daucosterol and Stigmasterol from Prangos ferulacea

Abstract

The genus Prangos is traditionally used for medicinal and food purposes. This genus contains a wide range of bioactive metabolites. In this work, phytochemical investigation and antioxidant activity evaluation of Prangos ferulacea were carried out. Chromatographic techniques were employed for the purification of extracts components. Spectroscopic techniques such as NMR, FT-IR, together with elemental analysis, were used for the structure elucidation of isolated compounds. Stigmasterol, daucosterol, and salicylic acid were purified and identified. Isolated compounds showed moderate to high antiradical activity in DPPH antioxidant assay. Results indicated the potential of P. ferulacea as a source of steroid and their glycosides and also its possible applications as antioxidant agents.
