Scopus
Open Access Toplam 186 atıf DOI
Background: The genus Asphodeline (Liliaceae) is represented in Turkey by 20 taxa, which are traditionally used for medicinal purposes in Anatolia. Materials and Methods: In this study, we tested the phytochemical content and antioxidant effect of different solvent extracts obtained from different anatomical parts of Asphodeline anatolica. The different extracts of each plant parts were tested for antioxidant activity using different chemical assays. The total antioxidant components were also calculated. Results: Generally, acetone extracts produced the seed and root exhibited significantly higher antioxidant activity with high antioxidant components. Total phenolic content of extracts were significantly correlated with antioxidant potentials (except for, metal chelating activity). Conclusion: On the basis of the results obtained, A. anatolica extracts should be regarded as a valuable source of natural antioxidants for food and therapeutic applications.

Asphodeline lutea (L.) Rchb. is a wild edible plant, traditionally consumed in the Mediterranean diet, but there are limited literature data about its medicinal properties. Methanol extracts of A. lutea roots from Bulgarian (ALB) and Turkish (ALT) origin were evaluated for their antioxidant activity using various in vitro models: phosphomolybdenum assay, free radical scavenging activity, metal chelating activity and ferric and cupric reducing power. Both methanolic extracts were analyzed for phenolic derivatives by HPLC-DAD. Caffeic acid was the dominant phenolic acid being present up to 2.19. ±. 0.020. mg/g extract in ALB. The highest content of (+) catechin (1.54. ±. 0.060. mg/g) and (-) epicatechin (3.18. ±. 0.160. mg/g) was found in ALB as well as total polyphenolics (22.45. ±. 0.95. mg/g GAEs/g extract). The ALT revealed the highest total flavonoid content (34.99. ±. 0.39. mg REs/g extract). Free radical scavenging activity of ALB against DPPH (25.39. ±. 0.36. mg TEs/g extract) and ABTS (33.99. ±. 1.06. mg TEs/g) was evaluated. In addition, ALB had stronger metal chelating activity (7.31. ±. 0.31. mg EDTAEs/g extract) and higher ferric (34.67. ±. 0.51. mg TEs/g extract) and cupric (23.82. ±. 0.36. mg TEs/g) reduction ability as compared with the ALT. Total antioxidant capacity of ALB in phosphomolybdenum test was assayed (236.80. ±. 0.86. mg AEs/g extract). A. lutea roots have a significant potential in safeguarding against various induced oxidative stress. © 2014 Elsevier B.V.
