“…In a study on the radical mopping effects of Asphodelus aestivus Brot. extracts conducted by Peksel and her colleagues, 1 mg/mL of methanolic extract exhibited a strong scavenging effect on superoxide radicals (47). These findings were found to be lower than the outcomes of the current study.…”

Objective: Eremurus spectabilis M. Bieb. is grown in East and Southeast Mediterranean regions of Turkey, and is commonly used as an edible plant in these regions. The aim of the current study was to determine the antioxidant activities of different E. spectabilis M. Bieb. extracts and some sulfur compounds. Materials and Methods:In this study, the antioxidant activities of aqueous, ethanolic, and ethyl acetate extracts of E. spectabilis M. Bieb. and sulfur compounds (α-lipoic acid, cysteamine, cysteine, diallyl sulfide, glutathione, homocysteine, N-acetyl cysteine, vitamin U and 1,4-dithioerythritol) were assessed in several antioxidant tests. These tests included reducing power, cupric ion reducing antioxidant capacity, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging, 2,2-diphenyl-1-picrylhydrazyl radical scavenging, N,N-dimethyl-4-phenylenediamine dihydrochloride radical scavenging, superoxide anion radical scavenging, hydroxyl radical scavenging, metal chelating activities and ferric ion reducing antioxidant power. The phytochemical profiles and total phenolic and flavonoid contents of all extracts were investigated.Results: It was found out that the antioxidant activities of all the extracts and sulfur compounds generally increased with concentration increases, the highest antioxidant activity was found in ethyl acetate extract, while the aqueous extract was found to have the lowest antioxidant activity. Diallyl sulfide was found to have the highest antioxidant activity, whereas vitamin U had the lowest antioxidant activity. It was observed that all extracts of E. spectabilis M. Bieb. and the sulfur compounds showed antioxidant activity. Conclusion:The E. spectabilis M. Bieb. and sulfur compounds investigated in this study could be considered as a source of antioxidants.

Plant-based systems continue to play an essential role in healthcare, and their use by different cultures has been extensively documented. Asphodelus L. (Asphodelaceae) is a genus of 18 species and of a total of 27 species, sub-species and varieties, distributed along the Mediterranean basin, and has been traditionally used for treating several diseases particularly associated with inflammatory and infectious skin disorders. The present study aimed to provide a general review of the available literature on ethnomedical, phytochemical, and biological data related to the genus Asphodelus as a potential source of new compounds with biological activity. Considering phytochemical studies, 1,8-dihydroxyanthracene derivatives, flavonoids, phenolic acids and triterpenoids were the main classes of compounds identified in roots, leaf and seeds which were correlated with their biological activities as anti-microbial, anti-fungal, anti-parasitic, cytotoxic, anti-inflammatory or antioxidant agents.

“…Similarly, Daniels et al [33] found an increase in non-enzymatic antioxidant capacity based on total polyphenol content in bulbs and roots of South African bulbous geophyte Gethyllis multifolia L. Bolus under drought stress. Additionally, Peksel et al [34] showed that Asphodelus aestivus has powerful antioxidant activity that is based on non-enzymatic antioxidants. In our study, the high APX, CAT and SOD activities in the root tubers of A. aestivus can be related to this plant's life cycle, which consists of an active phase (autumn-late spring) and an inactive (summer) phase [19,24].…”

Asphodelus aestivus Brot. (Walter) is the dominant geophyte species on degraded areas of eastern Mediterranean Basin. Because it has a stress-tolerant strategy and it is a competitive ruderal. We studied the activities of antioxidant enzymes (ascorbate peroxidase, APX; superoxide dismutase, SOD; catalase, CAT) in the root tubers of A. aestivus from Bursa, Turkey over one year. There was a seasonal variation in antioxidant enzyme activities. The CAT and APX showed similar variation model in which the activity was highest in July (9.3 ± 2.7 units/mg protein and 141.9 ± 52.7 units/mg protein) and lowest in August (1.2 ± 0.6 units/mg protein and 14.5 ± 2.3 units/mg protein). The SOD activity increasing in summer months was reached up the highest level in late summer (297.6 ± 48.1 units/mg protein). The significant negative correlations were also found between enzyme activities and water contents of soils (p<0.05). The increased antioxidant enzyme activities in summer and late summer periods may be a protective and acclimation mechanism against drought stress. These results indicate that drought can induce enzymatic antioxidant defence system in A. aestivus and this system may help to this species to spread on degraded Mediterranean environments.
