Toplam 133 atıf DOI
Asphodeline species are traditionally used as food and medicines. The different extracts (acetone, methanol and water) from different parts (stem, root, seed and leaf) of Asphodeline anatolica were screened for inhibitory potentials on cholinesterase, tyrosinase, α-amylase and α-glucosidase. Enzyme inhibitory effects were investigated by using microplate reader. All studied extracts exhibited remarkable inhibitory effects on the tested enzymes. Generally, acetone and methanol extracts have higher potentials than water extracts. Also, the enzyme inhibitory activities of the extracts varied significantly according to the plant parts as well as the solvent used. R-Met (7.42. mgGALAEs/g extract) and St-Ac (10.74. mgGALAEs/g extract) had the highest acetylcholinesterase and butrylcholinesterase inhibitory activity, respectively. R-Met (22.48. mgKAEs/g extract) exhibited the strongest tyrosinase inhibitory effects, while Se-Ac had the most potent activity on both α-amylase (2.53. mmolACAEs/g extract) and α-glucosidase (6.70. mmolACAEs/g extract). The results suggested that the A. anatolica extract may be useful for food and medicinal applications.

The scientific world tends to turn to natural products such as medicinal and aromatic plants because of the inadequacy of commercially available synthetic drugs as antibiotics or anticancer, and their adverse effects on healthy tissues. One of these plants is Daphne gnidioides Jaub. & Spach, which belongs to the Thymelaeaceae family, and there is no data in the literature on its biological activity. This study is aimed to elucidate the chemical profiles and in vitro anticancer, antibacterial and DNA protection and enzyme inhibitory properties of methanol extracts of root, stem, and leaf of D. gnidioides Jaub. & Spach. Polyphenolic components of the extracts were characterized by HPLC-MS/MS. The highest phenolic content was detected in the leaf extract (TIPC = 43.5 ± 0.5 mg/g DE), followed by stem (TIPC = 27.3 ± 0.7 mg/g DE) and root (TIPC = 18.3 ± 0.2 mg/g DE) extracts. Vicenin-2 and 3-O-p-coumaroyl-5-O-caffeoylquinic acid were the main identified compounds in leaf and both root and stem extracts, respectively. The extracts did not show any protective effect on DNA against experimental Fenton's reagent. The minimum inhibitory concentration and the minimum bactericidal concentration values for the root and leaf extracts against tested bacterial strains ranged from 31.25 to 500 μg/mL. After 48 h interaction of the cancer cell lines with the extracts, only the stem extract had significant cytotoxicity on HeLa cells (IC50 = 86.16 μg/mL). No remarkable activity of the extracts, which was tested against MDA-MB-231, was detected (IC50 > 1000 μg/mL). These data showed that D. gnidioides Jaub. & Spach stem extract inhibited the survival of HeLa cells in a time-dependent manner. After the treatment of IC50 concentration of stem extract with HeLa cells, an increase in LC3-II autophagic gene expression was detected. Also, the extracts exhibited significant tyrosinase inhibitory effects which were confirmed by molecular docking. To sum up, the tested extracts could be used as a starting point for the development of new multifunctional drugs.
