A study on in vitro enzyme inhibitory properties of Asphodeline anatolica: New sources of natural inhibitors for public health problems

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 growing awareness on implications related to the use of harsh chemicals and non-sustainable extraction methods of bioactive compounds from plants is causing a paradigm shift towards a more eco-friendly approach. The present study sets out to investigate the possible variation in the antioxidant, mutagenic/antimutagenic, antimicrobial, and enzyme inhibitory properties of Origanum vulgare subsp. viridulum extracts obtained using conventional, namely, maceration and Soxhlet extraction, and non-conventional, namely, ultrasound-assisted (UAE), microwave-assisted (MAE), and accelerated solvent extraction (ASE), techniques. Also, chemical characterization of these extracts were performed via ultrahigh-performance liquid chromatography and mass spectrometry (UHPLC-LTQ OrbiTrap MS) technique. A total of 58 polyphenols were identified in the tested extracts. Highest phenolic content was obtained from ASE (186.63 mg gallic acid equivalent [GAE]/g) and MAE (170.90 mg GAE/g) extracts. Maceration extract (18.89 mg rutin equivalent [RE]/g) showed highest flavonoid content. ASE extract showed highest activity in the DPPH (359.45 mg Trolox equivalent [TE]/g), ABTS (679.63 mg TE/g), FRAP (1433.94 mg TE/g), and CUPRAC (1685.72 mg TE/g) assays. In terms of enzyme inhibition, the UAE extract showed highest activity against acetyl cholinesterase (4.55 mg galantamine equivalent [GALAE]/g), butyryl cholinesterase (6.12 mg GALAE/g), and tyrosinase (173.87 mg kojic acid equivalent [KAE]/g) compared with the other extracts. The extracts exhibited significant antimutagenic and antimicrobial properties. Data collected from this study support the use of ASE and UAE in the extraction of bioactive compounds from Origanum vulgare subsp. viridulum aerial parts.
