A comprehensive study on phytochemical characterization of Haplophyllum myrtifolium Boiss. endemic to Turkey and its inhibitory potential against key enzymes involved in Alzheimer, skin diseases and type II diabetes

Anti-oxidant, anti-inflammatory and enzyme inhibitory activities of 10 selected Unani herbs

“…Resulted residue was stored at 5°C for the purpose of further in vitro studies. The plant extracts were screened for total phenolics, flavonoids, tannins, and saponins using previously described methods (Zengin et al, 2014). The antioxidant activity was assessed by FRAP and ORAC method (Nile and Park, 2015).…”

Comparative study of biological activities and multicomponent pattern of two wild Turkish species: Asphodeline anatolica and Potentilla speciosa

“…The reducing power and metal-chelating activities were estimated by cupric ion reducing (CUPRAC), ferric ion reducing antioxidant power (FRAP) and metal chelating on ferrous ions 27,28 methods. The reducing power was expressed as trolox equivalents (TEs/g extract), while the metal chelating activity was expressed as EDTA equivalents (EDTAEs/g extract).…”

Anthraquinone profile, antioxidant and enzyme inhibitory effect of root extracts of eightAsphodelinetaxa from Turkey: canAsphodelineroots be considered as a new source of natural compounds?

“…The total phenolics content was determined by a reported method 27 with slight modification and expressed as gallic acid equivalents (GAEs/g extract), while total flavonoids content was determined by a reported method 28 with slightly modification and expressed as rutin equivalents (REs/g extract). HPLC analyses were performed following validated method 6 using a Waters model 600 solvent pump, a C18 column (GraceSmart RP18, 4.6 mm  150 mm, 5 mm; Grace, Deerfield, IL) at 28 ± 1 C, a 2996 photodiode array detector and Empower v.2 Software (Waters Spa, Milford, MA) was used for data acquisition in the range of 200-500 nm.…”

“…The antioxidant activity was evaluated by phosphomolybdenum and b-carotene bleaching methods 28 . Radical scavenging activities, measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and 2,2 azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS) 28 , were expressed as trolox equivalents (TEs/g extract).…”
