18In vitro assessment of antioxidant,neuroprotective,anti-urease and anti-tyrosinase capacities of Tamarix africana leaves extracts显示文摘OBJECTIVE:To characterize the chemical profile of methanolic crude extract and its fractions(Ethyl acetate,n-butanol and aqueous)using liquid chromatographymass spectrometry(LC-MS)analysis,to evaluate their biological and pharmacological properties:antioxidant(1,1-diphenyl-2-pycrylhydrazyl(DPPH),2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic)(ABTS·+),galvinoxyle free radical scavenging,reducing power,phenanthroline andβcarotene-linoleic acid bleaching assays),enzymes inhibitory ability against several enzymes[acetylcholinesterase(AChE),buthyrylcholinesterase(BChE),urease and tyrosinase].METHODS:Secondary metabolites were extracted from Tamarix africana air-dried powdered leaves by maceration,the crude extract was fractionated using different solvents with different polarities(Ethyl acetate,n-butanol and aqueous).The amount of polyphenols,flavonoids and tannins(hydrolysable and condensed)were determined using colorimetric assays.A variety of in vitro biochemical tests were carried out to assess antioxidant and oxygen radical scavenging properties using DPPH,ABTS,galvinoxyle free radical scavenging,reducing power,phenanthroline andβcarotene-linoleic acid bleaching methods.Neuroprotective effect was examined against acetylcholinesterase and buthyrylcholinesterase enzymes.The anti-urease and antityrosinase activities were performed against urease and tyrosinase enzymes respectively.The extract’s components were identified using LC-MS and compared to reference substances.RESULTS:The results indicated that Tamarix africana extracts presented a powerful antioxidant activity in all assays and exhibited a potent inhibitory effect against AChE and BChE as well as urease and tyrosinase enzymes.LC-MS analysis identified amount of eight phenolic compounds were revealed in this analysis;Apigenin,Diosmin,Quercetin,Quercetine-3-glycoside,Apigenin 7-O glycoside,Rutin,Neohesperidin and Wogonin in methanolic extract and its different fractions of Tamarix africana from leaves.CONCLUSIONS:Based on these findings,it is reasonable to assume that Tamarix africana could be considered as a potential candidate for pharmaceutical,cosmetics,and food industries to create innovative health-promoting drugs.Esma Anissa Trad Khodja Abd El Hamid Khabtane Rabah Arhab Djamila Benouchenne Mohamed Sabri Bensaad Chawki Bensouici Ramazan Erenler 2023Journal of Traditional Chinese Medicine2023,43,2:0
