Phenolic content and antioxidant activity of Nepeta nuda subsp. albiflora Boiss. were reported in this study. The ethanol and water extracts of Nepeta nuda subsp. albiflora were prepared and used for biochemical analyses. Antioxidant capacities of the extracts were evaluated by three different in vitro bioanalytical methods including a reducing antioxidant method and two radical scavenging antioxidant...
The identification and quantification of phenolic compounds of Stachys lavandulifolia Vahl. var. brachydon Boiss. by LC-MS/MS (Liquid Chromatography- tandem Mass Spectrometry) technique is the main purpose of the current study. The high concentrations of quinic acid (2534± 12 ppb) and chlorogenic acid (1882±92 ppb) were detected by LC-MS/MS.. Another goal of the study is to evaluate the antioxidant...
The main objective of the current work is to search the antioxidant activities of Origanum acutidens leaves by using DPPH, FRAP and CUPRAC methods severally. Three well known antioxidant compounds (BHA, BHT and ascorbic acid) were used as standards for comparing the extracts. Also, phenolic compounds of Origanum acutidens leaves were identified by UHPLC-ESI-MS/MS. The high concentrations of rosmarinic...
