Abstract
Background:
Teucrium hyrcanicum belonging to the Lamiaceae family is a native plant in Iran; it is called Maryam nokhodi-e-jangali in Farsi.
Objective:
The aim of this study is to evaluate acetylcholinesterase inhibition (AChEI), antioxidant activity and flavonoids content of T. hyrcanicum methanol extract.
Materials and Methods:
The air-dried and the ground aerial parts of T. hyrcanicum were extracted by percolation method with methanol. Antioxidant activity of the extract was investigated by using 2,2'-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power assay (FRAP) methods. In addition, AChEI and flavonoid content of T. hyrcanicum methanol extract were measured.
Results:
The results showed that total flavonoid content of T. hyrcanicum in reference to the standard curve for quercetin was 20.70 ± 0.05 mg quercetin equivalents/g of extract. In the FRAP method, the antioxidant activity of T. hyrcanicum extract and butyl hydroxyanisole (BHA) (as a positive control) were 657.5 ± 0.04 and 880 ± 0.06 mmol Fe II/1 g dried extract. According to results of DPPH assay, half maximal inhibitory concentration (IC50) value for DPPH radical-scavenging activities of T. hyrcanicum methanol extract, vitamin E and BHA were 74.6, 14.12 and 7.8 μg/mL, respectively. IC50 value for AChEI of T. hyrcanicum and donepezil as a positive control were 2.12 mg/mL and 0.013 mg/mL.
Conclusion:
The results of the present study showed T. hyrcanicum is a natural antioxidant that the flavonoid content can be responsible for extract effects.
