Comparative study on the antioxidant activities of extracts of Coreopsis tinctoria flowering tops from Kunlun Mountains, Xinjiang, north-western China

Listed in DataCite

Coreopsis tinctoria flowering tops (CTFs) from the Kunlun Mountains in Xinjing (north-western China) have been used for tea production for about a century.

Description

This study aims to assess the antioxidant activities and total phenolic, flavonoid and proanthocyanidin contents of various solvent extracts of CTF. CTF was extracted using n -hexane, chloroform, ethyl acetate, n -butanol, 75% aqueous ethanol (AEE) and water.

The antioxidant activities of the CTF extracts were investigated through DPPH, ABTS,

  • OH,
  • O 2 − , total antioxidant capacity and reducing power assays. The results showed that n -butanol extract showed the highest contents of total phenols and flavonoids, with DPPH, ABTS and
  • OH radical-scavenging activities with IC 50 values of 134, 90.72 and 13.8 μg mL − 1 , respectively. The AEE demonstrated the strongest DPPH and ABTS radical-scavenging activities, with IC 50 values of 103 and 75.16 μg mL − 1 , respectively. Given its high antioxidant effect, CTF is a good source of natural antioxidants or functional food materials.
