• The antioxidant activity of Crataegus monogyna extracts and flavonoids (chlorogenic acid, hyperoside, rutin, quercetin, vitexin-2O-rhamnoside, epicatechin, catechin, and procyanidin B2) quantitatively was determined using the method of spectrophotometry (diphenyl-1-picrylhydrazyl (DPPH·) radical scavenging assay and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid)(ABTS·+) radical cation decolorization assay).

  • 7 The major constituents of Crataegus species are flavonoids, oligomeric proanthocyanidins (OPCs) and some phenolic acids which are well-known for their antioxidant properties. (ivsajournals.com)
  • Conclusion: These findings indicated that doxorubicin can adversely damage the testicular tissue, while Crataegus co-administrationcould effectively prevent these adverse effects by effective inhibiting oxidative processes and restoration of antioxidant defense system. (ac.ir)
