Summary

Barley tea contains novel phenolic compounds with potent antioxidant properties. Several compounds, including 3,4-dihydroxybenzaldehyde and quercetin, demonstrated superior peroxynitrite-scavenging activity compared to butylated hydroxytoluene.

Area of Science:

  • Food Chemistry
  • Pharmacology
  • Natural Products

Background:

  • Barley tea is a popular beverage with potential health benefits.
  • Phenolic compounds are known for their antioxidant properties.
  • Identifying bioactive compounds in traditional beverages is crucial for understanding their efficacy.

Purpose of the Study:

  • To identify and quantify phenolic compounds in barley tea.
  • To evaluate the antioxidant capacity of identified compounds.
  • To compare the efficacy of these compounds against a known antioxidant, butylated hydroxytoluene (BHT).

Main Methods:

  • High-performance liquid chromatography (HPLC) was used for compound identification.
  • Spectrophotometric methods were employed to assess peroxynitrite-scavenging activity.

  • Antioxidant activity was measured at a concentration of 400 microM.
  • Main Results:

    • Five new phenolic compounds were identified in barley tea: p-hydroxyacetophenone, 5,7-dihydroxychromone, naringenin, quercetin, and iso-americanol A.
    • Known compounds such as p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, p-hydroxybenzoic acid, vanillic acid, and p-coumaric acid were also detected.
    • 3,4-dihydroxybenzaldehyde, p-coumaric acid, quercetin, and isoamericanol A exhibited stronger peroxynitrite-scavenging activity than BHT.

    Conclusions:

    • Barley tea is a rich source of diverse phenolic compounds, including novel ones.
    • Several phenolic compounds in barley tea possess significant antioxidant properties.
    • These findings suggest barley tea and its constituents may offer health benefits due to their antioxidant potential.
