Antioxidative and Anti-Glycation Activity of Buckwheat Hull Tea Infusion

The utilization of buckwheat hull for the preparation of buckwheat hull tea was addressed in this study. The total phenolics content, flavonoids profile, antioxidant capacity, and anti-glycation activity of buckwheat hull tea were compared to those of green tea. The buckwheat hull contained rutin, quercetin, and C-glucoflavones; however, the total phenolic content was significantly lower in comparison to green tea leaves. Rutin and vitexin were the main flavonoids found in buckwheat hull tea. The buckwheat hull tea showed lower antioxidant capacity and inhibitory activity against the formation of fluorescent advanced glycation end products as compared to green tea.
