Abstract:Prunella vulgaris has long been used in traditional medicine and is consumed as a tea in China. Here, the total phenolic and flavonoid concentrations of plants from different geographical regions were measured. It was found that the total phenolic acid concentration ranged from 4.15 to 8.82 g of gallic acid equivalent per 100 g of dry weight (DW), and the total flavonoid concentration was 4.67–7.33 g of rutin equivalent per 100 g DW. Antioxidant activities were measured using 2,2‐diphenyl‐1‐picrylhydrazyl and … Show more
