- Abstract
- This study was conducted to analyze bioactive compounds and the in vitro antioxidant capacity of tea infusions from whole and ground medicinal herbs, including cardamom, cinnamon, clove, nigella, and ginger. Samples of whole medicinal herbs were ground to pass through a 40 mesh (425 mu m) sieve, and hot water (95 degrees C) infusions of whole and ground herb parts were examined. Higher bioactive compounds such as phenolic compounds and flavonoids were found in the ground tea infusions. Among the medicinal herb samples, clove tea infusion showed the highest total phenol content, total flavonoid content, ABTS, and DPPH radical scavenging capacity in an average of whole and ground tea infusions. Higher beta-carotene and anthocyanin content were also found in the ground nigella and cinnamon medicinal herb tea infusion than whole infusions, respectively. Therefore, ground tea infusions may be more effective in maximizing bioactive compounds and antioxidant capacity than whole infusions.
