Abstract
Artemisia spp. collections, AC60, AC67, and AC77, that showed the high levels of antioxidant activities and had good growth characters and productivity, were cultivated for mass production. Using selected excellent ones, AC60, AC67, and AC77, after mass production, mugwort teas were made through rubbing and drying processes. Total phenolic compound content, nitrite scavenging ability, and SOD-like activity in mugwort teas and commercial teas were compared. Total phenolic compound content was the highest in AC67 with 109.6 mg/100 ml. Nitrite scavenging ability of AC67 tea was relatively high with 92.5% at pH 1.2 and Jasmine (98.1%), Persimmon Leaf Tea (96.4%), Green tea (98.5%), and Jakseolcha (98.7%) were very high as well. In SOD-like activity, mugwort teas, AC67 (91.7%) and AC77 (93.7%), were high as well as those of Seolrokcha (92.1%) and Rooibos Tea (93.8%). This suggests that AC60, AC67, and AC77 could be used fur making high quality teas as well as Seolrokcha, Jasmine, Green tea, Jakseolcha, Rooibos Tea, Peppermint Herb Tea.
