This study was carried out to help restore and spread broaden the consumption of Chungtaejeon, a our traditional tea, Chungtaejeon in Korea, and as well as to gather the basic data on Chutaejeon tea. We have also compared the various ingredients components and physiological activities of Chungtaejeon tea extracts with that of green tea extracts. According to the results, the total phenol contents in of the Chungtaejeon and green tea extracts were 90.56 and 98.70 ㎎/100 mL, respectively, and their tannin contents levels in Chungtaejeon and green tea extracts were 214.14 ㎎/100 mL and 259.60 ㎎/100 mL, respectively, showing a difference in content. The catechin contents of the Chetaejeon and green tea extracts were in the order of EGC(15.80~16.50 ㎎/100mL), EGCG(10.40~10.60 ㎎/100 mL), and ECG(9.55~9.88 ㎎/100 mL), however, with the exception of EC(7.86 ㎎/100 mL) in the green tea extracts, there were not significantce differences between that in them Chetaejeon and green tea extracts. Quercetin was the main flavonoid ingredient component in those both the Chungtaejeon and green tea extracts was quercetin, at levels of 0.08 ㎎/100 mL and 0.06 ㎎/100 mL and its contents in Chungtaejeon and green tea extracts were 0.08 ㎎/100 mL and 0.06 ㎎/100 mL, respectively. The primary amino acid in both tea extracts was theanine main amino acid at levels of, theanine contents were most increased in 8.02 ㎎/100mL and 10.80 ㎎/100 mL, respectively, Chungtaejeon tea extracts by 8.02 ㎎/100 mL and green tea extracts by 10.80 ㎎/100 mL. And the arginine contents of the Chungtaejeon and green tea extracts in Chungtaejeon and green tea extracts were 1.78 ㎎/100 mL and 1.86 ㎎/100 mL, respectively. In terms of mineral composition, potassium content was highest contents in the Chungtaejeon and green tea extracts by 19.80 and 18.04 ㎎/100 mL, respectively. Finally, the Chungtaejeon tea extracts offered the greatest anti-oxidation and ACE inhibition activities were most increased in the Chungtaejeon tea extracts, and the green tea extracts showed the highest level of nitrite radical scavenging activity at 90% was extremely much increased in the green tea extracts by 90%
