Total phenol content was obtained from the stem extract of 7.8 (g/100g, D.W.) and root extract of 10.5 (g/100g, D.W.) on Rosa rugosa. S-4 and R-2 compounds were isolated from the stem and root of R. rugosa. The structure of S-4 and R-2 compounds was assigned as catechin by $^{1}H,;^{13}C$ CNMR signal and TOF-MS. The tannin content of stem extract was 752.5 (mg/100g, D.W.) as 6.3 of gallic acid, 61.5 of epicatechin and 684.8 of catechin. The tannin content of root extract was higher about 2 times (1676.0) as 6.8 of gallic acid, 160.3 of epicatechin and 1508.5 of catechin than that of stem. It was shown that catechin was main compound in the stem and root extracts of R. rugosa. Antioxidant activities were stronger low concentration, and were not different of stem and root extracts. As the results, stem and root of R. rugosa were evaluated, as natural antioxidant resource.
