초록

식물 20종을 메탄올로 추출하여 양성자 빔 조사 에너지양(1, 5, 10 KGray)에 따른 항산화 활성 능을 탐색 하고자 DPPH 라디칼 소거활성과 ABTS free 라디칼 소거 활성에 대하여 조사하였다. 양성자 빔 조사 시 15종류는 활성이 증가하였으나 10 KGray에서 흑축(Pharbitis nil Choisy)은 활성이 감소하였으며, 4종류는 활성변화가 없었다. DPPH 라디칼 소거활성은 1 및 5 KGray에서 유근피(Ulmus macrocarpa) (84 %), 10 KGray (85 %)로 가장 높았으나 10 KGray에서 흑축(Pharbitis nil Choisy)은 6 % 감소하였다. $IC_{50}$값을 무처리구와 빔 조사량에 대한 활성을 비교하면 1 KGray에서 산약(Dioscorea batatas Decne.) 6.3배, 5 KGray에서 천화분(Trichosanthes kirilowii Max.) 2.1배, 산약(Dioscorea batatas Decne.) 2.8배 증가하였다. ABTS free 라디칼 소거활성에서 1 KGray의 양성자 빔 에너지를 조사 했을 경우, 가자(Terminalia chebula Retzius)는 60 % 증가하였다. $IC_{50}$값은 1 KGray 빔 조사 시 0 KGray보다 마황근(Ephedra sinica Stapf) 2.0배, 가자(Terminalia chebula Retz.) 2.5배, 우방자(Arctium lappa Linne) 2.4배 증가하였다.

20 species of plants were extracted with Methanol and were investigated for DPPH radical scavenging activity and ABTs free radical scavenging activity to quest anti-oxidation ability depending on the proton beam irradiation quantity. In the proton beam irradiation, 15 species's activities increased but among them, Pharbities nil Choisy decreased at 10 KGray and 4 species' activity didn't change at all. In hydrogen ion radical elimination activity, Ulmus macrocarpa (84 %) showed the highest and Pharbitis nil Choisy showed 6 % decreasing at more than 1 KGray. By comparison with untreated $IC_{50}$ value, the beam-treated $IC_{50}$ value increased 6.3 times for Dioscorea batatas Decne. at 1 KGray, 2.1 times for Trichosanthes kirilowii Max., and 2.8 times for Dioscorea batatas Decne. at 5 KGray. In ABTs free radical elimination activity, the activity increased 60 % for Terminalia chebula Retzius compared with untreated one. Besides, the beam-treated $IC_{50}$ value increased 2 times for Gray Ephedra sinica Stapf, 2.5 times for Terminalia chebula Retz. and 2.4 times for Arctium lappa Linne at 1 KGray.
