Abstract

Two flavonoids were isolated from the aerial parts of Salicornia herbacea L. by column chromatography. The structures of the flavonoid compound 1 and 2 were identified as quercetin $3-O-{\beta}-D-glucopyranoside$ and isorhamnetin $3-O-{\beta}-D-glucopyranoside$, respectively. The antioxidant activity of compound 1 was similar to those of quercetin and rutin, and the activity of compound 2, which contained methoxyl group at flavonoid B-ring, was lower than that of compound 1. The two compounds 1 and 2 were the first to be reported in this plant.

퉁퉁마디(Salicornia herbacea L.) MeOH 추출물로부터 2종의 화합물을 분리하고 DPPH 라디칼 소거 반응을 이용하여 항산화 활성을 측정하였다. UV-Vis 흡수 스펙트럼과 MS와 NMR스펙트럼으로부터 물질 1과 2는 quercetin $3-O-{\beta}-D-glucopyranoside$와 isorhamnetin $3-O-{\beta}-D-glucopyranoside$로 동정하였다. 분리된 화합물 1과 2의 DPPH 라디칼 소거 활성을 측정한 결과 1은 quercetin, rutin과 비슷한 활성을 나타내었으며, B-ring의 hydroxyl 그룹이 methoxyl 그룹으로 치환된 화합물 2는 이보다 약한 활성을 나타내었다. 화합물 1과 2는 퉁퉁마디에서는 처음으로 분리되어 보고되는 화합물이다.
