Abstract

The genus Lespedeza belonging to Leguminosae is an annual or perennial herb, which has been used as a Chinese herbal medicine. Antioxidant activity on DPPH ((1,1)-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylenebenzothiazoline-6-sulfonic acid) radicals and the contents of total polyphenol and flavonoid were analyzed with 12 methanol extracts from six Lespedeza genus plants with different plant parts. The highest content of total polyphenol was detected in the leaves of Lespedeza$\times$robusta (194.6 mg GAE/g), while the highest content of total flavonoid existed in the aerial part of Lespedeza thunbergii var. intermedia (47.9 mg QE/g). Generally, the amounts of polyphenol and flavonoid compounds were higher in the leaves than in the stems. The $SC_{50}$ value of DPPH radical scavenging activity ranged from 10.16 to 90.94 ppm, of which the strongest activity was determined in the leaves of L. robusta. Most ABTS radical scavenging activities from the investigated methanol extracts were higher than that of L-ascorbic acid, implying the excellent antioxidant activity. The radical scavenging activity in this study showed high correlation with the amount of total polyphenol rather than that of total flavonoid. These data suggest that the methanol extracts from these Lespedeza spp. could be potential candidates for natural antioxidants.

본 실험에서는 국내에 자생하는 콩과에 속하는 6종의 싸리속 식물의 각 부위별 추출물로부터 총 폴리페놀, 총 플라보노이드 함량을 측정하였고, DPPH, ABTS 라디칼 소거능을 조사하였다. 폴리페놀성 화합물은 고양싸리의 잎(LR-L)에 가장 많이 포함되어 있는 것으로 조사되었고, 플라보노이드 화합물은 풀싸리의 지상부(LTi-A)에서 가장 많이 검출되었다. 이들 시료의 항산화 활성을 조사하기 위해서 DPPH와 ABTS 라디칼에 대한 소거 활성을 조사해 본 결과 DPPH 라디칼에 대해서는 비타민 C보다 소거 활성이 적은 것으로 나타났지만, ABTS 라디칼에 대해서는 비타민 C보다 더 좋은 소거 활성을 보였다. 이들 활성과 폴리페놀, 플라보노이드 화합물간의 상관관계에서는 폴리페놀만이 양의 상관관계를 보여 폴리페놀의 농도에 따라 라디칼 소거 활성이 증가하는 것을 관찰할 수 있었다. 하지만 플라보노이드 화합물과 라디칼 소거 활성 간에는 뚜렷한 상관관계를 볼 수 없어, 싸리속 식물에서는 플라보노이드 화합물보다는 폴리페놀성화합물이 항산화에 더욱 중요한 역할을 하는 것으로 판단할 수 있었다. 이러한 결과는 최근 각광을 받고 있는 천연 항산화제의 개발에 있어 싸리속 식물이 천연 항산화제로서 좋은 소재가 될 수 있음을 보여주고 있다.
