Abstract

To evaluate the physiological properties of 22 varieties of legumes, antioxidative activity, antimutagenicity against Mitomycin C, genotoxicity, and mutagenicity were tested. Ethanolic extracts of legumes had significant antioxidative activities in the tests of electron-donating ability to DPPH radical, hydroxy radical-scavenging activity, and inhibitory effect on lipid auto-oxidation model system. Soy sprout bean (green), mung bean, and small black bean (green) had excitatory effects on the growth of E. coli PQ 37 cell. Black bean and green soy bean had inhibitory effects on the mutagenicities of the cells. Rice bean, pea, mung bean, and bonavista bean showed antimutagenic activities against chemical mutagen, Mitomycin C. Thus, rice bean and mung bean were found to be appropriate auxiliary ingredients of rice cake and rice processing food for the promotion of health and augmentation of rice and legume consumptions.

시판되고 있는 두류 22 종류의 70% 에탄올 추출물을 제조하여, 이들의 항산화 활성, 화학적 변이원 mitomycin C에 대한 항변이원성, 세포독성, 변이원성 등을 포함하는 생리활성 효과를 비교 검정하였다. DPPH radical에 대한 전자공여능, hydroxy radical 소거능 및 지질 자동산화 억제효과 등은 모든 두류 품종이 거의 유사한 효과를 나타내었다. 예팔, 완두, 녹두, 백편두 등은 변이원 mitomycin C에 대해 유의할만한 수준의 항변이원성을 보였으며, 녹색나물콩, 녹두, 속피리 등은 지시 세포의 성장을 촉진하는 효과가 있었고, 속청과 청태는 변이원성을 억제하는 특성이 있었다. 백편두는 세포 성장과 돌연변이 유발 모두를 억제하는 것으로 나타나 추출물 자체가 독성을 가질 수도 있을 것으로 생각되었다. 결과적으로 본 연구의 목적이었던 기능성 밥 및 떡 제조를 위한 부재료로서의 두류 이용을 위해서는 예팥, 녹두 등을 이용하는 것이 바람직하리라고 생각된다.
