초록

맥문동을 열수 추출하여 전자공여능, 항산화력 및 항균력을 시험한 결과는 다음과 같다. 1. 전자공여능은 대조구인 BHA가 85 Vit C가 92, 녹차추출물(GT) 1 Brix%는 88, 반건조 맥문동 추출물(MDL) 10 Brix%는 65, 건조 맥문동 추출물(DL) 3 Brix%는 79를 나타내었다. 2. 지질과산화물 생성 억제 효과는 녹차추출물(GT) > 건조맥문동 추출물(DL) > 반건조 맥문동 추출물(MDL) 순으로 녹차추출물(GT)이 가장 높은 것으로 나타났다. 3. S. aureus에 대한 각 시료의 항균력은 BHA > 녹차추출물(GT) 순이며, 반건조 맥문동 추출물(MDL)과 건조 맥문동 추출물(DL)은 나타나지 않았다. E. coli에 대한 각 시료의 항균력 또한 BHA > 녹차추출물(GT) 순이며, 반건조 맥문동 추출물(MDL)과 건조 맥문동 추출물(DL)은 나타나지 않았다. 4. 맥문동 열수추출물의 전자공여능과 지질과산화물 생성 억제 효과는 반건조추출물(MDL)보다 건조추출물(DL)이 우수한 것으로 나타났으며, 항균력에서는 S. aureus와 E. coli에 대하여 항균력이 나타나지 않은 것으로 나타났다.

Antioxidant and antimicrobial efficiency were investigated for: i) water extract of green tea(Camellia sinensis), ii) water extract of middle drying megmoondong(Liriope platyphylla Wang et Tang) and iii) water extract of drying megmoondong. The electron donating ability of the green tea(Camellia sinensis) and drying megmoondong(Liriope platyphylla Wang et Tang) extract were 88 and 79, respectively, while that of the middle drying megmoondong extract showed low levels. The relative inhibitory abilities against lipid peroxidase were: green tea(Camellia sinensis) extract > drying megmoondong(Liriope platyphylla Wang et Tang) extract > middle drying megmoondong extract. The green tea(Camellia sinensis) extract showed the strongest antimicrobial effect against Staphylococcus aureus. The middle drying(Liriope platyphylla Wang et Tang) and drying megmoondong extracts showed no antimicrobial effect against Staphylococcus aureus. The green tea(Camellia sinensis) extract had the strongest antimicrobial effect against Escherichia coli. The middle drying megmoondong(Liriope platyphylla Wang et Tang) and drying megmoondong extracts showed no antimicrobial effect against Escherichia coli.
