Abstract

Contents in polyphenol and vitamin C and their antioxidant activities during storage of Lycii folium prepared by different treatment methods were investigated. The antioxidant activity of extracts prepared from 80% MeOH was evaluated using DPPH radical scavenging and SOD-liked activities. Total phenolic acid contents were 1.34 mg/mL when dry, but extracts during 15-day storage after NaCl 0% treatment decreased. DPPH radical scavenging activity of extracts was 65.48% when dry and decreased during 15-day storage after dry and NaCl 0% treatment. SOD-liked activity was 98.63% in NaCl 0% during 15-day storage after dry. Contents of vitamin C decreased during 15-day storage after dry and NaCl 0% treatment. Consequently, our results indicate that Lycii folium prepared from dry treatment could be a promising biomaterial for the production of functional food for total phenolic acid and vitamin C.

본 연구는 구기엽(Lycii folium)의 조리방법을 달리한 저장기간에 따라 가공적성 및 구기엽의 생리활성, 유효성분 변화를 분석하기 위해서 구기엽 추출물을 제조하였다. 이 추출물들의 비타민 C 함량, 총 페놀화합물, 전자공여능 및 SOD 유사활성을 측정하였다. 조리방법을 달리한 저장기간에 따른 구기엽의 활성도는 총 페놀화합물 함량은 15일 경과 후 NaCl 0%에서 1.34 mg/mL로 유의적으로 높은 함량을 나타냈으나, 1일째 높은 페놀함량을 보였던 Dry군에서는 Control, NaCl 0%군에 비해 낮게 측정되었다. SOD유사활성은 모든 시료에서 85% 이상의 높은 활성이 측정되었으나, 총 페놀화합물과 마찬가지로 NaCl 0%에서 95.03%로 15일의 저장기간이 경과한 후에도 가장 높은 활성을 나타내었고, 전자공여능에서는 1일째 Dry 처리한 것이 전자공여능이 65.48%로 가장 높았고, 저장기간이 경과한 후에도 26.98%로 가장 높은 전자공여능을 보였다. NaCl 0%, NaCl 1%는 Control에 비해 10% 이상 높은 활성을 보였으나, 15일 경과 후에는 그 활성이 Control보다 낮게 측정되어, 시료를 건조하여 보관하였을 때 활성 감소가 다른 처리를 했을 때보다 적을 것이라 사료된다. 비타민 C 함량에서도 15일의 저장기간이 경과한 후 Dry 처리한 시료에서 1.70%로 가장 높은 값이 측정되었으며 저장기간에 따른 감소량 또한 다른 시료에 비해 적었다. 위 실험 결과 구기엽의 가공적성에 적합한 처리방법은 Dry, NaCl 0% 처리한 후 보관하는 것이 생리활성도와 유효성분 함량을 유지하는데 좋은 방법이라 사료된다.
