Abstract

This study was carried out to investigate biological and antioxidative activities on the fruit of bogbunja (Rubus coreanus Miquel). Total contents of phenolic compounds contents in cultivars ripened fruit and immatured wild-type fruit were 222 and 190mg/g, respectively, Polysaccharide contents of immatured wild-type fruit were the highest value of 320U. For EDA analysis, immatured wild-type fruit showed over 95% in 100$\mu\textrm{g}$/mL of sample concentration, which is the the most effective. Levels of SOD-like activities in immatured and cultivar ripened fruits were 81% and 77%, respectively, For the inhibitory effect on lipid peroxidation, all of bogbunja prepared were similar with those of $\alpha$-tocopherol as control. The inhibition of ACE activities on the water extracts of bogbunja fruit showed over 98%, especially, in immature wild-type and cultivar bogbunja.

복분자 열매의 생리활성 효과를 알아보기 위하여 재배복분자와 야생복분자를 이용하여 실험을 수행하였다. 총페놀성 화합물 함량은 재배복분자 완숙과와 야생복분자 미숙과에서 각각 222, 190mg/g 이었고, 다당체 함량은 야생 북분자 미숙과가 320 unit로 가장 높은 함량을 나타내었다. 복분자 열매의 전자공여능은 야생복분자 미숙과가 100 $\mu\textrm{g}$/mL 농도에서 95% 이상으로 높은 활성을 보여 미숙과가 완숙과에 비해 높은 전자공여능을 갖는 것으로 나타났다. SOD 유사활성은 야생복분자 미숙과가 81%, 재배복분자 완숙과가 77%를 나타내어, 총페놀성 화합물과 같은 추세를 보였으며, 과산화지질 형성억제능은 모든 처리구에서 대조구인 $\alpha$-tocopherol과 같은 억제수준을 나타내었다 복분자 열매의 고혈압 완화효과로써 ACE 활성 저해율은 야생복분자 미숙과와 재배복분자 완숙과가 추출농도 1% 범위에서 98% 이상의 높은 ACE 활성 저해율을 보였다.
