Abstract

The objective of this research was to evaluate the ability of water and 80% ethanol extracts from one hundred eight mulberry leaves (Morus alba L.) to influence the inhibitory activity of angiotensin converting enzyme (ACE) and xanthine oxidase (XOase). The total phenol contents were that water extracts of ten species (Kakjayongsan (Morus alba L.), Daejungsun (Morus alba L.) etc.) and 80% ethanol extracts of twenty three species (Waryoung (Morus alba L.), Hasusang (Morus alba L.) etc.) showed more than 15 mg/g. The inhibitory activity on angiotensin converting enzyme (ACE) were that ten species (YamanakkadakKaskke (Morus alba L.), Mijiro (Morus alba L.) etc.) showed 100% inhibition rate both of water extracts and 80% ethanol extracts. The rest, water extracts of thirty four species (Cheongilppong (Morus alba L.) etc.) and 80% ethanol extracts of thirty four species (Wonjukojo (Morus alba L.) etc.) showed inhibitory activity (above 90%) on ACE. Also, to search of xanthine oxidase (XOase) inhibition were that water extracts of five species (Cheongsipjosaeng (Morus alba L.), Suwon 3 (Morus alba L.) etc.) and 80% ethanol extracts of Jeokmok (Morus alba L.) showed inhibitory activity (above 50%) on XOase. This result revealed, strong biological activity in spite of has a little total phenol contents. These water and 80% ethanol extracts from mulberry leaves (Morus alba L.) are expected good candidate for development into anti-hypertentive and anti-gout sources.

생리활성을 갖는 새로운 기능성 물질을 개발할 목적으로 108종의 뽕잎을 이용하여 물과 80% 에탄올 추출물을 제조하고 이들의 Angiotensin converting enzyme(ACE) 활성억제효과 및 XOase(xanthine oxidase) 활성억제효과를 탐색하여 본 결과, 페놀함량이 물 추출물에서는 각자용산, 대정선 등 10종이, 80% 에탄올 추출물에서는 와룡, 하수상 등 23종이 15 mg/g 이상의 총 페놀함량을 나타내었으며, Angiotensin converting enzyme (ACE) 활성억제효과는 야마나까다까스께, 미지로 등 10종이 물 추출물 및 80% 에탄올 추출물에서 동시에 100%의 활성억제효과를 나타내었으며, 그 외 청일뽕 등 34종은 물 추출물에서, 원주고조 등 34종은 80% 에탄올 추출물에서 90% 이상의 활성억제효과를 나타내었다. 또한 XOase(xanthine oxidase) 활성억제효과는 물 추출물에서 청십조생, 수원상3호 등 5종이, 80% 에탄올 추출물에서 적목이 50% 이상의 활성억제효과를 나타내었으며, 그 외 수원뽕 등 27종은 물 추출물에서, 홍올뽕 등 21종은 80% 에탄올 추출물에서 약간씩의 효과를 나타내었다. 이상의 결과, g당 페놀함량이 적은 뽕잎이지만 높은 생리활성기능을 나타내는 여러 종의 뽕잎 물과 80% 에탄올 추출물들은 항고혈압 및 항관절염의 효과가 있는 기능성 식품소재로 활용할 수 있을 것으로 판단되었다.
