Physiological Functionality in Geumsan Perilla Leaves from Greenhouse and Field Cultivation

온실재배와 노지재배한 금산 깻잎의 생리기능성

  • Published : 2003.10.01

Abstract

Perilla leaves cultivated in greenhouses (Jan., May) and in the fields (Aug.) of Geumsan province were investigated for their extract yields and physiological functionalities. The yield was highest in 30% ethanol extracts of the August perilla leaves. The highest fibrinolytic activity (8.2 U) was observed in 30% ethanol extracts of the May perilla leaves, while the HMG-CoA reductase inhibition level, which is related to the inhibition of cholesterol biosynthesis, was 83% in water extracts of the August perilla leaves. Anti-hypertensive ACE inhibitory activity was 64.5% in the water extracts of the January perilla leaves, and antioxidative electron donating ability was the highest (69%) in 30% ethanol extracts of the August perilla leaves. Elastase inhibitory activity, which is related to the inhibition of skin aging, was highest (47.5%) in 30% ethanol extracts of the May perilla leaves. However, SOD-like activity, nitrite scavenging activity, and tyrosinase inhibitory activity were not detected were very weak in all samples.

깻잎 중의 각종 성인병 관련 생리기능성을 탐색하여 고부가가치의 건강식품을 개발하고자 먼저 깻잎의 주산지중의 한곳인 금산에서 1월, 5월 온실재배한 깻잎들과 8월 노지재배한 깻잎의 추출물 수율을 조사하였다. 8월 노지에서 재배한 깻잎의 에탄올 추출물 수율이 29%로 제일 높았고, 1월과 5월 온실재배 깻잎보다는 8월 노지재배 깻잎의 추출물 수율이 더 높았다. 물과 30% 에탄올 추출물에 대한 생리기능으로 혈전용해활성은 5월 온실재배 깻잎의 에탄올 추출물이 8.2U로 제일 높았고 고지혈증 예방에 관련된 HMG-CoA reductase 저해활성은 8월 노지재배의 물 추출물에서 83%의 높은 활성을 보였다. 항고혈압활성을 나타내는 안지오텐신 전환효소(ACE) 저해활성은 1월 온실재배 깻잎의 물 추출물에서 64.5%의 높은 활성을 보였다. 항산화활성은 물 추출물 보다는 대체로 30% 에탄올 추출물에서 높았고, 특히 8월 노지재배 깻잎의 에탄올 추출물에서 69%를 보였다. Elastase 저해활성은 5월 온실재배 깻잎의 30% 에탄올 추출물에서 47.5%의 활성을 보였고 혈전용해활성과 아질산염 제거활성, SOD-유사활성과 tyrosinase 저해활성 등은 모든 깻잎 추출물에서 없거나 매우 미약하였다.
