Abstract

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of ninety four plant extracts on ACE. The extracts were prepared by water and refluxing with 70% and 100% methanol. Among the extracts, two plant extracts such as Cassia tora, Persicaria cochinchinensis Kitagawa showed more than 60% inhibitory activities, and Foeniculum vulgare Gaertner, Scutellaria baicalensis Georgl, Caragana sinica (Buchoz) Rehder, Inula britannica var. chinensis showed $45.2{\sim}49.7%$ inhibitory activities. Twenty eight plant extracts such as Hemerocallis fulva L, Camptotheca acuminata Decne, Inula britannica var. chinensis, Xanthium strumarium, Polygonatum odoratum, Phellodendron amurense Rupr, Coix lachryma-jobi var. mayuen, Prunus ansu, Hibiscus mutabilis L, Thchosanthes kirilowii, Helianthus annuus, Juglans sinensis showed $30.3{\sim}39.7%$ Inhibitory activities. These results suggest that plant extracts which contain high ACE inhibitory activities may be useful as anti-hypertension agents and to the treatment of hypertension.

94종 식물자원을 대상으로 혈압상승을 주도하는 효소인 angiotensin converting enzyme의 저해활성을 검색하였다. 그 결과 추출물의 농도가 1mg에서 60%이상의 높은 ACE 억제활성을 보인 식물은 털여뀌 (81.6%), 결명자 (64.2%) 등의 2종이었으며, 40%이상의 ACE 억제 활성을 보인 식물은 금불초(49.7%), 골담초(49.4%), 황금(48.1%), 회향(45.2%)등 4종으로 ACE 억제활성이 비교적 높게 나타났다. 또한 $30{\sim}40%$의 ACE 억제활성을 보인 식물은 까마귀머루(35.5%), 부용(32.3%), 삼립국화(32.6%), 산비장이(33.2%), 산사나무(33.9%), 율무(34.8%), 제비꽃(37.1%), 진득찰(37.1%), 짚신나무(36.1%), 참죽나무(39.7%), 창질경이(33.5%), 컴프리(33.9%), 털냉초(39.7%), 하눌타리(39.4%), 해바라기(34.2%), 호두나무(39.4%), 회양목(30.6%), 희수(35.8%), 금불초(36.8%), 도꼬마리(34.8%), 두충나무(30.3%), 둥글레(35.2%), 방풍(33.5%), 산옥잠화(34.8%), 살구나무(39%), 섬오갈피(38.4%), 원추리(39.7%), 지모(31.9%)등 28종이었다. 그 외 흰제비꽃, 황해쑥, 쥐방울덩굴, 자귀나무, 일당귀, 오크라, 애기기린초, 순비기나무, 쇠뜨기 , 석창포, 석결명, 사위질방, 산수유나무, 부추, 뽕나무, 봉선화, 보리수나무, 큰꽃삽주, 범부채, 벌등골나무, 모감주, 동과, 도라지, 땃두릅, 도꼬마리, 산옥잠화, 방풍, 둥글레, 닭의장풀, 닥나무, 노루오줌, 가시오갈피, 개오동, 귀릉나무, 꽈리, 까실쑥부쟁, 골담초, 고삼, 고비고사리, 개발나물, 결명자, 형개, 향유, 한련초, 파고지, 초과, 지골피, 마두령, 금앵자, 곽향 등 50여 종의 추출물은 $10{\sim}30%$의 낮은 ACE 억제활성을 보였다. 앞으로 ACE 억제활성이 높은 식물자원의 유효성분에 대한 물질 확인과 동물모델을 이용한 효능검증에 대하여 더 많은 연구가 있어야 할 것으로 사료된다.
