헛개나무 추출물을 이용하여 항산화, 아질산염소거 및 알콜분해 효과 등을 조사한 결과는 다음과 같다. 헛개나무 잎과 과병의 용매별 추출수율을 측정한 결과 잎은 물층, 과병에서는 메탄올층에서 각각 높게 나타났으며, 에탄올 추출물을 헥산, 클로로포름, 에틸아세테이트, 부탄올 및 물과 같은 용매를 이용하여 계통분획한 후 추출수율은 잎과 과병 모두 물분획층에서 높게 나타났다. 메탄올 에탄올, 헥산, 클로로포름 및 물 추출물을 이용하여 항산화 효과 및 아질

The present study was conducted to investigate antioxidant, nitrite scavenging and alcohol degradation effects of extracts from leaf and fruit stalk of Hovenia dulcis. Yields of various solvent extracts for Hovenia dulcis leaf and fruit stalk of were higher in water and methanol extract layer, respectively. Ethanol extracts of Hovenia dulcis leaf and fruit stalk of were fractionated with different solvents such as hexane, chloroform, ethyl acetate, butanol and water, yields of water fraction were highest. In the solvent extracts using methanol, ethanol, hexane, chloroform and water, ethanol extracts showed the most effective antioxidant and nitrite-scavenging effects. Ethanol extracts from Hovenia dulcis leaf and fruit stalk of were fractionated, the most natioxidant and nitrite-scavenging effects were ethyl acetate fraction. Alcohol degradation effects from different parts of Hovenia dulcis showed higher leaf and fruit stalk than xylem, branch and seed. Alcohol degradation effects from leaf and fruit stalk increased as time passed.
