Abstract
Antioxidative effects of crude ethanol extract of the Rhus javanica L. and its fractionates with various synergists on the oxidation of palm oil, lard and soybean oil were compared with induction period(IP) using a Rancimat test. Addition of 200 ppm of the crude extract with phosphoric acid to palm oil extended IP 2.89 times as much as that of control and ethyl acetate fractionate extended IP 4.18 times at the same condition. To lard, 600 ppm of chloroform fraction with 200 ppm of
항산화 효과가 화인된 붉나무 에탄올 조추출물 및 용매별 분획물에 ascorbic acid, citric acid, tocopherol, phosphoric acid, lecithin, phytic acid 등을 혼합, 괌유, 돈지, 대두유에 넣어 산화방지 효과를 Rancimat test에 의하여 비교하였다. 팜유에 붉나무 조추출물과 인산을 각각 200ppm 첨가시, 유도기간은 무첨가구에 비해 2.89배 증가했으며. 붉나무 추출물의 ethyl acetate 분획물 200ppm과 인산 200ppm을 첨가했을 때 유도기간은 4.18배, 같은 조건에서 chloroform 분획물은 2.48배의 유도기간 연장 효과가 있었다. 돈지의 경우 chloroform 분획물 600 ppm과
