摘要
对北五味子乙素进行抗氧化及体外抑菌实验。结果表明:北五味子乙素对自由基的清除效果明显,其中对.OH清除作用大于相同浓度的VC,其半数清除浓度为0.2mg.mL-1;对O2-.清除作用小于VC,其半数清除浓度为0.24mg.mL-1。北五味子乙素提取液对金黄色葡萄球菌、白色念珠菌、沙门氏菌、大肠杆菌、枯草芽孢杆菌均有一定的抑制作用,其中对白色念珠菌和金黄色葡萄球菌的抑制作用最强,最低抑菌浓度为0.25mg.mL-1,对根霉、黑曲霉、南阳酵母无明显抑菌活性。
Antioxidation and antimicrobial activities of the schisandrin B extraction from Schisandra chinensis（Turcz.） were studied.The results showed that schisandrin B had effective scavenging effect on the hydroxyl radical（ ·OH） and the super oxideanion radical （O2-·）. Scavenging effect of · OH（ IC50 = 0.2mg·mL-1）was higher than that of the same concentration of Vc. Scavenging effect of O2-· （IC50 = 0.24mg·mL-1） was less than that of Vc. Schisandrin B had a certain activity against Staphylococcus aureus, Candida albicans, Salmonella, Ecoli, Bacillus subtilis.The activity against Candida albicans and Staphylococcus aureus was the strongest with minimum inhibitory concentration of 0.25 mg·mL-1. There was no activity on Rhizopus,Aspergillus niger and Nanyang yeast.
