| 摘 要： | 测定不同生长时期的6种萝卜苗(长春白萝卜苗、盛丰白萝卜苗、象牙白萝卜苗、德国特白萝卜苗、抚顺红萝卜苗及满堂红萝卜苗)正己烷提取物的总异硫氰酸盐和4-methylthio-3-butenyl isothiocyanate(MTBITC)含量,分别用FRAP法、ABTS法、抗超氧阴离子自由基(O-2·)和抗羟自由基(.OH)能力4种方法测定提取物的体外抗氧化性能。结果显示:萝卜苗中MTBITC含量占总异硫氰酸盐的80%以上;5～10d的萝卜苗中含有较高的MTBITC含量;同生长期的苗中,长春白萝卜苗、盛丰白萝卜苗、象牙白萝卜苗、德国特白萝卜苗的MTBITC含量比抚顺红萝卜苗和满堂红萝卜苗高。长春白萝卜苗、盛丰白萝卜苗、象牙白萝卜苗、德国特白萝卜苗4种萝卜苗的抗氧化性能与MTBITC含量呈正相关。而满堂红和抚顺红萝卜苗中MTBITC含量较低,但却表现出较强的抗氧化性能。

| Abstract: | The contents of total isothiocyanate contents and 4-methylthio-3-butenyl isothiocyanate(MTBITC) in n-hexane extracts of radish seedlings from 6 cultivars at different development stages were measured.Along with this,their antioxidant properties in vitro were evaluated using commercial FRAP,ABTS,superoxide anion free radical and hydroxyl free radical assay kits.The present study found that over 80% of total isothiocyanates in radish seedlings was MTBITC during 15 days of development.Radish seedlings aged 5-1... |
