| 摘 要： | 为了探讨山嵛菜植物各部分的抗氧化与抑制酪氨酸酶能力,将新鲜山嵛菜的叶、叶柄、块茎、根须等,用20%乙醇水溶液提取后,分别检测各部分的总抗氧化能力、灭活超氧阴离子能力和抑制酪氨酸酶能力。结果表明,总抗氧化能力以山嵛菜叶最强(68.4单位,0.1 g/mL);灭活超氧阴离子能力也是山嵛菜叶最强(IC50值0.7mg/mL);抑制酪氨酸酶能力以山嵛菜块茎、根须最强(IC50值0.3或0.4 mg/mL)。上述资料为进一步开发利用山嵛菜提供了依据。

| Abstract: | To explore the activity of oxidation resistance and inhibiting the tyrosinase in Wasabi,it was respectively detected for total oxidation resistance,the activity of anti-superoxide anion and inhibiting the tyrosinase activity after 20% alcohol extraction of verdure Wasabi in leaf,leaf stalk,stem tuber and rhizoid.According to the results,total oxidation resistance indicated as the strongest in leaf(68.4 U,0.1 g/mL),the activity of anti-superoxide anion is also the strongest in leaf(IC50= 0.7 mg/mL) and the tyrosinase inhibiting activity is the strongest in stem tuber and rhizoid(IC50= 0.3 or 0.4 mg/mL).Our study provided the evidence for further exploiting and updating Wasabi. |
