摘要
采用300Gy的60Coγ射线诱变马棘干种子,成功选育了高黄酮含量的突变体MJ-HF1。各个组织中,MJ-HF1的黄酮含量均高于野生型,尤以种子和叶片中的黄酮含量为高,分别是野生型的5.89倍和1.46倍。抗氧化试验表明,马棘突变系黄酮提取物给药30d后能降低老龄小鼠脂质过氧化物代谢产物丙二醛(Malondialdehyde,MDA)的含量和升高老龄小鼠超氧化物歧化酶(Superoxide dismutasv,SOD)的活力。
Mutant high in flavonoid was successfully developed after the dry seeds of Indigofera pseudotinctoria Mats were irradiated by 300Gy 60Co gamma rays.The contents of flavonoid in different tissues of mutant line MJ-HF1 were all higher than that of the wild type,especially in the seeds and leaves,which was 5.89 and 1.46 times of the wild type.Anti-oxidation testing showed that the flavonoid exacts from MJ-HF1 could decrease the contents of malondialdehyde（MDA） and increase the activities of superoxide dismutase（SOD） in the aged white mice in a 30-day feeding test.
