Objective To study the effect of Huanshaodan on lipofuscin content and structure stability of DNA in aging mice. Methods 36 aging Kunming mice (20months) and 12 young Kunming mice(2months) were randomly divided into four groups as following, aging control group, aging Huanshaodan group, aging vitamin E group and young control group. After feeding 10 weeks, the content of lipofuscin in brain tissue and the surplus rate of double-stranded DNA in liver tissue were detected with fluorescence spectrometry methods and spectrometry DNA alkali dege...
