1.Through the simple method of CTAB, total DNA of velvetleaf was extracted from sprouts of velvetleaf in which there was a little secondary metabolites.

1.本研究酮等次生代谢物未大量合的青麻幼芽为材料，采化CTAB法提取青麻总DNA，可以获得高纯度、高产量的DNA。

2.Because the mature tissue of velvetleaf contains lots of secondary metabolites such as alkaloid and phenolic, it is difficult to obtain high purity DNA from mature tissue of velvetleaf.

2.摘要青麻织中酚类、酮类等次生代谢物较多，要从中提取出高纯度的DNA比较困难。
