velvetleaf

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.

本研究利用黄酮等次生谢物未大量合成的青麻材料，采用简化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.

摘要青麻成熟组织中酚类、黄酮类等次生谢物较多，要从中提取出高纯度的DNA比较困难。
