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代谢物未大量合成的青麻材料，采用简化CTAB法提取青麻DNA，可以获得高纯度、高产量的DNA。

The oil absorption value test clarifies that the surface oleophilic character of MnCO3 received on the condition that butanol, CTAB bulk ratio of 1:4 have been well improved.

测定结果表明：经正丁醇与CTAB体积比1:4体系得到的碳酸锰粉表面亲性能得到明显改善。
