This is a costly and time-consuming process in which much of the initialpurity of the GeCl4 is lost.
这是昂贵费时的工艺,其中GeCl4的初始纯度被大大损失。

Mature leaves contain more initial metabolites, such as phenols, polysaccharides, lipids and other substances, and the DNA contained in a relatively small, so it is difficult to extract a low purity.
