(Petri dishes vs. soil) is very low. Thereby, it has to be taken into account that different extracts have different chemical compounds, depending on the polarity of the solvent. In addition, they can be subject to natural fluctuations, depending on various biotic and abiotic factors during ...
In addition, the use of a triphasic solvent system composed of n-heptane, MtBE, CH3CN, and water was already reported as an efficient method to fractionate natural compounds from barks in a wide range of polarity [13]. The experiment lasted approximately two hours while UV (Figure 1) and ...
