Recently, I'm working on a project involving the use of n-butanol and ethyl acetate for phytochemical extraction. Ascending paper chromatography The procedure for ascending paper chromatography method is quite simple as compared to other methods of chromatography. Similarly, the solvent system composed of butanol:acetic acid:water was not further explored because of the need to neutralize the CPC fractions with . The polar solvent systems, such as BAW or sec -butanol-water, which are useful for peptides, proteins and other high MW entities, were not satisfactorily retained in the multilayer coil in the type J planetary centrifuges. Place just enough of this solution in a TLC jar to cover the jar for saturation of the chamber. Two typical two-phase solvent systems composed of 1-butanol-acetic acid-water (4.75:0.25:5, v/v) (BAW) and hexane-ethyl acetate-methanol-.1 M HCl (1:1:1:1, v/v) (HEMW) were used to separate the dipeptide and DNP-amino acid test samples, respectively.
