A semi-purified crude extract(SP) was tested against five known phenolic compounds, namely: (1) Quercetin, (2) Rutin, (3) Gallic acid, (4) Catechin, and (5) Ellagic acid. Answer the following questions: Based on the developed chromatogram, what can you infer about the semi-purified crude extract? Based on the developed chromatogram and your knowledge about TLC, what can you say about compounds 1 and 2? Is TLC the most accurate and reliable chromatographic technique used in analytical chemistry? If yes, why? If not, what is a more accurate and reliable chromatographic technique than TLC?
