<div>Thin-layer chromatography will be used to visually examine individual compounds in a quick and easy manner, using general stains (vanillin) and more specific stains for compounds such as alkaloids (iodine stain). This will identify the crude extracts to pursue and will also identify certain fractions to pursue and give an idea of the purity of a fraction or sample. TLC plates can easily be examined under long or short UV light to identify compounds with aromatic or double bond components.
