Idetification and Quantification of Salvinorin A
"Typical TLC analyses carried out during the extraction of S. divinorum samples and purification by column chromatograpgy used 20 cm x 20 cm silica gel G-F245 plates. Plates were developed with a mixture of hexane:EtOAc 1:1 and salvinorin spots visualized using either the vanillin-sulfuric acid or anisaldehyde sulfuric acid spray reagent, followed by heating in an oven at 100° C for 10 minutes."
"Authentic salvinorin A...appeared as a violet-blue spot with an Rf of 0.45 - 0.53"
