While this method is optimized for acylsugar extraction, it can be tweaked to use for other metabolites on the leaf surface.Below is a literature that is highly useful for acyslugar identification:Comparative structural profiling of trichome specialized metabolites in tomato (Solanum lycopersicum) and S. habrochaites: acylsugar profiles revealed by UHPLC/MS and NMR (doi: https://doi.org/10.1007/s11306-013-0585-y)Below is a literature that is highly useful for acyslugar identification:Comparative structural profiling of trichome specialized metabolites in tomato (Solanum lycopersicum) and S. habrochaites: acylsugar profiles revealed by UHPLC/MS and NMR (doi: https://doi.org/10.1007/s11306-013-0585-y)
