Phytochemistry & Biodiscovery

Identity and purity of the starting material are prerequisites for safety and efficacy of herbal medicinal products. For unambiguous identification and quality assessment of herbal drugs and their preparations we use robust, quick and reliable methods like HPTLC, microscopy, UV/VIS-spectrophotometry, GC, UPLC and FTIR.Sophisticated combinations of high performance separation techniques with specific high-end detectors (e.g. GC-MS, UPLC-DAD-MSn, SFC-MS, UPLC-MS/MS) allow the identification and exact quantification of very small amounts of compounds, even present in complex matrices or mixtures like plant extracts, tissues or body fluids.
