Hyperspectral data are commonly used for the fast and inexpensive quantification of plant constituent estimation quality control as well in research development applications. Based on chemical analysis, different models dihydroisocoumarins (DHCs), namely hydrangenol (HG) phyllodulcin (PD), were built using a partial least squares regression (PLSR). While HG is common Hydrangea macrophylla, PD o...
