Identified polyphenolics showing significant differences in LC-MS intensity with respect to antimicrobial activity classification of all 87 Rhododendron species (remaining 282 identified compounds are provided in Figure S4). 17 species are denoted as antimicrobial active (orange), i.e., the radius of the agar diffusion assay is ≥0.6 cm, and, thus, 70 species are characterized as antimicrobial inactive (violet).
