Biplot of the first two components obtained by PCA performed with data obtained from all assayed parameters. Arrows indicate the eigenvectors for assayed parameters, and dots represent honey samples (1–4 = Kakamega, 5–8 = Coast, 9–12 = Mwingi, 13–16 Mt. Kenya, 17 = Manuka5+). abnp, antibacterial (nonperoxide activity); abw, antibacterial (whole activity); ao, antioxidant (1/IC₅₀); el_cond, electrical conductivity; nb, H₂O₂ contribution; TFC, total flavonoid content; TPC, total phenolic content.
