Table 1. . Main antibacterial families (at least 5% of genera antibacterial except Fabaceae; see discussion), their known mechanisms of action, and active phytochemicals involved based on the references listed in Supplementary Table 1.

Family	Known mechanism of action	Primary active phytochemicals
Combretaceae	Quorum sensing/biofilm inhibitor	Flavonoids, e.g., catechin, naringenin; ellagic acid, ellagic acid derivatives, ellagitannins
Cupressaceae	Quorum sensing/biofilm inhibitor	Monoterpenes, e.g., limonene, α-pinene, δ-3-carene, α-terpinolene, camphor; sesquiterpenes, e.g., cedrol; polyphenols
Fabaceae	Inhibits cell wall and/or membrane	Phenolics, flavonoids
Lamiaceae	Inhibits cell wall and/or membrane	Terpenes/terpenoids, e.g., 1,8-cineole, pulegone, thymol, carvacrol, linalool, estragole, citral; carnosic acid; dihydroajugapitin; flavonoids, e.g., baicalin
Lauraceae	Inhibits cell wall and/or membrane	Aldehydes (e.g., cinnamaldehyde), aromatic alcohols (eugenol, benzyl alcohol); terpenoids (citral, citronellal, 1,8-cineole); endiandric acid and derivatives
Meliaceae	Mechanism unknown	Triterpenoid, e.g., limonoids
Myrtaceae	Quorum sensing/biofilm inhibitor	Monoterpenes, e.g., 1,8-cineole, α-pinene, α-terpineol; eugenol; flavonoids, e.g., quercetin
