“…Although the active antimicrobial agents in these natural sources were not isolated before use, the activity of the extracts is a result of the inherent phytochemicals, which may be working together in synergy. e antimicrobial, antioxidant, and cytotoxic properties of the extracts have been attributed to phytochemicals such as citral, aspilactonol B, and 8-methyl-6-prenylquercetin (found in C. citratus) [178], fukugetin and fukugiside (found in G. brasiliensis) [179], carnosic acid, carnosol, and rosmanol (found in L. meyenii) [180], and morin, myricetin, and rhamnetin (found in Cranberry) [181], while a wide range of phytochemicals such as alkaloids, cyanogenic glycosides, flavonoids, phenols, saponins, and tannins was found in P. Americana seed extract [182]. In the same vein, the ethyl acetate fraction of S. orientalis contained compounds such as 16β, 17, 18-trihydroxy-ent-kauran-19-oic acid, 16β-hydro-ent-kauran-17, 19-dioic acid, 16α, 17-dihydroxy-ent-kauran-19-oic acid, and 17, 18-dihydroxy-ent-kauran-19-oic acid [183], germacrene D, (E)-caryophyllene, α-guaiene, and β-elemene (found in H. cangaceira) [189], caryophyllene oxide, 6,9guaiadiene, and cis-calamenene (found in V. gardneriana) [190], elemicin, methyl eugenol, and 4-allyl-2,6-dimethoxyphenol (found in D. pinnata) [191], and limonene (found in citrus oil) [192].…”
