Antibacterial activity and chemical composition of the essential oil of Croton heliotropiifolius Kunth from Amargosa, Bahia, Brazil

Characterisation of Staphylococcus aureus strains from milk and goat cheese and evaluation of their inhibition by gallic acid, nisin and velame of the Brazilian caatinga

“…Velame is widely used by local communities in Brazil, especially for the treatment of gastrointestinal disorders and general infections involving fever (Brito et al ; Silva et al ). Consistent with our results, Araújo et al () reported the antimicrobial activity of C. heliotropiifolius against S. aureus and stated that EO has potential applications against multidrug‐resistant strains of Staphylococcus spp. The EO of C. heliotropiifolius has high percentages of sesquiterpenes, particularly (E)‐β‐caryophyllene, demonstrating strong antimicrobial and antioxidant activity (Alencar filho et al ; Araújo et al ; Brito et al ).…”

The antibacterial activity of sesquiterpenes is related to rupture of cell microtubules, decreases in fatty acids and disturbances in the cell membrane that lead to membrane potential alteration, ion loss, proton pump collapse and ATP depletion (Huang et al ).…”

“…Velame is used by the local population as a herbal remedy (tea) (Alencar Filho et al ) and as a preservative in goat meat products (Rigo ). Its EO is recognised as a promising alternative source for antimicrobial agents and natural antioxidants (Araújo et al ; Brito et al ). According to Araújo et al (), the EO of the aerial part of C. heliotropiifolius is effective against multidrug‐resistant S. aureus .…”

According to Araújo et al (), the EO of the aerial part of C. heliotropiifolius is effective against multidrug‐resistant S. aureus . In addition, C. heliotropiifolius EO contains bioactive compounds that can contribute to increase the nutritional value of the food (Brito et al ).…”

Phytotoxic and nematicide evaluation of Croton ehrenbergii (Euphorbiaceae)

“…C. ehrenbergii is a shrub with white flowers that grows up to 1.5 m in height. Croton species have therapeutic uses as anti‐inflammatory, anti‐ulcer, anti‐tumor, antioxidant and cytotoxic agents in addition to insecticidal, antimalarial, larvicidal, antimicrobial, molluscicidal and anthelminthic activities . For their protection, plants produce secondary metabolites that have been subject to research due to their influence on the growth and distribution of other plants, as well as the life cycle of pathogens in nature .…”
