Chemical Composition and Acaricidal Activity of Essential Oils fromCroton rhamnifolioidesPax and Hoffm. in Different Regions of a Caatinga Biome in Northeastern Brazil

Chemodiversity and Antibacterial Activity of the Essential Oil of Leaves of Croton argyrophyllus

“…[1] The Croton genus is the second largest in the Euphorbiaceae family with about 1.300 species distributed throughout northeastern Brazil [2 -4] and are popularly known as From a pharmacological perspective, some species of Croton are described to possess insecticidal, antifungal, antimicrobial, antioxidant properties. [1,5,7,8] In addition, previous studies involving pharmacological activities of Croton species show that antimicrobial activity has been widely investigated. [8 -17] This fact may be due to the progressive increase in resistance to antimicrobials in bacterial populations, mainly of hospital origin.…”

“…Many Croton species are essential oil producers whose chemical compositions are rich in monoterpenoids and sesquiterpenoids. [5,6] The essential oil composition and biological activity of Croton species such as C. cajucara, C. campestris, C. heliotropiifolius, C. hieronymi, C. malambo, C. rhamnifolioides, C. sonderianus, C. urucurana and C. zehntneri have been studied. [8,[10][11][12][13][14][15][16][17] These studies demonstrated a great diversity of chemical constituents in oils reported.…”

“…Several plants in the Euphorbiaceae family are part of the flora of the semiarid traditional medicine system [1] . The Croton genus is the second largest in the Euphorbiaceae family with about 1.300 species distributed throughout northeastern Brazil [2–4] and are popularly known as ‘velames’ or ‘marmeleiro’ [5] . These species are generally used in folk medicine as anti‐inflammatory, antioxidant, antiulcerogenic, antidiabetic, acetylcholinesterase and antimicrobial agents [1,6]…”

In addition, previous studies involving pharmacological activities of Croton species show that antimicrobial activity has been widely investigated [8–17] .…”

“…Essential oils obtained from aromatic plants are complex mixtures of volatile lipophilic compounds, characterized by strong odor and exhibit wide biological applications. Many Croton species are essential oil producers whose chemical compositions are rich in monoterpenoids and sesquiterpenoids [5,6] …”
