Chemical composition and antibacterial activities of Rhus tripartita essential oils from Algeria

Abstract. Benlembarek K, Lograda T, Ramdani M, Figueredo G, Chalard P. 2021. Chemical composition and antibacterial activities of Rhus tripartita essential oils from Algeria. Biodiversitas 22: 482-492. The yield in Algeria is low with an average 0.16 ± 0.017. chemical the was determined by GC-GC / MS analysis. Seventy-eight compounds were identified 92.3 26.4% total oil. α-pinene (58.72 14.45%), Δ3-carene (5.21 6.89%), caryophyllene-Z (4.55 4.68%) β-pinene (3.07 1 85%) are major components R. populations. results reveal a notable difference between male female this species composed four chemotypes, Δ3-carene, α-pinene; limonene chemotype characterizes populations Tamanrasset Boussaada. - M’sila Mergueb. population characterized Δ-cadinene chemotype. remaining show evaluation reveals that Staphylococcus aureus, Escherichia coli, Proteus mirabilis Pseudomonas aeruginosa not sensitive to tripartita. In contrast, Enterococcus faecalis most oils.
