Abstract Myrciaria pilosa is a tree species of the Brazilian Caatinga biome. This paper is the first report on the chemical composition and the antimicrobial and antivirulence activities of essential oil extracted from its leaves. The oil was extracted by hydrodistillation. Chemical composition determined by GC–MS and CG–FID revealed 63 compounds; the sesquiterpenes guaiol (13.17%) and (E)-β-caryophyllene (11.26%) dominated. Antimicrobial activity against strains of Staphylococcus aureus was…

Lupane triterpenoids, antioxidant potential and antimicrobial activity of Myrciaria floribunda (H. West ex Willd.) O. Berg.

Screening for antimicrobial activity showed that the methanol extract was active against Staphylococcus aureus and Escherichia coli, but inactive against Candida albicans and Candida krusei, while 2α,6α,30-trihydroxybetulinic acid was inactive to all tested microorganisms.

The Anticancer, Antioxidant and Antimicrobial Properties of the Sesquiterpene β-Caryophyllene from the Essential Oil of Aquilaria crassna

β-caryophyllene is the active principle responsible for the selective anticancer and antimicrobial activities of A. crassnia and has great potential to be further developed as a promising chemotherapeutic agent against colorectal malignancies.

Antimicrobial constituents of peel and seeds of camu-camu (Myrciaria dubia)

The peel and seeds of camu-camu fruit could be utilized for therapeutic applications and the antimicrobial activities were similar to those of 2, and the minimum inhibitory concentrations were either similar to or lower than that of kanamycin.

Bioactivity of essential oils: a review on their interaction with food components

The scope of this review is a focus on interactions of EOs with proteins, carbohydrates, oils, NaCl, and pH, as well as a brief description on the different protocols to assess their bioactivity both under in vivo and in vitro conditions.

Constituents of the Essential Oil of Myrciaria tenella (DC.) O. Berg

Abstract The authors obtained the essential oil of the leaves and thin branches of Myrciaria tenella via hydrodistillation and analyzed by GC and GC/MS. The oil of M. tenella was found to be rich in

Volatile Constituents of Camu-camu (Myrciaria dubia (HBK) McVaugh) Leaves

Abstract The chemical composition of the leaf oil of camu-camu (Myrciaria dubia (HBK) McVaugh) was studied by GC and GC/MS. One hundred and fifteen components of the oil were identified, of which
