Siparuna guianensis Essential Oil Antitumoral Activity on Ehrlich Model and Its Effect on Oxidative Stress.

This work aims to evaluate the chemical composition, in vitro antioxidant capacity, and in vivo antitumoral activity of S. guianensis essential oil against Ehrlich's ascitic carcinoma and the effects on oxidative stress. The animals (Mus musculus) received a daily dose of S.

Chemometrics of the Composition and Antioxidant Capacity of Essential Oils from Brazil.

(Pohl) ex Benth is used in traditional medicine as an analgesic to treat general pain. Six samples (Hc-1 to Hc-6) were collected in Pará state, Brazil. The leaf essential oils were obtained by hydrodistillation, and GC-MS and GC-FID were used to analyze their chemical compositions.

Variability in the Chemical Composition of (G. Mey) DC. Essential Oils Growing in the Brazilian Amazon.

(G. Mey) DC. is known as "insulin plant" because local communities use the infusions of various organs empirically to treat diabetes.

Chemical Composition and Variability of the Volatile Components of Species Growing in the Amazon Region.

(Myrtaceae) species have been well investigated due to their chemical and biological relevance. The present work aimed to carry out the chemotaxonomic study of essential oils of the species , , and , sampled in the Brazilian Amazon and compare them with the volatile compositions from other species reported to Brazil and Colombia. The leaves of six specimens were collected (PA, Brazil) during the dry season, and their chemical compositions were analyzed by gas chromatography-mass spectrometer (GC-MS) and gas chromatography-flame ionization detector (GC-FID).
