the essential oil of peucedanum ru t h e n i c u m fruits, obtained by hydrodistillation, was analyzed by gas chromatography and gas chromatography mass spectrometry. among the 31 identified constituents accounting for 83.9% of the total oil, the major components were 1,8-cineole (11.15%), camphor (5.86%), z-carveol (6.88%), l-carvone (5.61%), 8,9-dehydroisolongifolene (11.35%), caryophyllene o...

Alpinia monopleura is an endemic plant which widespread and abundant in Sulawesi. Nevertheless, previous studies have not studied the chemical compound biological activity. This study describes compounds antibacterial antioxidant properties of essential oils isolated from A. monopleura. The oil was obtained by hydro distillation method interpreted GCMS. Antibacterial were determined agar diffus...

bark extract of pinus pinaster contains numerous phenolic compounds such as catechins, taxifolin, and phenolic acids. these compounds have received considerable attentions because of their anti-inflammatory, antimutagenic, anticarcinogenic, antimetastatic and high antioxidant activities. although p. pinaster bark has been intensely investigated in the past; there is comparably less information ...

BACKGROUND Periodontal disease is a highly prevalent illness that affects many dogs, reaching up to 85 % prevalence in individuals over the age of 4 years. Currently the drug of choice for combating the formation of dental plaque in these animals, the etiologic agent of the disease, is chlorhexidine, which has several side effects reported. Thus, surveys are conducted throughout the world in or...

Aedes aegypti is responsible for the transmission of dengue, a disease that infects millions of people each year. Although essential oils are well recognized as sources of compounds with repellent and larvicidal activities against the dengue mosquito, much less is known about their oviposition deterrent effects. Commiphora leptophloeos, a tree native to South America, has important pharmacologi...

Xylopia laevigata, popularly known as "meiú" and "pindaíba", is a medicinal plant used in the folk medicine of the Brazilian Northeast for several purposes. The chemical constituents of the essential oil from leaves of X. laevigata, collected from wild plants growing at three different sites of the remaining Atlantic forest in Sergipe State (Brazilian Northeast), were analyzed by GC/FID and GC/...

This study investigates the variations in chemical profiles and biological activities (antioxidant cytotoxic) of Eplingiella fruticosa from state Sergipe, an endemic species Northeast region Brazil. The essential oils were extracted six populations by hydrodistillation analyzed GC/MS-FID. Cluster analysis was performed with data constituents oils, then a dissimilarity matrix, based on Euclidean...
