Composition and antifungal activity of essential oils from Piper aduncum, Piper arboreum and Piper tuberculatum

Antimicrobial activity of Piper arboreum and Piper tuberculatum (Piperaceae) against opportunistic yeasts

Essential Oils from Four Piper Species

ÐThe essential oils from Piper capense, P. nigrum, P. guineense and P. umbellatum from S. Tome e Prõ ncipe were investigated for the ®rst time. They were analysed by GC, GC-mass spectrometry and C NMR. Monoterpene hydrocarbons were the main group of constituents in three of the samples (P. capense, P. nigrum and P. umbellatum), whereas for the other species (P. guineense) phenylpropanoid deri...

EXTRACTION, CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OILS OF PIPILONGO (Piper tuberculatum) USING SUPERCRITICAL CARBON DIOXIDE

Essential oils from pipilongo seeds (Piper tuberculatum) was extracted using supercritical carbon dioxide. The extraction was performed as a function of particle size of the grinded seeds. The highest yield (2,812%) was obtained with the smallest particle size. The chemical composition analysis of the oil by GC-MS led to identify 15 compounds, some of which are β-elemene, caryophyllene, β-farne...

Antiparasitic Activity and Essential Oil Chemical Analysis of the Piper Tuberculatum Jacq Fruit

With the increase of neglected diseases such as leishmaniasis and Chagas disease, there wasa need for the search for new therapeutic alternatives that reduce the harm caused by medicineavailable for treatment. Thus, this study was performed to investigate the antiparasitic activityof the essential oil from the fruits of Piper tuberculatum Jacq, against lines of Leishmaniabraziliensis (MHOM/CO/8...
