Larvicidal potential of piperovatine in the control of cattle tick.

Rhipicephalus (Boophilus) microplus is one of the most important ectoparasites in cattle breeding worldwide, causing direct and indirect losses to animals and producers. Chemical acaricides are utilized in the control of cattle tick and the increase in the development of resistance by ectoparasites makes new alternative necessary. Therefore, research studies have been carried out using bioactive molecules that are quickly degraded and that reduce poisoning to appliers and non-target organisms, environmental contamination and development of resistance.

antioxidant potential and effects of Raddi leaf extract in diabetic rats and determination of chemical composition by HPLC-ESI-MS/MS.

The present study investigated the and antioxidant potential and phytochemical composition of , which is widely used in folk medicine for various therapeutic purposes. The analyses indicated that the hydroethanolic extract (HE) had 312.50 ± 0.

Evaluation of Chemical Composition and Antileishmanial and Antituberculosis Activities of Essential Oils of Piper Species.

Essential oils from fresh Piperaceae leaves were obtained by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC-MS), and a total of 68 components were identified. Principal components analysis results showed a chemical variability between species, with sesquiterpene compounds predominating in the majority of species analyzed. The composition of the essential oil of was described for the first time.
