We investigated ten honey samples from the Discovery Coast of Bahia, Brazil, to confirm the three predominant flower sources indicated by regional beekeepers: Brazilian peppertree - Schinus terebinthifolia Raddi; eucalyptus - Eucalyptus L'Hér. spp.; and velame - Croton L. spp.. The honeys were collected in five Southern Bahia municipalities - Belmonte, Eunápolis, Guaratinga, Itabela and Porto Seguro. The samples underwent acetolysis and, after slides mounting, the pollen types were identified and counted to determine the frequency classes. The pollen spectra revealed 31 pollen types in 27 genera and 17 families. The palynological analysis confirmed the predominant eucalyptus flower source indicated for four honey samples from Belmonte, Eunápolis, Itabela and Porto Seguro. Three honey samples previously indicated with predominant eucalyptus and velame flower sources had no predominant pollen. Eucalyptus predominated as the main flower source for another three samples previously indicated by beekeepers as Brazilian peppertree and velame. We conclude that regional honeys marketed as having a predominant flower source may have distinct botanical origin. This demands further research aimed at reviewing which bee plants provide resources for monofloral, bifloral and plurifloral honeys in the Bahian Discovery Coast.

Peritoneal histopathological changes and cultures after autogenous fecal peritonitis induced in elderly rat model: response to intravenous use of meropenem and intra-abdominal inoculation of 10% aqueous extract of Schinus Terebinthifolius Raddi (Anacardiaceae).

Purpose: To evaluate the peritoneal histopathological changes and culture after the use of intravenous meropenem and intra-abdominal inoculation of 10% aqueous extract of anacardiaceae, in elderly rat model after autogenous fecal peritonitis induced.
Methods: Thirty 18-month-old Wistar rats received induction of autogenous fecal peritonitis and then were stratified into two groups: study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem (40 mg/kg) and intraperitoneal 10% aqueous extract of anacardiaceae. Animals were monitored for 15 days until euthanasia.

This research aimed to assess the bioaccumulation capacity of the species and L. using organic amendments to the phytoremediation of total chromium in the mid-zone of the Añashuayco Ravine, Uchumayo, Arequipa, impacted by tanneries from the Rio Seco Industrial Park. Additionally, it analyzed total chromium concentrations, soil physicochemical properties, and morphological changes in plants with and without organic matter.

Flavonoids are particularly interesting because they have a broad spectrum of biological effects, including antioxidant and free radical scavenging activities. In this work, solid-liquid microextraction and dispersive liquid-liquid microextraction enhanced by ultrasound were developed and compared with the conventional method (Soxhlet extraction) to optimize the extraction of four flavonoids: rutin, quercitrin, quercetin, and myricetin in samples of Schinus molle (Aguaribay). During the development of the analytical method, different chemometric tools were used to optimize the microextraction procedure.
