ABSTRACT

Traditional knowledge is an important source of obtaining new phytotherapeutic agents. Ethnobotanical survey of medicinal plants was conducted in Nossa Senhora Aparecida do Chumbo District (NSACD), located in Poconé, Mato Grosso, Brazil using semi-structured questionnaires and interviews. 376 species of medicinal plants belonging to 285 genera and 102 families were cited. Fabaceae (10.2%), Asteraceae (7.82%) and Lamaceae (4.89%) families are of greater importance. Species with the greater relative importance were Himatanthus obovatus (1.87), Hibiscus sabdariffa (1.87), Solidago microglossa (1.80), Strychnos pseudoquina (1.73) and Dorstenia brasiliensis, Scoparia dulcis L., and Luehea divaricata (1.50). The informant consensus factor (ICF) ranged from 0.13 to 0.78 encompassing 18 disease categories,of which 15 had ICF greater than 0.50, with a predominance of disease categories related to injuries, poisoning and certain other consequences of external causes (ICF  =  0.78) having 65 species cited while 20 species were cited for mental and behavioral disorders (ICF  =  0.77). The results show that knowledge about medicinal plants is evenly distributed among the population of NSACD. This population possesses medicinal plants for most disease categories, with the highest concordance for prenatal, mental/behavioral and respiratory problems.

    ABSTRACT: Ethnopharmacological relevance Obesity is a pandemic disease and its prevalence is still increasing. Moreover, it has important costs to public health. In Brazil, many plants are used for weight loss by overweight or obese people, but there is a lack of scientific basis for this practice. Many ethnobotanical studies aiming to characterize this usage have been published, but they are still limited by the region considered and the diversity of the popular knowledge. Aim of the study The present study was undertaken to systematically review the ethnobotanical surveys regarding the species utilized to reduce body weight in overweight or obese people in Brazil. Methods Ethnobotanical surveys related to this usage and performed in Brazilian regions were systematically found in MEDLINE, LILACS and Scopus. Results Thirty-three studies were included in this review. Fifty species were popularly utilized to lose weight. The most cited species were Baccharis trimera (Less.) DC, Annona muricata L. and Hancornia speciosa Gomes. Camellia sinensis (L.) Kuntze and Hibiscus sabdariffa L. were also cited and are supported by either animal or human investigations that indicate some beneficial activity against obesity. However, for the majority of species cited in the included studies, there is no scientific basis that assures the biological effects of this usage. Many studies have demonstrated important effects of these plants on glycemia, serum lipid levels or body weight control in non-obese conditions, which is not sufficient to recommend the use of these plants to reduce body weight in overweight or obese people. Conclusions Although many plants are popularly used to reduce weight in overweight or obese people in Brazil, there is little scientific evidence corroborating its usage. Based on the ethnobotanical data presented, this review indicates the plants that should be considered for scientifically controlled studies devoted to investigating their effects on obesity.

    ABSTRACT: Ethnopharmacological relevance: Helicteres sacarolha, popularly known in Brazil as 'rosquinha', 'sacarolhas', 'semente-de-macaco', is widely distributed in different phytogeographic zones in Brazil. Preparations from its roots and leaves are employed in popular Brazilian medicine in the treatments of ailments such as peptic ulcer, hypertension among others. Cytotoxicity, acute oral and subchronic toxicity of the hydroethanolic extract of Helicteres sacrolha was investigated as well as the classes of phytochemical present in the extract. Materials and methods: Hydroethanolic (70%) extract of Helicteres sacarolha (HEHs) was prepared by maceration. Potential cytotoxicity was evaluated in CHO-k1 cells. Acute administration of HEHs was done in mice as a single dose up to 5000mg/kg and subchronic oral toxicity study for 30 days in Wistar rats at daily oral doses of 0, 250 and 750mg/kg b.w. Clinical observations and toxicological related parameters were determined every 6 days. Blood was collected for biochemical and hematological analyses, while histological examinations were performed on selected organs. Selected secondary metabolites detected were quantified by UV-spectrophotometry and high performance liquid chromatography (HPLC). Results: The extract was non-cytotoxic to CHO-k1 cells. In acute oral toxicity, there was no mortality or clinical alterations in the female mice, at all doses, except for the transient diarrhea observed at 5000mg/kg acute. Doses up to 2000mg/kg caused no mortality or treatment-related clinical manifestations in the male mice, but treatment-related alterations were however observed at 4000mg/kg, with mortalities recorded at 5000mg/kg. During the subchronic oral toxicity study, no mortality or treatment-related clinical signs were observed. Differences in relative organ weight, hematological parameters and histopathology observations between the treated and the control groups were considered not to be treatment-related. Spectrophotometric analysis revealed the presence of relatively high content of phenolics and flavonoids in HEHs. HPLC analysis confirmed the presence of the quantified compounds and demonstrated the presence of ellagic acid, morin and naringin. Conclusion: Our results confirmed that HEHs have a broad safety margin for therapeutic use.

    ABSTRACT: The aim of this study was to investigate the antimicrobial activity of different extracts and fractions obtained from Hymenaea stigonocarpa stem barks. The cyclohexanic, ethyl acetate, ethanol, aqueous, and hydroalcoholic extracts were obtained by maceration. The hydroalcoholic extract was partitioned, which resulted in the ethyl acetate and aqueous fractions. All extracts and fractions were subjected to phytochemical screening and evaluation of total phenol and tannin contents. An HPLC-DAD and ultrastructural alterations analysis were performed. Terpenes and coumarins were detected in the cyclohexanic extract. Flavonoids and condensed tannins were present in the other extracts and fractions. The extracts with the highest contents of tannins, ethanol (EE), hydroalcoholic (HE), and aqueous fraction (AF) showed also the highest antimicrobial activity. The MIC values ranged from 64 to 526 µg/mL. The chromatographic fingerprints suggest the presence of astilbin and other flavonoids in EE and HE. Presence of the thick cell wall, undulating outer layer, abnormal septa, and leakage of the cytoplasmic contents and absence of cell wall and cell lyses were the main alterations observed on Staphylococcus aureus ATCC 33591 after treatment with the Hymenaea stigonocarpa hydroalcoholic extract. The presence of phenolic compounds like flavonoids and tannins is possibly the reason for the antimicrobial activity.
