In the presente study was evaluated in vitro antimicrobial activity of the extract of the stem bark and fruit juca against microorganisms of the oral cavity. This was an experimental laboratory study in which was evaluated the antimicrobial activity of aqueous extracts 7.5% in dilutions ranging from 1:1 to 1:512, using the technique of agar diffusion. Standard strains used were: Streptococcus mutans (ATCC 25175), Streptococcus oralis (ATCC 10557, Lactobacillus casei (ATCC 7469), Candida albicans (INCQS 40040) and Streptococcus salivarius (ATCC 7073). Chlorhexidine 0.12 % was used as a positive control. The results of the agar diffusion showed that when assessed against L. casei, extract of the fruit was more effective, with MICs 9.3 mg/mL compared to stem bark was 37.5 mg/mL. When the fruit extract were tested against S. oralis and S. mutans MIC values were the same and twice, respectively , when compared with values obtained with the extract of the stem bark . With respect to C. albicans, the MIC value for the extract of the fruit and stem bark was 18.7 mg/mL. While against S. salivarius extract of the stem bark had MIC value of 37.5 mg/mL and the extract of the fruit was inactive. It can be concluded that the extract of the stem bark of juca showed satisfactory antimicrobial activity against pathogens of the oral cavity and superior to the extract of the fruit.In the present study was evaluated in vitro antimicrobial activity of the extract of the stem bark and fruit jucá against microorganisms of the oral cavity.

This paper reports the bioguided fractionation of an ethanol extract of X. myrianthum (Cham.) Sprague stems (EEXMS) for antiviral effects against human herpes virus type 1 (HSV-1), dengue virus 2 (DENV-2), murine encephalomyocarditis virus (EMCV) and vaccinia virus (VACV) that afforded XM-1 as an active compound. Spectroscopic analyses allowed the identification of XM-1 as arjunic acid whose occurrence in the Bignoniaceae and anti-DENV-2 activities are reported for the first time. X. myrianthum is revealed herein as a source of an antiviral compound and fractions.Herbal constitute a form of complementary therapy on health needs. Their use has grown in population in several countries, including Brazil, where the federal government encourages the use of herbal treatments in the public health system. Given the current scenario of the search for natural treatments, this study aimed to characterize the use of herbal medicines in the districts of Barra Mansa and Volta Redonda/RJ. The expectation is that the information gathered will assist municipal actions for the implementation of herbal medicine in public health. It was observed that most herbal medicines marketed is sold by prescription. The acquisition focuses on monodrogas anxiolytic action, with the Passiflora incarnata L. present in 14,29 % of the marketed formulations. The inserts of the highest-selling herbal medicines contain legal wording regulated by ANVISA. Among the users interviewed, 70% reported using herbal medicines, mostly female (68%), without having a specific economic pattern, aged 19 and 30 years, with a degree of complete or incomplete higher education. Of these, 31% use herbal or prescription for self medication and believe that herbal medicines are not toxic, can make good health.Several studies have discussed bromeliads as breeding grounds for Aedes aegypti L., a dengue vector. The toxicity of crude extracts of Aechmea fasciata (Lindley) Baker (Bromeliaceae) and Neoregelia compacta (Mez) LB Smith (Bromeliaceae) on A. aegypti larvae was evaluated in this study. Leaves of N. compacta were ground up with ethanol and distilled water, hexane and ethyl acetate to produce hydro alcoholic, hexane and ethyl acetate extracts. Flowers and leaves of A. fasciata were macerated in ethyl acetate to obtain an ethyl acetate extract. The bioassays were performed with application of these extracts to the breeding medium of L3 larvae of A. aegypti. In this study, larval and pupal viability, emergence and mortality were evaluated. The results from the bioassays indicated that these extracts were highly toxic: LD50=39.4µg/mL for A. fasciata and LD50= 23 µg/ mL for N. compacta. The data suggest that, within the search for larvicidal phytoproducts, these bromeliads are sources of active bioproducts for dengue vector mosquito control.
