Baccharis dracunculifolia, the main source of green propolis, exhibits potent antioxidant activity and prevents oxidative mitochondrial damage. PDF | The present study had as its objective to evaluate the antibacterial and antibiotic modulatory activity of the Baccharis dracunculifolia (DC). This study aimed to analyze the insecticidal potential of ethanol extract of Baccharis dracunculifolia DC, on Spodoptera frugiperda Smith, (Noctuidae) and.
Caryophyllene dracucnulifolia could be binding to the ergosterol, but additional assays are necessary to evaluate if caryophyllene oxide is binding ergosterols in the cellular membrane of P. Three of the isolated compounds i. The highest MIC values for trans-nerolidol, methyl linolenate, the hexanic fraction and amphotericin B were different.
This formula allows the quantification of both growth inhibition values between zero and and cell death values smaller than zero.
The experiments were performed in duplicate and repeated at least once. Email alerts Bacccharis issue alert. Cryptic speciation and recombination in the fungus Paracoccidioides brasiliensis as revealed by gene genealogies.
The MIC was determined after 10 days of incubation. Compounds 2, 3 and 4 displayed antifungal activity against four isolates of Paracocci dioides with MIC values ranging from 3. Paracoccidioides brasiliensis ; Pb Tamoxifen is effective in the treatment of Leishmania amazonensis infections in mice. Oenothein B inhibits the expression of PbFKS1 dracuunculifolia and induces morphological changes in Paracoccidioides brasiliensis.
Ursolic acid appears to be the main cytotoxic substance from the hexane fraction, which corroborated the results of previous studies drwcunculifolia have described the apoptotic effects of ursolic acid on human non-small cell lung cancer A cells [ 2223 ].
In addition, previous studies have shown that Z -nerolidol has leishmanicidal activity against the promastigote forms of L.

The authors alone are responsible for the content and the writing of the paper.
The Paracoccidioides isolates were used after 7 days of growth. The present results showed the biological activities of the isolated compounds and revealed that these compounds may affect the cell surface and growth of P. A simple dracuncukifolia reproducible method to obtain large numbers of axenic amastigotes of different Leishmania species.
Ursolic acid exhibited cytotoxic IC 50 of 8. In addition, a study by Johann et al.
SEINet Portal Network – Baccharis dracunculifolia
Interestingly, only ursolic acid was active against these targets. Antifungal activity of the extracts of some plants used in Brazilian traditional medicine against the pathogenic fungus Paracoccidioides brasiliensis. Taken together, these two studies showed that there were no differences in the activities of the B. The liquid-liquid extraction with solvents of increasing polarity suggested that nonpolar metabolites of B.
In general, the PbB strain was the most susceptible bacchqris all of the compounds. In the present study, we observed that all of the compounds that were isolated from the crude hexanic fraction of B. The parasite dracunculifooia was adjusted to 1. Abstract Paracoccidioidomycosis is a prevalent systemic mycosis in Latin America which requires prolonged treatment with highly toxic antifungals.

The cell morphology of Paracoccidioides brasiliensis Pb18 treated with methyl linolenate, caryophyllene oxide trans-nerolidol or the hexanic fraction of Baccharis dracunculifolia by scanning electron microscopy. Inhibitory effect of terpene nerolidol on the growth of Babesia parasites. Amphotericin B is also used to treat leishmaniasis, but it has several side effects, such as arrhythmia, nephrotoxi city and hepatotoxicity [ 9 ].
When analyzed as the underlying cause of death, PCM is the most important of all systemic mycoses [ 1 ]. We used mixtures of MeOH: Gut microbiome approaches to treat obesity in humans. Thus, the MIC bacfharis are enhanced for caryophyllene oxide in the presence of exogenous ergosterol. Proliferative inhibition, cell-cycle dysregulation, and induction of apoptosis by ursolic acid in bacchairs non-small cell lung cancer A cells. There are only a few studies on the antifungal activity of extracts and compounds from B.
The hexane fraction and the isolated compounds were tested at concentrations ranging from 1.
Phylogenetic analysis reveals a high level of speciation in the Paracoccidioides genus. Paracoccidioidomycosis bqccharis a prevalent systemic mycosis in Latin America which requires prolonged treatment with highly toxic antifungals.
Trypanocidal and antileukaemic effects of the essential oils of Hagenia abyssinica, Leonotis ocymifolia, Moringa stenopetalaand their main individual constituents. Methyl linolenate exhibited the best antifungal activity and resulted in significant changes in the cell morphology of P. The endpoints were determined visually by comparison with the drug-free growth control.
Four compounds were isolated, i. The lowest drug concentration at which no colonies were observed was taken as the MFC value [ 11 ].
