Abstract The in vitro inhibitory activity of crude EtOH/H 2 O extracts from the leaves and stems Rosmarinus officinalis L. was evaluated against following microorganisms responsible for initiating dental caries: Streptococcus mutans, S. salivarius, sobrinus, mitis, sanguinis , Enterococcus faecalis. Minimum concentrations ( MIC ) were determined with broth microdilution method. bioassay‐guided fractionation leaf extract, which displayed higher antibacterial than stem led to identification...
Primarily known only by the edible fruits of Citrus, Rutaceae comprise a large (c. 160 genera and 1900 species), morphologically diverse, cosmopolitan family. Of its extraordinary array secondary chemical compounds, many have medicinal, antimicrobial, insecticidal, or herbicidal properties. To assist with much-needed suprageneric reclassification studies evolution compounds biogeographic history family, here we included sequence data (from two noncoding regions chloroplast genome-rps16...
Sapindales is an angiosperm order of high economic and ecological value comprising nine families, c. 479 genera, 6570 species. However, family subfamily relationships in remain unclear, making reconstruction the order's spatio-temporal morphological evolution difficult. In this study, we used Angiosperms353 target capture data to generate most densely sampled phylogenetic trees date, with 448 samples 85% genera represented. The percentage paralogous loci allele divergence was characterized...
The in vitro schistosomicidal effects of the essential oil Ageratum conyzoides L. (Ac-EO) against adult worms Schistosoma mansoni is reported this paper. Concerning activity, Ac-EO was considered to be active, but less effective than positive control (praziquantel, PZQ) terms separation coupled pairs, mortality, decrease motor and tegumental alterations. However, caused an interesting dose-dependent reduction number eggs S. mansoni. Precocene I (74.30%) (E)-caryophyllene (14.23%) were...
The Brazilian red propolis (BRP) constitutes an important commercial asset for northeast beekeepers. role of Dalbergia ecastaphyllum (L.) Taub. (Fabaceae) as the main botanical source this has been previously confirmed. However, in addition to isoflavonoids and other phenolics, which are present resin D. ecastaphyllum, samples BRP reported contain substantial amounts polyprenylated benzophenones, whose was unknown. Therefore, field surveys, phytochemical chromatographic analyses were...
Changes in leaf anatomy and ultrastructure are associated with physiological performance the context of plant adaptations to climate change. In this study, we investigated isolated combined effects elevated atmospheric CO2 concentration ([CO2]) up 600 μmol mol-1 (eC) temperature (eT) 2°C more than ambient canopy on ultrastructure, anatomy, physiology Panicum maximum Jacq. grown under field conditions using free-air carbon dioxide enrichment (FACE) controlled enhancement (T-FACE) systems....
Abstract Rutaceae is a family of angiosperms well known for the economically important genus Citrus . The division into subfamilies still inadequate and provisional. Previous phylogenetic studies at level are characterized by limited sampling genera lack several crucial taxa. Here, we present study based on six nuclear plastid markers including 87.7% currently accepted genera, which more than twice as many in previous studies. Seven included analysis first time. Most clades resolved with...
The position of the plant genus Pitavia within an infrafamilial phylogeny Rutaceae (rue, or orange family) was investigated with use two non-coding regions from cpDNA, trnL-trnF region and rps16 intron. only species genus, punctata Molina, is restricted to temperate forests Coastal Cordillera Central-Southern Chile threatened by loss habitat. traditionally has been treated as part tribe Zanthoxyleae (subfamily Rutoideae) where it constitutes monogeneric Pitaviinae. This are characterized...
Abstract The chemical composition and the in vitro schistosomicidal effects of essential oil Plectranthus neochilus (PN‐EO) grown Southeast Brazil was studied. β ‐Caryophyllene ( 1 ; 28.23%), α ‐thujene 2 12.22%), ‐pinene 3 12.63%), 4 6.19%), germacrene D 5 5.36%), caryophyllene oxide 6 5.37%) were major constituents. This differed from that previously reported for specimens harvested Africa. Concerning activity against adult Schistosoma mansoni worms, PN‐EO considered to be active, but less...
This work used the broth microdilution method to investigate antimicrobial activity of essential oil obtained from leaves Plectranthus neochilus (PN-EO) against a representative panel oral pathogens. We assessed this in terms minimum inhibitory concentration (MIC). PN-EO displayed moderate Enterococcus faecalis (MIC = 250 μ g/mL) and Streptococcus salivarus g/mL), significant sobrinus 62.5 sanguinis mitis 31.25 Lactobacillus casei interesting mutans 3.9 g/mL). GC-FID GC-MS helped identify...
The in vitro activity of the crude hydroalcoholic extract aerial parts Miconia langsdorffii Cogn. was evaluated against promastigote forms L. amazonensis, causative agent cutaneous leishmaniasis humans. bioassay-guided fractionation this led to identification triterpenes ursolic acid and oleanolic as major compounds fraction that displayed highest activity. Several semi-synthetic derivatives were prepared, find out whether more active could be obtained. Among these acid-derived substances,...
This paper reports on the chemical composition, in vitro antischistosomal effects, and cytotoxicity of essential oil from leaves Lavandula angustifolia Mill., Lamiaceae, grown Southeastern Brazil. Borneol (22.4%), epi-α-muurolol (13.4%), α-bisabolol (13.1%), precocene I (13.0%), eucalyptol (7.9%) were major constituents. Incubation with at 200 μg/ml killed all adult S. mansoni worms after 24 h (LC50 117.7 103.9 120 incubation, respectively). At a concentration 50 μg/ ml, significantly...
The in vitro schistosomicidal effects of the essential oil obtained from Tagetes erecta L. Asteraceae, leaves (TE-EO) collected Brazil against Schistosoma mansoni worms are reported this paper. caused a significant decrease motor activity at 50 µg/mL as minimal concentration after 24 h. This also death all parasites and separation coupled pairs into individual male female 100 viability adult worm groups treated with TE-EO was similar to that praziquantel (positive control). In addition,...
We have investigated the chemical composition and antibacterial activity of essential oil Dysphania ambrosioides (L.) Mosyakin & Clemants (Chenopodiaceae) ( DA ‐ EO ) against a representative panel cariogenic bacteria. also assessed in vitro schistosomicidal effects on Schistosoma mansoni its cytotoxicity to GM 07492‐A cells . Gas chromatography GC gas chromatography‐mass spectrometry / MS revealed that monoterpenes cis ‐piperitone oxide (35.2%), p ‐cymene (14.5%), isoascaridole (14.1%),...
