This paper provides a comparative account of the essential oil chemical composition and biological activities five Brazilian species Baccharis (Asteraceae), namely B. microdonta, pauciflosculosa, punctulata, reticularioides, sphenophylla. The compositions three (B. sphenophylla) are reported for first time. Analyses by GC/MS showed notable differences in species. α-Pinene was observed highest concentration (24.50%) reticularioides. Other major compounds included α-bisabolol (23.63%)...
Abstract Viscum album L. (Santalaceae) is an important medicinal plant traditionally used to treat several diseases, including cancer therapy. This paper provides detailed morpho-anatomical characteristics of the leaves, stems and berries subsp. growing as hemi-parasite on branches Malus domestica (Suckow) Borkh. (Rosaceae) aid species identification botanical characterization. Additionally, for first time, microchemical analyses all tissues Energy Dispersive X-Ray Spectroscopy calcium...

In our natural products screening program for mosquitoes, we tested essential oils extracted from different plant parts of Magnolia grandiflora L. their insecticidal and biting deterrent activities against Aedes aegypti. Biting deterrence seeds oil with index value 0.89 was similar to N,N-diethyl-3-methylbenzamide (DEET). All the other were active above solvent control but activity significantly lower than DEET. Based on GC-MS analysis, three pure compounds that only present in seed further...
This study provides a comprehensive account of the various types calcium oxalate crystals found in genus Baccharis and assesses exceptional value crystal macropatterns for taxonomy genus. The morphotype, occurrence, chemical composition stems leaves are studied. 44 species included this were selected based on broad phylogeny-based sampling covering seven subgenera 31 sections. These chosen to represent all main phylogenetic lineages Baccharis; thus, also represents coverage concerning...
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers may exhibit quality issues because of misidentification from similar common names anatomical similarities among related used as feedstock. This study proposes an approach using UPLC‐MS/MS E HPTLC, coupled with morphoanatomical analysis to establish chemical composition pattern data for five species. Subsequently, the methods were validated analyzing commercial...
Abstract We report for the first time presence of cluster crystals calcium oxalate within glandular trichomes and oil bodies in mesophyll Baccharis species. Moreover, comparative leaf anatomy micro‐morphology six species , namely B. illinita microdonta pauciflosculosa punctulata reticularioides sphenophylla is investigated by light scanning electron microscopy. The studied exhibited differences their anatomical features such as morphology cuticle, type occurrence stomata, or absence...
Lavandula dentata, popularly known as lavender, is commonly used in traditional medicine for the treatment of digestive and inflammatory disorders. The objective this study was to analyzed chemical oil composition, antioxidant antimicrobial activities essential anatomical markers leaf stem L. dentata cultivated South Brazil. Essential showed an activity similar rutin gallic acid when by phosphomolybdenum method. However, free radical DPPH ABTS methods, it a slight potential antioxidant....
The present work provides a comparative account of the morpho-anatomy six species Eucalyptus, namely E. badjensis Beuzev. & Welch, benthamii Maiden Cambage, dunnii Maiden, grandis W.Hill, globulus Labill. and saligna Sm., Myrtaceae. Leaf samples these were investigated by light scanning electron microscopy. observed microscopic features that can be useful in identification quality control studied include morphology epicuticular waxes, presence prismatic crystals on leaf surface, midrib shape...
The chemical composition of the essential oils and anatomical structures aerial parts from Baccharis anomala, B. megapotamica ochracea growing in Brazil were studied. volatile constituents isolated by hydrodistillation analyzed gas chromatograph coupled to a mass spectrometer detector (GC-MSD) flame ionization (GC-FID). botanical material was fixed, sectioned prepared according light scanning microtechniques. oil anomala yielded 0.18% showed α-acorenol (16.0%), spathulenol (13.3%)...
Determining the authenticity and quality of plant raw materials used in formulation herbal medicines, teas cosmetics is essential to ensure their safety efficacy for clinical use. Some Passiflora species are officially recognized pharmaceutical compendia various countries have therapeutic uses, particularly as sedatives anxiolytics. However, large number species, coupled with fact that most popularly known passion fruit, increases misidentification problem. The purpose this study make a...
Piper amalago L., Piperaceae, popularly known as jaborandi-manso, is a shrub that spans height of 2–7 m. It can be found in the regions Southern America downward up to south Brazil. Traditionally it used treat digestive problems, heart and burns. This study aims conduct an anatomical investigation analysis leaves stems P. through electron scanning optical micro techniques. The showed has hypostomatic leaf, with subepidermal layer on its surface. There are grandular trichomes resemble sacs,...
Baccharis belongs to the Asteraceae family and comprises a number of medicinal species. brevifolia DC., B. microdonta pauciflosculosa trilobata A.S. Oliveira & Marchiori, which are popularly known in Brazil as "vassouras" ("broom"), all found Southern Brazil. The anatomical features leaf stem were investigated by employing usual light scanning electron microtechniques, means differentiating taxa. following characteristics can be considered diagnostic: occurrence type stomata, midrib, crystal...
Background: As part of the efforts to find natural alternatives for cancer treatment and overcome barriers cellular resistance chemotherapeutic agents, polymeric nanocapsules containing curcumin and/or methotrexate were prepared by an interfacial deposition preformed polymer method. Methods: Physicochemical properties, drug release experiments in vitro cytotoxicity these performed against Calu-3 lung cell line. Results: The colloidal suspensions showed suitable size (287 325 nm), negative...
Antibacterial activity and good mechanical properties are some of the characteristics required for an appropriate film dressing. A novel polymer blend was developed wound healing application. Twenty-four formulations using polymers chitosan, poly(vinyl alcohol) and/or ɛ-Polylysine plasticizer glycerol were designed factorial design then films prepared by casting/solvent evaporation method. Seventeen obtained among twenty-four proposed that characterized Field Emission Scanning Electron...
In southern Brazil, the bottled latex of Synadenium grantii Hook f., Euphorbiaceae, is popularly used as a treatment all types cancer. Similarly, umbellatum Pax. in central western region Brazil for same purpose and manner use. Both plants are known janaúba or leitosinha. The objectives this study were to use pharmacobotanical analysis verify whether these two species, which considered be distinct, actually determine anatomical markers; assist identification differentiation other Euphorbia;...
HIGHLIGHTS Eucalyptus cinerea essential oil (EO) contains 1,8-cineole as the main component. This EO demonstrated antioxidant and antimicrobial properties. reduced viability of Jurkat Calu-3 cells decreased DNA content. had cell death mechanism related to apoptosis.
