“…Phytochemical prospection of secondary metabolites has described positive reactions for flavonoids, condensed tannins (proanthocyanidins), and saponins from the fresh leaves of S. vulgaris (Vieira et al, 2005). The same author also demonstrated the antimicrobial activity of the hydroalcoholic extract of fresh leaves and fractions against Bacillus cereus (Gram-positive bacteria) and Pseudomonas aeruginosa (Gram-negative bacteria) (Vieira et al, 2005). The chemical and biological activities of other species of Struthanthus genus are reported in the literature.…”

“…(Loranthaceae), popularly known as erva-de-passarinho, is widely used in the folk medicine of Brazil. The infusion prepared from the aerial parts of the plant is frequently used for stomach ailments, disorders of the respiratory system and in particular, to bathe cutaneous ulcers (Salatino et al, 1993;Vieira et al, 2005). The chemistry and biological activities of S. vulgaris are practically unknown.…”

Context: Struthanthus vulgaris (Vell.) Mart. (Loranthaceae) has been widely used in traditional medicine in Brazil to bathe wounds. Objective: The objective of this study is to investigate the in vitro wound healing effects, together with the antioxidant and antimicrobial activities of S. vulgaris leaf and branch extracts. Material and methods: Ethanol leaf and branch extracts of S. vulgaris were investigated at 1-100 mg/ml concentrations in the scratch assay after 14 h. Antioxidant activity was investigated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay, and the antibacterial activity was tested at concentrations up to 1000 mg/ml against Gram-positive and Gramnegative bacteria by the microdilution test after 24 h. The total phenolic and flavonoid contents were determined by colorimetric methods. Results: Struthanthus vulgaris leaf and branch extracts at 100 mg/ml concentration stimulated migration and proliferation of fibroblasts and enhanced cell numbers by 56.2% and 18.6%, respectively. Antioxidant activity exhibited IC 50 values of 24.3 and 18.9 mg/ml for the leaf and branch extracts, respectively. The ethanol leaf extract showed antimicrobial activity against the Gram-positive Staphylococcus mutans and Staphylococcus aureus bacteria, exhibiting minimum inhibitory concentration values of 125 and 500 mg/ml, respectively. An appreciable total phenolic content in the leaves (813.6 ± 2.7 mg/g) and branches (462.8 ± 9.6 mg/g), and relatively low concentration of flavonoids in the leaves (13.3 ± 4.3 mg/g) and branches (1.9 ± 0.2 mg/g), was detected. Discussion and conclusion: The antioxidant and antibacterial activities, together with the strong ability to stimulate proliferation and migration of fibroblasts, provide some support for the traditional use of S. vulgaris.

“…A ausência de poder antibacteriano do polissorbato já era aguardada uma vez que estudos descritos na literatura comprovam que o mesmo não produz efeitos contra as espécies de cepas testadas (VIEIRA et al, 2005;COSTA et al, 2008 Segundo Brandão et al (2002), seus frutos são utilizados na forma de decocção em gargarejos no tratamento das dores de garganta. O uso do decocto das sementes da sucupira foi constatado na cidade de Itaueira -PI, onde se fez a coleta das informações etnofarmacológicas da sucupira.…”

Palavras-chave: Pterodon emarginatus, Plantas medicinais, Óleos essenciais.ABSTRACT: Evaluation of the antimicrobial activity of the essential oil of sucupira (Pterodon emarginatus). The use of plants for therapeutic purposes is one of the oldest forms of medical practice. This has aroused scientific interest through studies on the antimicrobial activity of extracts and essential oils from plants for the purpose of creating alternatives to combat microorganisms resistant to antibiotics. The objective of this study was to evaluate the potential antimicrobial activity of the essential oil of Pterodon emarginatus against Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853 and Escherichia coli ATCC 25922. The essential oil of P. emarginatus was extracted by the method of hydrodistillation by steam distillation using a modified Clevenger apparatus. Antimicrobial activity was determined using the method of diffusion in solid medium by the pour plate technique using pure essential oil (100%) at the following concentrations: 32%, 16%, 8%, 4%, 2%, 1% and 0.5%. None of the concentrations formed zones of inhibition for Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853 and Escherichia coli ATCC 25922. The present findings suggest that the essential oil of P. emarginatus has no antimicrobial activity against S. aureus. P. aeruginosa and E. coli.
