Casearia decandra leaves present anti-inflammatory efficacy in a skin inflammation model in mice.

Ethnopharmacological Relevance: Casearia decandra (guaçatonga) is popularly used as an anti-inflammatory. We investigated the antioxidant and anti-inflammatory effect of C.decandra leaves (CdE) ethanolic extract and of the rutin standard (present in the CdE).

Phytochemical analysis and evaluation of antioxidant and antimycobacterial activity of from Brazil.

(Spreng.) Esc. (Rhamnaceae, Colletieae) is a medicinal plant, threatened with extinction in Brazil, presenting great morphological variability.

Safety assessment of ethanolic extract of Olea europaea L. leaves after acute and subacute administration to Wistar rats.

Olea europaea L., popularly known as olive, is a plant widely used worldwide. Its leaves, fruit and oil are extensively consumed and present important pharmacological properties.

Antimicrobial, antitrypanosomal and antibiofilm activity of Equisetum hyemale.

This study evaluates, for the first time, the antibiofilm, antimicrobial and antiparasitic potential of crude extract and fractions of stems of Equisetum hyemale against several infectious agents (bacteria, fungi, Mycobacterium and Trypanosomes) by broth microdilution technique and investigates the phenolic composition of the plant by high performance liquid chromatography. The crude extract and fractions showed antimicrobial activity, as they were capable of inhibiting the growth of bacteria in minimal inhibitory concentrations (MICs) ranging from 52.4 mg/mL to 3.

Ethnopharmacological study and topical anti-inflammatory activity of crude extract from Poikilacanthus glandulosus (Nees) Ariza leaves.

Ethnopharmacological Relevance: Ethnopharmacological studies are important tools as records and documentation of the empirical uses of medicinal plants in traditional communities with the purpose of generating useful knowledge to lead to the development of new medicines, biodiversity conservation and enhancement of knowledge and local culture. Poikilacanthus glandulosus is widely used by the population of City of Santiago, in Brazil, nevertheless, it does not have any validation regarding its use and its medicinal effects.

Aim: The objective of this study was to perform one ethnopharmacological survey about P.

Development and Validation of an HPLC-DAD Analysis for Flavonoids in the gel of Scutia buxifolia.

Recent interest in flavonoids has increased greatly due to their biological and pharmacological activities. Flavonoids consist of a large group of low molecular weight polyphenolic substances, naturally occurring in fruits, vegetables and tea, and are an integral part of the human diet. Quercetin and rutin are bioactive markers of Scutia buxifolia and no analytical methods reported so far, associated with quality control of polyherbal formulations containing this species.

Effect of black grape juice against heart damage from acute gamma TBI in rats.

The aim of this study was to evaluate the potential positive effect of black grape juice (BGJ) on lipid peroxidation considering Total Body Irradiation (TBI) in Wistar rats. As a potential feasible means of evaluation in situ, blood serum lactate dehydrogenase (LDH) levels were evaluated as a marker for heart damage from acute radiation syndrome (ARS). Twenty rats were divided into four groups, two of them being irradiated by gamma-rays from a Co-60 source.

Antiinflammatory effects of Viola tricolor gel in a model of sunburn in rats and the gel stability study.

Ethnopharmacological Relevance: Viola tricolor, popularly known as heartsease has been empirically used in several skin disorders, including burns.

Aim Of The Study: The objective of this study was investigate the antinociceptive and antiinflammatory effect of a gel containing extract of Viola tricolor flowers on thermal burn induced by UVB irradiation and to perform gel stability study.

Methods: The antinociceptive and antiinflammatory effect were evaluated by static and dynamic mechanical allodynia model, paw edema, and neutrophilic cell infiltration.

HPLC analysis of phenolics compounds and antioxidant capacity of leaves of Vitex megapotamica (Sprengel) Moldenke.

Vitex megapotamica (Sprengel) Moldenke belongs to the Verbenaceae family and is popularly known as "tarumã". The antioxidant capacity of fractions and crude extract from the leaves of V. megapotamica were determined in this study through the capacity to remove reactive species and phenolic compounds were quantified in the various fractions.

Hepatotoxicity evaluation of aqueous extract from Scutia buxifolia.

Nowadays there is an increase in the number of people taking herbals worldwide. Scutia buxifolia is used for the treatment of hypertension, but little is known about its action on liver. Thirty-two Wistar rats were divided into four groups: control and groups treated during 30 days with 100, 200 and 400 mg of lyophilized aqueous extract of S.
