Antimicrobial activity of propolis from the Brazilian stingless bees Melipona q...

Melipona quadrifasciata anthidioides and Scaptotrigona depilis are species of stingless bees capable of producing propolis, which has considerable bioprospecting potential. In this context, the objective of this study was to determine the chemical compositions and evaluate the antimicrobial activity of propolis produced by M. q. anthidioides and S. depilis. The ethanolic extracts of propolis of M. q. anthidioid...

Diversity, chemical constituents and biological activities of endophytic fungi ...

Schinus terebinthifolius Raddi is a medicinal plant widely used for the treatment of various diseases. The secondary metabolites responsible for the pharmacological properties can be produced directly by the plant or by endophytic fungi. The objective of this study was to evaluate the diversity of endophytic fungi of di erent parts of S. terebinthifolius and to identify chemical compounds produced by endophytes...

Microbiological quality, chemical profile as well as antioxidant and antidiabet...

Schinus terebinthifolius Raddi, commonly known as Brazilian peppertree, is a plant species widely used in Brazilian traditional medicine for various purposes. The objective of this study was to assess the microbiological quality, safety, chemical profile as well as antioxidant and antidiabetic potentials of different parts of S. terebinthifolius. Microbiological analysis of the methanolic extracts of the roots ...

Physicochemical characterization, microbiological quality and safety, and pharm...

Hancornia speciosa Gomes is a fruit tree, commonly known as the mangaba tree, which is widespread throughout Brazil. The leaves of this plant are used in traditional medicine for medicinal purposes. Thus, the objective of this study was to perform a physicochemical characterization, identify the lipophilic antioxidants and fatty acids, and determine the microbiological quality and safety of H. speciosa leaves. ...

Chemical profile and antioxidant, anti-inflammatory, antimutagenic and antimicr...

Licensee MDPI, Basel, Switzerland. Geopropolis is a resin mixed with mud, produced only by stingless bees. Despite being popularly known for its medicinal properties, few scientific studies have proven its biological activities. In this context, the objective of this study was to determine the chemical composition and antioxidant, anti-inflammatory, antimutagenic and antimicrobial activities of the Melipona orb...

Chemical composition and pharmacological effects of geopropolis produced by Mel...

Stingless bees produce geopropolis, which is popularly described for its medicinal properties, but for which few scientific studies have demonstrated pharmacological effects. The objective of this study was to investigate the chemical composition of the geopropolis of Melipona quadrifasciata anthidioides and to evaluate its antioxidant, antimutagenic, anti-inflammatory, and antimicrobial activities. The composi...

The Chemical Profile of Senna velutina Leaves and Their Antioxidant and Cytotox...

Natural products can be a source of biomolecules with antioxidant activity which are able to prevent oxidative stress-induced diseases and show antitumor activity, making them important sources of new anticancer drug prototypes. In this context, this study aimed to analyze the chemical composition of an ethanol extract of Senna velutina leaves and to assess its antioxidant and cytotoxic activities in leukemic c...

Chemical composition, antioxidante and antimicrobial activity of the leaves of ...

Hancomia species Gomes in a Brazilian tree which fruit is popularly know as mangaba. In this study we aimed (I) to characterize the chemical composition and energy content and to evaluate the antioxidant and antimicrobial activities of the ethanol {EEHS) and methanol (EMHS} extracts from H species leaves.
