Phytochemical characterization, toxicity and pharmacological profile of the central effects of the fixed fruit pulp oil of Mauritia flexuosa L.F. (buriti).

Anxiety and depression are mental disorders that have been exponentially increasing over the last decades. Psychopharmacology emerged to try to alleviate the symptoms of these disorders; however, the side effects and the time it takes to achieve the desired effect are factors that decrease the search for and adherence to treatment. To remedy this situation, new compounds capable of improving the performance of these medications and reducing their adverse effects have been sought.

Antimicrobial resistance has become a growing public health concern in recent decades, demanding a search for new effective treatments. Therefore, this study aimed to elucidate the phytochemical composition and evaluate the antibacterial activity of the essential oil obtained from the fruits of Jacq. (EOPT) against strains carrying different mechanisms of antibiotic resistance.

Antibacterial Activity and Anxiolytic Effect in Adult Zebrafish of Genus L. Species.

Species belonging to the genus are used worldwide as foods, beverages, and seasonings. Studies have demonstrated that these species have antioxidant, sedative, analgesic, anti-inflammatory, and antipyretic activities. This work aimed to evaluate the antibacterial activity and anxiolytic effect by different pathways of essential oils and ethanolic extracts of three species of (, , and ).

Chemical composition variation of essential oils of Desf. from different vegetational formations.

This study aims to provide information about the chemical profile of the essential oil from resin in areas of , , and Humid Forest. In order to obtain the essential oils, oil-resin was submitted to hydrodistillation process, and the chemical components were analyzed by gas chromatography coupled to mass spectrometry (GC/MS). Twenty-six constituents were identified in the essential oil of resin, of which 12 were present in , 15 in and 18 in Humid Forest, with β-bisabolene, caryophyllene oxide, γ-muurolene, α-caryophyllene and β-caryophyllene common to the three phytophysiognomies.

Comparative analysis of chemical profiles and antioxidant activities of essential oils obtained from species of Lippia L. by chemometrics.

Due to the importance of diseases associated with oxidative stress, the search for natural antioxidants proves to be essential. This work aimed to compare the chemical composition and antioxidant potential of essential oils from the genus Lippia L. through chemometric analysis.

Chemical Profile and Evaluation of the Antioxidant and Anti-Acetylcholinesterase Activities of L. (Annonaceae) Extracts.

This study presents the chemical profile of extracts from the pulp and seed of L., as well as the evaluation of their antioxidant and acetylcholinesterase inhibition activities. In the chemical prospection, qualitative assays were performed, and the contents of total phenols, flavonoids, vitamin C, and carotenoids were quantified.

Influence of seasonal variation on phenolic content and in vitro antioxidant activity of Secondatia floribunda A. DC. (Apocynaceae).

This study reports the effects of seasonal variation on the total polyphenol and flavonoid content and the in vitro antioxidant activity of Secondatia floribunda A. DC. The extracts were prepared from the inner bark and heartwood of samples harvested in the 2015 to 2016.

Chemical analysis and evaluation of antioxidant and antimicrobial activities of fruit fractions of L. f. (Arecaceae).

Background: Fruit consumption is currently considered beyond the nutritional aspects because of the important roles in disease prevention and benefits to health. The objective of this study was to characterize the chemical profile and evaluate the antioxidant and antimicrobial properties of different fractions obtained from fruit pulps of (MFFs).

Methods: Initially, chloroform, ethyl acetate and ethanol fractions were obtained from the pulps.

In vitro antimicrobial activity of the essential oil from Vanillosmopsis arborea Barker (Asteraceae) and its major constituent, α-bisabolol.

Vanillosmopsis arborea Barker (Asteraceae), commonly known as "candeeiro" is an endemic tree to the Caatinga biome, in northeast Brazil. The major component of its essential oil is α-bisabolol, a monocyclic sesquiterpene alcohol with several biological activities reported. In this study, the antimicrobial activity of the essential oil of V.

Development and validation of a rapid RP-HPLC-DAD analysis method for the quantification of pilocarpine in Pilocarpus microphyllus (Rutaceae).

A method using high performance liquid chromatography with diode array detector (HPLC-DAD) for identification and quantification of pilocarpine in the extract of Pilocarpus microphyllus, popularly known as jaborandi. The analysis was conducted using RP-18 column (250 mm × 4.6 mm x 5 μm id) and a buffer solution composed of acidified water, phosphoric acid and triethylamine and methanol as a mobile phase in a flow rate of 1.
