Phytochemical profile and determination of cytotoxicity, acute oral toxicity, genotoxicity, and mutagenicity of aqueous and ethanolic extracts of (A. St.-Hil.) A. Robyns.

, popularly known as "embiratanha," is widely used by traditional communities as anti-inflammatory and analgesic agent. This study aimed to determine the phytochemical profile as well as cytotoxicity, acute oral toxicity, genotoxicity, and mutagenicity attributed to exposure to aqueous (AqEx) and ethanolic (EtEx) extracts of embiratanha bark. Phytochemical screening was conducted using thin-layer chromatography (TLC).

Evaluation of the Antioxidant and Antifungal Actions of the Optimized Crude Extract and Fractions from the Aerial Parts of Acanthospermum hispidum.

This study investigated the phytochemical characteristics of the aerial parts of Acanthospermum hispidum, by chromatographic and spectrophotometric methods, and evaluated the antioxidant and antifungal activities of the crude extract and polyphenol-enriched fractions of the species. The phytochemical prospection showed the presence of polyphenols from the groups of hydroxycinnamic derivatives and flavonoids in the crude extract (CE) and fractions of the aerial parts of A. hispidum.

Chemical and antibacterial analysis of leaves extract and fractions against multidrug resistant bacteria.

The chemical composition, the antioxidant and antimicrobial potential of crude extract from leaves and their enriched fractions was studied. Phytochemical analyses were performed by TLC and HPLC, and the antioxidant capacity was verified by DPPH and ABTS. The Minimal Inhibitory/Bactericidal Concentration was conducted against twenty-two bacteria to select five strains susceptible to extracts/fractions and resistant to the antibiotics tested.

Use of mycorrhizal fungi releases the application of organic fertilizers to increase the production of leaf vitexin in yellow passion fruit.

Background: Low-cost organic fertilizers, such as coconut powder and vermicompost, and arbuscular mycorrhizal fungi (AMF) may benefit the Passiflora edulis f. flavicarpa plant. However, it has not been established whether the joint application of these inputs may increase the production of vitexin and other molecules associated with the phytotherapeutic properties of this plant.

Fruit Crude Extract and Fractions Show Anti-Inflammatory, Antioxidant, and Antinociceptive Effect and Increase Cell Viability .

Background: ( is found throughout the northeastern region of Brazil, where it has been used in folk medicine with beneficial effects on many inflammatory disorders.

Purpose: This study investigated the phytochemical composition of the crude extract and fractions of fruit and evaluated its anti-inflammatory and antinociceptive activities and effect on cell viability .

Methods: Characterization of polyphenols present in crude extract (CE), hydroalcoholic fractions of 20-80% ethanol (CE20, CE40, CE60, and CE80), aqueous fraction (AqF), and ethyl acetate (EAF) fractions of fruit was performed by chromatographic analysis.

Assessment of 28-day oral toxicity and antipyretic activity of the saline extract from Pilosocereus gounellei (Cactaceae) stem in mice.

Ethnopharmacological Relevance: Pilosocereus gounellei is a plant found in the Brazilian Caatinga and is popular due to its traditional uses in the treatment of inflammation. The present study was conducted to investigate the sub-acute toxicity of the saline extract from the stem of P. gounellei.

Production of biomolecules of interest to the anxiolytic herbal medicine industry in yellow passionfruit leaves (Passiflora edulis f. flavicarpa) promoted by mycorrhizal inoculation.

Background: Our contemporary way of life has led us to consume high amounts of chemically-synthesized allopathic medicinal products and anxiolytics to which a viable alternative is the use of Passiflora-based herbal medicines with composition containing vitexin, a flavonoid with anxiolytic and antidepressant properties. Arbuscular mycorrhizal fungi (AMF) are known for enhancing the production of biomolecules, however, increase production of phytochemistry in Passiflora edulis f. flavicarpa has not been reported in the literature.

Organic Extract of Jacq. Leaf Inhibits Interferon-γ Secretion and Has Bacteriostatic Activity against and .

Jacq. (Acanthaceae) leaves currently found in the Brazilian north-east are widely used to treat diabetes, menstrual pains, asthma, and other disorders. This work aimed to identify the phytochemical characterization and biological activities of leaf extracts.

Saline extract of Pilosocereus gounellei stem has antinociceptive effect in mice without showing acute toxicity and altering motor coordination.

People broadly use medicinal plants although their safety and efficacy are often neglected. Several Cactaceae plants are used for medicinal purposes, but Pilosocereus gounellei (xique-xique) has been little studied for their pharmacological properties. In this study, a saline extract from Pilosocereus gounellei stem was evaluated for acute toxicity, effects on motor function, and antinociceptive activity in mice.
