Chemical Analysis and Evaluation of Antioxidant, Antimicrobial, and Photoprotective Activities of Schinopsis brasiliensis Engl. (Anacardiaceae)

Abstract

Schinopsis brasiliensis Engl. is a native plant of Caatinga which has high concentrations of compounds capable of absorbing ultraviolet light, suggesting its potential application for the development of sunscreen preparations. After its identification and collection, this vegetable drug was submitted to a physicochemical analysis through the preparation of ethanolic extract. The phytochemical screening and analysis of extracts were carried out by high-performance liquid chromatography (HPLC) evaluation. The antioxidant activity of the extract was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and β-carotene bleaching test. Inhibitory hemolytic activity and morphological deformation of erythrocytes induced by H2O2 were also demonstrated and the antimicrobial activity was analyzed by the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) method. For the in vitro determination of the sun protection factor (SPF), the spectrophotometric method was used. From the analyses carried out with this species, this plant showed significant results for the antioxidant and antimicrobial activities, as well as sunscreen action. Important flavonoids were identified. These data are an important step for the development of new photoprotective cosmetic with Caatinga species, revealing importance and representing another incentive for the preservation of the species involved and analyzed in the study.

“…Additionally, the extracts obtained from Schinopsis brasiliensis Engl. exhibited antimicrobial activity against both gram-positive and gram-negative bacteria with the MICs ranging from 390 to 1,250 μg/mL [48].…”

Metabolomic analyses of dry lemon slice during storage by NMR

“…In citrus juices, NEB is due to the reactions of sugars, amino acids, and ascorbic acid. The decomposition of ascorbic acid is the leading browning reaction occurred during the storage of orange juice (Lima‐Saraiva et al., 2017).…”

Antibacterial efficacy of hubballi propolis against aggregatibacter actinomycetemcomitans one of the major causative organisms of perimplantitis: An In vitro study

“…If the MIC ranged from 100 to 500 μg/ml, it is regarded to be moderate while MIC more than 500 μg/ml is considered poor. [ 17 ] Hubballi Propolis (WEP and AEP) were moderately active against the Aggregatibacter actinomycetemcomitans with the MIC range from 0.1 to 0.25 mg/ml (100–250 μg/ml) Tables 1 and 2 . This result is in accordance with the research done by Gebara et al .…”
