Phytochemical analysis and antioxidant capacity of Tabernaemontana catharinensis A. DC. Fruits and branches.
The antioxidant capacity of the crude extract and fractions of Tabernaemontana catharinensis fruits and branches, was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the content of polyphenols, flavonoids, alkaloids and condensed tannins were determined by the spectrophotometric method. The ethyl acetate fraction of the fruits and the n-butanol fraction of the branches showed I...
متن کاملChemical Constituents Antioxidant and Anticholinesterasic Activity of Tabernaemontana catharinensis
The present work aimed to analyze the alkaloid content of the ethanolic extract of Tabernaemontana catharinensis (Apocynaceae family) and its fractions as well as to evaluate their antioxidant and anticholinesterasic activities. The analyses of the ethanolic extract of T. catharinensis by mass spectrometry allowed identifying the presence of the alkaloids 16-epi-affinine, coronaridine-hydroxyin...
متن کاملSFE OF PHARMACOLOGICAL COMPOUNDS FROM Tabernaemontana catharinensis: ANALYSIS OF THE ANTIOXIDANT AND ANTIMYCOBACTERIAL ACTIVITIES
In the present work the pharmacological activities of SFE extracts from T. catharinensis were evaluated. The SFE extracts were obtained using supercritical CO2 plus ethanol as cosolvent (4.6 and 9.2% m/m) at pressures of 250 and 300 bar and temperatures of 35, 45, and 55oC. The crude extracts were solvent-fractionated (hexanic fraction, alkaloid, and aqueous fractions) and analyzed by Thin-laye...
