EXTRACTION AND ISOLATION OF INDOLE ALKALOIDS FROM Tabernaemontana catharinensis: TECHNICAL AND ECONOMICAL ANALYSIS
Leishmaniasis is a parasitic infection that is considered worldwide one of the most important public health problem, affecting more than 12 million people with an estimated number of 2 million new cases occurring annually. Among the compounds isolated from Tabernaemontana catharinensis, coronaridine and voacangine are the indole alkaloids which have antileishmanial activity. In this work, the t...
متن کاملSUPERCRITICAL EXTRACTION OF INDOLE ALKALOIDS FROM Tabernaemontana catharinensis: AN EVALUATION OF THE COSOLVENT ON THE EXTRACT COMPOSITIONS
Tabernaemontana catharinensis is a tree rich in indole alkaloids, such as coronaridine and voacangine that have antileishmanial activity. SFE from T.catharinensis using CO2 + 5.1% (m/m) of cosolvent (ethanol, isopropyl alcohol, methanol, water and their mixtures) was studied. The global yields and the compositions of extracts were determined. The data were taken at 250 bar, 45oC, and total solv...
متن کاملChemical derivatization and mass spectral libraries in metabolic profiling by GC/MS and LC/MS/MS.
An overview is presented of gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS), the two major hyphenated techniques employed in metabolic profiling that complement direct 'fingerprinting' methods such as atmospheric pressure ionization (API) quadrupole time-of-flight MS, API Fourier transform MS, and NMR. In GC/MS, the analytes are normally derivati...
متن کاملPhytochemical Analysis by HPLC–HRESI-MS and Anti-Inflammatory Activity of Tabernaemontana catharinensis
Tabernaemontana catharinensis (Apocynaceae) has been popularly used by folk medicine because of its anti-inflammatory, analgesic, and antiophidic properties. This study aims to analyze the flavonoids composition of the hydroethanolic extract and of the ethyl acetate (EtOAc) and butanol (BuOH) fractions of T. catharinensis leaves, as well as to evaluate their anti-inflammatory activity using in ...
متن کاملPhytochemical 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...
