Abstract
Albizia zygia is a plant widely
used in West Africa in the traditional treatment of several pathologies,
including diabetes. The objective of this work is to identify the structures of
the molecules, to quantify the phytocompounds, and to evaluate the antioxidant
activity of aqueous and hydroethanolic extracts of Albizia zygia.
Compound identification was performed using FT-IR spectroscopy and HPLC-ESI-QTOF-MS/MS mass spectrometry. Antioxidant
activity was assessed using Abts and DPPH methods. Analysis of the
HPLC-ESI-QTOF-MS/MS and IR spectra revealed the presence of alizarin and 2,6-di-tert-butyl-4-hydroxymethylphenol. Phytocompound
quantification showed that total polyphenol content, expressed as gallic acid
equivalent (GAE), ranged from 9.78 ± 0.001 to 32.83 ± 0.28 mg GAE /g for the
two Albizia zygia extracts. The hydroethanolic extract of Albizia
zygia stem bark has the highest total flavonoid content, with a value of
16.00 ± 0.50 mg QE/g, and total tannin content, with a value of 10.78 ± 0.009
mg QE/g. The hydroethanolic extract of Albizia zygia leaves exhibits
good antiradical activity compared to vitamin C. The results of this study
could confirm its use as a traditional medicine in Korhogo.
