Chemical composition and antioxidant potentials of Kigelia pinnata root oil and extracts

In view of this, we have investigated the in vitro antioxidant effect of these extracts by DPPH assay and examined the phytochemicals in each extract.

Identification of the volatile component was carried out using the peak enrichment technique of reference compounds and as final confirmation of the peak identification by GC-MS, their spectral data were compared afrocana those of NIST library mass spectra. Total phenolic content and reducing power potentials of the extract The total phenolic content was also found chemiccals be higher in KPRE at 0. The Bignoniaceae family is noted for the occurrence of iridoids, naphthoquinones, flavonoids, terpenes, tannins, steroids, coumarins, saponins and caffeic acid in the fruits, stem, cheemicals and roots Akunyili and Kige,ia, [ 2 ]; Houghton et al.
