EnglishWith the aim to confirm important nutritional properties, we here report the results obtained from baobab plant tissues analysis (ORAC, DPPH, FRAP). The micronized red fiber display the highest antioxidant activity, among the tested samples in all performed assays; methanolic extracts of this fiber (ME and HME) were prepared and tested in comparison to selected plant extracts by ORAC, DPPH, FRAP and PCL assays, furthermore the total phenols content of ME and HME was measured by Folin-Ciocalteu analysis and characterized by RP-HPLC. HME extract revealed higher antioxidant activity than Blueberry extract (1%) in all performed texts and comparable antioxidant activity to that of Pomegranate extract (40%) in ORAC and DPPH assay; these results are probably due to the high total phenols content (708 ± 14.2mgGAE/g) of the extract.
