Abstract

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