Abstract
Spectrophotometric assays (Folin–Ciocalteu, ferric-reducing=antioxidant power, cupric-reducing antioxidant capacity, and b-carotene linoleate model system) have been used to evaluate the total phenolics and flavonoids in kiwi fruit cultivars in ethanol and water extracts. Fluorescent and infrared measurements were correlated with the obtained spectroscopic data. It was found that the contents of the bioactive compounds and the level of antioxidant activity in different extracts differ significantly (p<0.05). Bioactive compounds and antioxidant activities were significantly higher in two kiwi fruit cultivars (‘‘Bidan’’ and ‘‘SKK12’’) than inotherstudiedsamples.Toourknowledgethisisthefirstreportshowingthedifferencesandsimilaritiesinnewkiwifruitcultivars, using thesespectroscopic data.Theethanolextractsofthese cultivars exhibitedhighbinding propertieswithhuman serumalbumin compared with rutin. In conclusion, the applied analytical methods showed the main compounds in the kiwi fruit cultivars and can be used for determination of these compounds in any plants. The relative knowledge would contribute to the pharmaceutical development and clinical application of extracts of kiwi fruit extracts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
