Özet

Bioactive compounds such as phenolics, anthocyanins and carotenoids were investigated in Berberis plant with purple (PB), red (RB) and orange (OB) fruits (barberries). The study was aimed to evaluate the bioaccessibility of the antioxidants and ACE (angiotensin converting enzyme) inhibitory compounds of barberry plants upon their transit through in-vitro digestion. Among barberries, (PB) exhibited the strongest antioxidant activity due to its higher phenolic and flavonoid content. The order of total phenolics and anthocyanins was PB > RB > OB. Chlorogenic acid was the main phenolic compound in all barberries even after in-vitro digestion. All barberries had similar amounts of total carotenoids (4.45 mg beta-carotene/100gDW). After in-vitro digestion, decreasing phenolics, anthocyanins and carotenoids led to a reduced antioxidant activity. Anthocyanins were found the most sensitive compounds in-vitro digestion. In terms of ACE inhibition activity, only RB exhibited ACE inhibition before (73.84%) and after (65.51%) in-vitro digestion. No ACE inhibition activity was detected at all in RB and OB samples. Leaves and branches of Berberis had also over 50% ACE inhibitory activity. To our knowledge, this is the first study on the carotenoids of barberry and the effect of in-vitro digestion on its bioactive compounds and ACE inhibitors.
