Antiproliferative activity of three kiwi polyphenol crude extracts on A549 and Hela cells

The three kinds of kiwifruit polyphenol were extracted with 60% ethanol. The supernatants after centrifugation were then individually pooled and condensed using a rotary evaporator.The antiproliferative activity of the kiwi crude extracts on A549 and Hela cell was analyzed by cell morphology analysis, MTT assay and DNA Ladder.The results demonstrated that the Actinidia arguta extract had a higher antiproliferative activity than the other two kinds of Actinidia extracts.Therefore, Actinidia arguta extract could be used as a new cancer inhibitor.The results provided new insight into the health function of fruit and demonstrated that Actinidia extracts potentially had health benefits.
