Antioxidant and Antitumor Effect of Different Fractions of Ethyl Acetate Part from Elaeagnus angustifolia L.

摘要

To determine antitumor and antioxidant activities of the different fractions of ethyl acetate of Elaeagnus angustifolia L. extract, the MTT assay, the DPPH scavenging assay and the reducing power method were used. The results showed that as the concentration and the polarity were increasing, the antioxidant activity of the different fractions of ethyl acetate of Elaeagnus angustifolia L. extract was increased. The DPPH scavenging of the E and F fractions was 94.9%. The antitumor assay showed that the different fractions of ethyl acetate of Elaeagnus angustifolia L. exhibited the inhibition of the in vitro cultured Hela cell proliferation properties. During the first 48 h, there was a dependant relation of inhibition effect and the concentration and the polarity. The higher the concentration and the polarity, the stronger the inhibition effect was. The inhibition rate was 74.34% when the concentration of F faction was 2.5 mg/mL.
