Radical Scavenging Activity of Oxtropis myriophylla
Objective:To study DPPH and ABTS radical scavenging activities of Oxtropis myriophylla.Method: The anti-oxidant activity of O.myriophylla was measured by DPPH assay and ABTS assay.Furthermore
the AB-8 macroporous absorbent resincolumn chromatography with gradient elution(aqueous solution
50% and 90% ethanol solution)were used.Result:50% ethanol extract from O.myriophylla in the capability of scavenging DPPH and ABTS free radicals was much stronger than any other fractions
which is a trifle stronger than ascorbic acid.In addition
the active ingredient was screened effectively by the column chromatography method.Conclusion:50% ethanol extract from O.myriophylla in the capability of scavenging DPPH and ABTS free radicals was much stronger than any other fractions
which is a trifle stronger than ascorbic acid.In addition
the active ingredient was screened effectively by the column chromatography method.Conclusion: The 50% ethanol extracts exhibited strong scavenging capacity of free radical.
