Study on Antioxidant Activities from Different Parts of Siraitia grosvenorii
Objective: The antioxidant activity of siraitia grosvenorii leaves
stems and fruits was studied by 2
2-diphenyl-l-picrylhydrazyl (DPPH) method. Method: The stems
leaves and fruits of siraitia grosvenorii were extracted with ethanol by ultrasonic extraction
and the DPPH clearing rate of different extracts was determined by spectrophotometry. Result: Half clearance of scavenging effect on radical DPPH by three parts including stem
leaf and fruit from Siraitia grosvenorii
i.e.IC50
was 0.756
0.119
0.358 g ·L-1 respectively. Conclusion: Extracts from three parts of Siraitia grosvenorii have antioxidant activity.The leaf owns the strongest antioxidant capacity.
