Objective: To study the antioxidant activity of (6R
7S
8S)-7α-[(β-glucopyranosyl)oxy] lyoniresinol from Tarphochlamys affinis. Method: With microtitration assay and ultra-violet-visible (UV-Vis) spectrophotometry
effect of (6R
7S
8S)-7α-[(β-glucopyranosyl)oxy] lyoniresinol on clearance rate of 1
1-diphenyl-2-picrylhydrazyl radical 2
2-diphenyl-1-(2
4
6 trinitrophenyl) hydrazyl(DPPH·)
hydroxyl radical·OH and superoxide anion O-2· were determined with Vitamin C(Vc) as positive control. Result: (6R
7S
8S)-7α-[(β-glucopyranosyl)oxy] lyoniresinol had scavenging capability against DPPH·(half clearance rate concentration IC50 8.11 mg·L-1)
·OH(IC50 21.61 mg·L-1) and O-2·(IC50 10.30 mg·L-1) radicals and has a good dose-responses with the concentration. Conclusion: (6R
7S
8S)-7α-[(β-glucopyranosyl)oxy] lyoniresinol has the stronger antioxidant activity.
