OBJECTIVE: This study aimed to determine the optimal extraction process and
examine whether the combination of Flos Sophorae Immaturus (FSI) and Yupingfeng
san (YPS) has a synergistic effect on free radical scavenging capacity. DESIGN
AND METHODS: The time of immersion and extraction and the ratios
(material/solvent) of the combination of YPS and FSI were optimized on the basis
of polysaccharide and flavonoid yields via orthogonal design. The optimal result
was used in the 1,1-diphenyl-1-picrylhydrazyl (DPPH) assay and animal experiments
to test the antioxidant activity, which is reflected by superoxide dismutase,
malondialdehyde, glutathione peroxidase, and total antioxidant capacity serum
levels. The optimal extraction process was determined using various ingredients
to obtain complex extracts with high active ingredient content and antioxidant
activity. DPPH assay results showed that the optimized ingredients have
antioxidant effects, and the combination had better antioxidation function than
YPS in vitro. The combination also showed synergistic antioxidant activity
compared with YPS in vivo. CONCLUSIONS: The combination of YPS and FSI had a
synergistic antioxidant effect in vitro. The optimized extracts had antioxidant
effects in vivo. These results indicated that YPS could be used with FSI to
improve its antioxidant capacity in the body on the basis of free radical
scavenging capacity.
