Abstract:It has been demonstrated by cytochrome C colorimetry that the Taohong Siwu Decoction(TF) is effective in hy-droxyl radical scavenging.TBA colorimetry has proved that TF is effective in inhibiting lipid peroxidation. As detectedby viscometry hyaluronic acid cleavage induced by hydroxyl radical can be inhibited by TF. It has been demonstratedby SDS-PAGE method that TF is effective in inhibiting collagen crosslinking.
