摘　　要：Houttuynia cordata flavonoid and Sophora japonica L. polysaccharide were investigated to develop anti-UV sun-screening agent through UV wavelength scanning spectrum, antioxidant ability and cell viability after UVB irradiation. The results showed that the extracts had strong UVA and UVB absorption ability and hydroxyl free radical scavenging ability. The S. japonica L. polysaccharide showed strong anti-UVB irradiation ability according to the cell viability experiment. It suggests that the H. cordata flavonoid and S. japonica L. polysaccharide could be combined as a candidate of anti-UV sun-screening supplement and compensate for the shortcomings of chemical sunscreens against UVA ray.Houttuynia cordata flavonoid and Sophora japonica L. polysaccharide were investigated to develop anti-UV sun-screening agent through UV wavelength scanning spectrum, antioxidant ability and cell viability after UVB irradiation.
