In Vivo：
Mice（5 weeks old，25±2 g, SPF grade，female KM Mice；200 mg per kg body weight TP; Oral）：
After one week of acclimatization, the mice were randomly divided into 7 groups (n = 30 per group) according to body weight: normal group (N), model group (M), HCP group, MCP group, LCP group, TP group and CP group. The normal and model groups were orally administered with 0.4 mL normal saline daily. For the HCP, MCP, LCP TP and CP groups, identical doses (200 mg per kg body weight) were dissolved in 0.4 mL normal saline and given to each group daily. All experimental animals were fed the control diet (AIN-93G). The dorsal skin of the mice was denuded using 6% sulfureted sodium to form a hairless region of approximately 9 cm2 (3 cm×3 cm) once every 3 days before UV irradiation. All mice except the N group were exposed to UV irradiation in a lamp box which contained 3 UVA lamps (40 W, wavelength of 320–400 nm, peak at 365 nm) and 1 UVB lamp (40 W, wavelength of 290–320 nm, peak at 297 nm). The distance from the lamps to the animals’ backs was 40 cm. The mice were irradiated for 3 consecutive days and 3 hours per day, except for the N group. The body weights were measured weekly. In the 2-week experimental period, 10 mice of each group were deprived of food for 12 h but allowed free access to water and sacrificed at weeks 0, 1 and 2. The serum and dorsal skin were quickly collected and stored at ?80 ℃ until analysis.
