Abstract:
OBJECTIVE To optimize th e p rocessing technology of Portulaca oleracea charcoal，and to investigate its improvement effect on the symptom of hemorrhoid model rats. METHODS The effects of roasting temperature ，dosage and roasting time on the processing technology of P. oleracea charcoal were investigated with Box-Behnken response surface methodology using comprehensive score of tannin content ，water-soluble extract content and appearance properties as the index. The optimal process parameters are selected and verified. The hemorrhoid model rats were treated with P. oleracea charcoal（0.8 g/mL）prepared by the optimal processing technology ，once a day ，for 11 days. After last medication ，the perianal pathological score of hemorrhoid model rats were performed ；serum levels of tumor necrosis factor α（TNF-α），interleukin 6（IL-6）and IL- 1β were detected. RESULTS The optimal processing technology of P. oleracea charcoal included roasting temperature of 200 ℃， dosage of 150 g and roasting time of 14 min. Results of validation test showed that the comprehensive score of P. oleracea charcoal was 92.57，and relative error of it with predicted value （96.59）was －4.13％. External use of P. oleracea charcoal 0.8 g/mL prepared by the optimal processing technology could significantly promote the wound healing of hemorrhoid model rats ，reduced the amount of exudate ，and decreased the levels of TNF-α，IL-6 and IL-β in serum. CONCLUSIONS The optimized processing technology of P. oleracea charcoal is feasible. P. oleracea charcoal prepared by the optimized processing technology has good curative effect on the symptom of hemorrhoid model rats.
