【摘要】 雷酚内酯（triptophenolideTN）是由雷公藤醋酸乙酯提取物中分离的一种白色片状结晶。口服TN能显著抑制二甲苯及巴豆油所致急性炎症；且可使小鼠肾上腺VitC含量明显降低。TN可明显抑制DNCB和BSA诱导的迟发超敏反应；并可使大、小鼠外周血ANAE＋淋巴细胞明显减少，显示TN对T淋巴细胞的免疫功能有抑制作用，TN还能显著提高大、小鼠血清总补体含量及抑制循环中1gG的形成量。其对小鼠腹腔Mφ吞噬功能呈现小剂量促进、大剂量抑制的双向作用。更多还原

【Abstract】 Triptophenolide (TN) is a colorless crystalline plate isolated from ethyl acetate extracts of Tripterygium wilfordii. It can obviously inhibit the edema caused by xylol and mixture croton oil; and decrease the concentration of Vitamin C in the adrenal gland of mice.TN can remarkably inhibit the delayed type hypersensitivity (DTH) reaction induced by DNCB and BSA; and diminished the peripheral blood ANAE+lymphocytes in rats and micc.Moreover, TN can dramatically increase the amount of total serum complement and significautly decrcase the serum antibody products (1gG ) of rats and mice. The phagocytosis of perioneal exudate macrophages in mice present double effects in vitro. TN can promote the phagocytosis of macrophages at the small dosage, but at larger dosage, it showed inhibition.The results mentioned above showed that triptophenolide may be one of the main effective component of T.wilfordii for treating auto-immune diseases.更多还原
