背景
苦楝是一种常见的楝科楝属植物,其主要活性成分苦楝素(toosendanin)可作为中药用于驱蛔、抗菌,同时也是一种具有广阔发展前景的杀虫剂,对多种害虫有毒杀作用,主要表现为使虫忌避、拒食;抑制昆虫生长发育、触杀、内吸制毒作用等。川楝子提取物来源于楝科植物川楝Melia toosendan Sieb. et Zucc.的干燥成熟果实。冬季果实成熟时采收,除去杂质,干燥。
功效
川楝子提取物具有除湿热,清肝火,止痛,杀虫。治热厥心痛,胁痛,疝痛,虫积腹痛。
苦楝树皮提取物
苦楝素是从天然植物苦楝树皮中分离出来的一种物质,有驱除蛔虫,蛲虫和鞭虫的作用,以对蛔虫的作用最明显。
苦楝的根是苦的,躯干是苦的,枝叶是苦的,而浸透了苦汁的生命却孕育出了清香的花朵。
生物活性
Toosendanin是从杜鹃花果实皮中提取的一种三萜,具有镇痛、杀虫和抗炎作用。
体内研究
Toosendanin (0.5 and 1 mg/kg, Intraperitoneal injection daily for 7 days) alleviates DSS-induced experimental colitis by inhibiting M1 macrophage polarization and regulating NLRP3 inflammasome and Nrf2/HO-1 signaling, and may provide a novel Chinese patent medicine for the treatment of murine colitis.
Animal Model: Forty-eight male C57BL/6 mice weighing 20-22 g.
Dosage: 0.5 and 1 mg/kg.
Administration: Intraperitoneal injection daily for 7 days.
Result: Protected against DSS-induced colitis in mice.
Inhibited the expression of proinflammatory cytokines in DSS-induced UC and improved oxidative stress.

用途
用于含量测定/鉴定/药理实验等。
药理药效:主要用于驱钩虫、蛔虫、蛲虫及混合感染。川楝素是苦楝皮的驱蛔有效成分,它比乙醇提取物的作用强,与山道年相比,作用缓慢而久。川楝素对呼吸中枢有抑制作用。
