产品简介:一种从七叶树种子七叶树中分离出来的,对动物急性炎症有积极作用。Escin IIa 对乙醇诱导的胃粘膜损伤有明显的保护作用。
体内研究:Escins Ia, Ib, IIa, and IIb (50-200 mg/kg) inhibits the increase of vascular permeability induced by both acetic acid in mice and histamine in rats. Escins Ib, IIa, and IIb (50-200 mg/kg) also inhibit that induced by serotonin in rats, but escin Ia didn't. Escins Ia, Ib, IIa, and IIb (200 mg/kg) inhibit the hind paw edema induced by carrageenin at the first phase in rats. Escin Ia (200 mg/kg) and escins Ib, IIa, and IIb (50-200 mg/kg) inhibit the scratching behavior induced by compound 48/80 in mice, but escin Ia was weakest. Escin IIa (10-50 mg/kg;p.o.;) potently inhibits ethanol-induced gastric mucosal lesions.
