生物活性
Escin IIa 是從七葉樹(shù)種子七葉樹(shù)中分離出來(lái)的，對(duì)動(dòng)物急性炎癥有積極作用。Escin IIa 對(duì)乙醇誘導(dǎo)的胃粘膜損傷有明顯的保護(hù)作用。體內(nèi)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.
