摘要: This study was carried out to explore the mechanism underlying antidiarrheal and antispasmodic activities of Vincetoxicum stocksii . The crude extract V. provided 12-24% protection from castor oil-induced diarrhea at dose 300-1,000 mg/kg, similar loperamide. In isolated rabbit jejunum preparations, caused inhibition spontaneous high K + (80 mM)-induced contractions, with respective EC 50 values 2.53 (1.65-3.90) 0.95 mg/mL (0.63-1.42), that by verapamil, suggesting calcium channel blocking  effect. Loperamide -induced contraction, 8.59 (6.33-10.11) 9.12 µM (7.33-12.81). blocking activity further confirmed when pretreatment tissues (1-3 mg/mL) a rightward displacement Ca ++ concentrations response curves, produced verapamil; constructed in free medium. These data indicate contains constituents may possibly explain its medicinal use hyperactive states gut, such as, spasms.
