dehydrocorydaline/corydalis solida

Dehydrocorydaline, an active principle of Corydalis bulbosa alkaloids, in concentrations of 10(-5) M to 5 x 10(-5)M inhibited relaxation and the concomitant release of (3H)-noradrenaline caused by 10(-4)M nicotine and electrical perivascular nerve stimulation in the taenia caecum of guinea pig. The

Dehydrocorydaline, an alkaloid from Corydalis bulbosa possessing anti-ulceric activity, was labeled by methyl-14C at position 13, and its disposition and metabolism were studied in mice and rats after oral (50 mg/kg) or intravenous (6.8 mg/kg) administration. Blood levels were as low as 0.5 (mice)
