The chief quinazoline alkaloid vasicine is reported in all parts of the plant, the highest being in inflorescence. It is a bitter bronchodilator, respiratory stimulant, hypotensive, cardiac depressant, uterotonic and abortifacient. An aqueous solution of vasicinone hydrochloride, when studied in mice and dogs, was found to potentiate the bronchodilatory activity of aminophylline, also that of isopre naline. Vasicinone exhibited smooth- muscle-relaxant properties of airways.
Alkaloids present in the plant showed significant protection against allergin-induced bronchial obstruction in guinea pigs.
