It may be obtained from the alcoholic extract of the residue from which the convallamarin has been removed with water. The alcoholic solution is treated with lead acetate, the filtrate freed from lead by hydrogen sulfide, and crystallised by concentration. An aqueous solution froths like soap and water when shaken. By long boiling with diluted acids it is split up into glucose and convallaretin.

It is probably a mixture of convallamarin, convallamaretin and convallatoxin.{{cite journal |last1=Elderfield |first1=Robert C. |title=The Chemistry of the Cardiac Glycosides. |journal=Chemical Reviews |date=1 October 1935 |volume=17 |issue=2 |pages=187–249 |doi=10.1021/cr60057a003}}
