Convallarin
Encyclopedia
Convallarin is a crystalline glucoside
extracted from Convallaria majalis
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 sugar
and convallaretin.
Glucoside
A glucoside is a glycoside that is derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes....
