Which test is specially used for localisation of cardiac glycosides in the crude drug?
A
Kalanj test
B
Baljet test
C
Molisch test
D
Mayer test
Correct Option:
B
Explanation
The Baljet test is particularly useful for detecting/localising cardiac glycosides. A section of a glycoside-containing drug such as Digitalis is treated with sodium picrate, producing a yellow to orange colour due to the unsaturated lactone portion of cardiac glycosides. Molisch tests carbohydrates, while Mayer’s reagent is associated with alkaloids.
