Cardiac glycosides and Antipyretic Activity

Cardiac glycosides are primarily known for their positive inotropic effects, meaning they increase the strength of heart contractions, not for reducing fever.

Glycosidic Bond Types

Glycosides can form various types of bonds besides O-glycosidic. Other examples include N-glycosidic, S-glycosidic, and C-glycosidic bonds.

Qualitative Tests for Cardiac Glycosides

Baljet's test and Keller Kiliani's test are used to detect the presence of cardiac glycosides in a sample, indicating their presence. These are qualitative tests.

Cardiac Glycosides and Digitalis

Plants belonging to the Digitalis genus, such as foxglove, are a common source of cardiac glycosides. These plants have been used medicinally.

Glycosidic Bond Variety

In a dry test, a glycoside can be linked by an O-glycosidic bond, which is the most common, but also by N-, S-, or C-glycosidic bonds.
