- Raymond's
- Shinoda
- Kedde's
- Killer Kiliani
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Cardiac glycosides (like Digitoxin) contain unique 2,6-deoxy sugars such as digitoxose.
Step 2: Meaning
Specific chemical tests target either the sugar part or the lactone ring of the glycoside.
Step 3: Analysis
Raymond's, Kedde's, and Baljet's tests identify the unsaturated lactone ring. The Keller-Kiliani test specifically detects the presence of deoxy sugars, yielding a reddish-brown ring that turns blue-green.
Step 4: Conclusion
Therefore, the Keller-Kiliani test is the standard for identifying deoxy sugars in cardiac glycosides.
Final Answer: (D)
