Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Chemical tests are used in pharmacognosy for the qualitative identification of plant metabolites.
Step 2: Meaning
The Baljet test is specifically used for cardiac glycosides (cardenolides).
Step 3: Analysis
When a cardenolide reacts with Baljet's reagent (sodium picrate), it produces an orange to red color. Tannins (B) are tested with Ferric chloride; Chlorophyll (C) is identified by its color and fluorescence; Triterpenes (D) are often identified by the Salkowski test.
Step 4: Conclusion
The Baljet test is a confirmatory test for Cardiac Glycosides.
Final Answer: (A)
