Question:
Which of the following tests of aloe is based upon fluorescence
Which of the following tests of aloe is based upon fluorescence
Show Hint
Schoenteten = "Shine" (Green Fluorescence).
Updated On: May 25, 2026
- Cupraloin test
- Borntrager's test
- Bromine test
- Schoenteten test
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Aloe contains C-glycosides like barbaloin, which require specific chemical tests for identification.
Step 2: Meaning
Fluorescence tests involve observing a specific color glow under UV or visible light after chemical treatment.
Step 3: Analysis
The Schoenteten (or Schouteten) test involves adding borax to an aqueous solution of aloe, which produces a green fluorescence. Borntrager's test is for free anthraquinones (pink color), not fluorescence.
Step 4: Conclusion
The Schoenteten test is the standard fluorescence-based test for aloe. Final Answer: (D)
