Question:
The swelling index of a crude drug is used to evaluate the ____.
The swelling index of a crude drug is used to evaluate the ____.
Show Hint
Swelling index = mucilage measure—used in assessing drugs like isabgol and linseed.
Updated On: Jun 16, 2025
- presence of alkaloids
- moisture content
- mucilage content
- presence of volatile oils
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The swelling index is an important parameter used to assess the mucilage content of a crude drug. Mucilage absorbs water and swells, hence this index reflects the amount of mucilage present—important for quality control of demulcent drugs.
