Question

Match List I with List II 

 

• A. A-II, B-I, C-III, D-IV
• B. A-I, B-III, C-IV, D-II
• C. A-III, B-IV, C-II, D-I
• D. A-IV, B-III, C-I, D-II

Hint:

To remember:
- Lard is animal fat (D-IV).
- Catechu is rich in astringent tannins (B-I).
- Podophyllum is a classic resin source (A-II).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Pharmacognosy involves the study of crude drugs of natural (plant and animal) origin, classified based on their physical and chemical properties into resins, tannins, gums, and lipids.

Step 2: Detailed Explanation:
Let us correlate each material with its correct pharmacognostic category:
- A. Resins: Amorphous solid or semi-solid organic substances produced by plants.
Podophyllum is a major source of active therapeutic resins (podophyllin) used as a purgative.
Thus, A matches with II.
- B. Tannins: Complex polyphenolic compounds capable of precipitating proteins, often used as astringents.
Catechu (from Acacia catechu) is exceptionally rich in condensed tannins.
Thus, B matches with I.
- C. Gums Mucilages: Polysaccharide complexes that are soluble or swell in water to form viscous colloids.
Agar is a hydrocolloid polysaccharide obtained from marine red algae.
Thus, C matches with III.
- D. Fats: Solid or semi-solid esters of fatty acids with glycerol.
Lard is purified fat obtained from the abdomen of the pig (*Sus scrofa*).
Thus, D matches with IV.

Step 3: Final Answer:
Matching these categories gives the sequence A-II, B-I, C-III, D-IV, which is option (A).
