Question

The process of placing the powdered solid along with solvent in a closed vessel for about 7 days in called as

• A. Percolation
• B. Decoction
• C. Imbibition
• D. Maceration

Hint:

Maceration = "Marination." Let it soak for 7 days to get the flavor (active drug) out.

Answer 1

The Correct Option is D

Step 1: Concept
Extraction processes are used to separate active medicaments from crude drugs using a solvent (menstruum).

Step 2: Meaning
Maceration is a "soaking" process where the drug and solvent are left in contact for a prolonged period.

Step 3: Analysis
In maceration, the drug is placed in a stoppered container with the whole of the menstruum and allowed to stand for 7 days with occasional shaking. This allows the solvent to penetrate the cells and dissolve the active constituents.

Step 4: Conclusion
This specific 7-day soaking process describes the maceration technique.

Final Answer: (D)
