Solution: Matching Crude Drugs with Active Constituents
This question requires matching specific crude drugs from List I with their primary active constituents found in List II.
1. Sandalwood (A) and Santalols (IV)
Sandalwood oil, derived from trees of the genus Santalum, is primarily known for its rich aroma. The main chemical components responsible for this scent are a group of sesquiterpene alcohols called Santalols.
2. Rosemerry (B) and Borneol (III)
Rosemary (Salvia rosmarinus) essential oil contains various compounds. While cineole and camphor are often highlighted, Borneol is also a known constituent contributing to its complex aroma profile. This matches crude drug B with active constituent III.
3. Dill (C) and Carvone (II)
Dill (Anethum graveolens), particularly its seeds and herb, contains essential oils. A significant component of dill oil is Carvone, which is also found in spearmint and caraway, contributing to its characteristic flavour and scent.
4. Parsley (D) and Apiole (I)
Parsley (Petroselinum crispum) contains essential oils, with Apiole being a notable phenylpropene constituent, especially concentrated in the seeds and roots. It is responsible for some of parsley's distinct properties.
Summary of Matches
Based on the established chemical constituents:
- Crude Drug A (Sandalwood) matches Active Constituent IV (Santalols).
- Crude Drug B (Rosemerry) matches Active Constituent III (Borneol).
- Crude Drug C (Dill) matches Active Constituent II (Carvone).
- Crude Drug D (Parsley) matches Active Constituent I (Apiole).
Conclusion
The correct combination aligning these matches is A-IV, B-III, C-II, D-I.
