Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Essential oils extracted from the heartwood of certain aromatic trees are highly valued in the perfumery, cosmetics, and pharmaceutical industries due to their distinct, long-lasting fragrances.
Step 2: Detailed Explanation:
1. Santalum album (Sandalwood) is a semi-parasitic tree native to the deciduous forests of southern India.
2. The older heartwood of this tree is highly aromatic and contains a rich essential oil.
3. Upon steam distillation, this heartwood yields Sandalwood oil, which has a heavy, warm, sweet, and exceptionally long-lasting woody odor.
4. This oil is characterized by high concentrations of \(\alpha\)- and \(\beta\)-santalol.
5. Other choices yield different types of oils: Cedrus deodara yields cedarwood oil, Pinus roxburghii yields turpentine resin, and Eucalyptus citriodora yields a lemon-scented leaf oil.
Step 3: Final Answer:
The heartwood of Santalum album yields a sweet, long-lasting oil upon distillation.
