Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Digitoxin is a powerful cardiac glycoside used in veterinary and human medicine to manage congestive heart failure and certain cardiac arrhythmias.
It is derived from natural plant sources.
Detailed Explanation:
Let us review the pharmacological products obtained from the plants listed in the options:
- Snake root (Rauvolfia serpentina): The source of reserpine, an antipsychotic and antihypertensive drug.
- Foxglove (Digitalis purpurea): The primary botanical source of cardiac glycosides, specifically digitoxin and digoxin. These compounds inhibit the $Na^+/K^+$-ATPase pump to increase cardiac contractility.
- Nux vomica (Strychnos nux-vomica): The source of strychnine, a highly toxic spinal stimulant and pesticide.
- Yew tree (Taxus spp.): The source of paclitaxel (Taxol), a chemotherapeutic agent used in oncology.
Step 2: Final Answer:
The main source of Digitoxin is Foxglove, which corresponds to Option (B).
