D.	Codeine	IV.	Digitalis lanata

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is A

The question provides a list of compounds and a list of plant species, and asks us to match each compound with the corresponding plant species from which it is primarily derived. Let's match them one by one based on pharmacognosic knowledge:

1. Cardinolides: These are cardiac glycosides. A well-known plant source for these compounds is Digitalis lanata, which is used to produce medications like digoxin that affect heart functions. Hence, the match is A-IV.
2. Rutin: Rutin is a type of flavonoid. It is commonly found in Ruta graveolens and also in other plants like buckwheat. Therefore, the correct match is B-I.
3. Ajamalicine: This is an alkaloid found in Catharanthus roseus (also known as Madagascar periwinkle). This plant is significant for its medicinal alkaloids used in cancer treatment. Thus, the correct match is C-II.
4. Codeine: This is a well-known opiate, derived from the opium poppy Papaver somnifera. Therefore, the match is D-III.

Combining these findings, the correct answer choice is: A-IV, B-I, C-II, D-III.
