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

Question:

Match the plant source (List I) with the corresponding secondary metabolites (List II):

LIST I | LIST II
A. Belladonna | I. Menthol
B. Foxglove | II. Atropine
C. Pacific yew | III. Digitalin
D. Eucalyptus | IV. Taxol

Choose the correct answer from the options given below:

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

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

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

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

Correct Answer:

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

Detailed Explanation:

A. Belladonna – Atropine (II):

• Belladonna (also known as Deadly Nightshade) produces atropine, a tropane alkaloid used in medicine for its anticholinergic properties. Atropine is used to treat bradycardia, as a pre-anesthetic to dry secretions, and in eye exams to dilate pupils.

B. Foxglove – Digitalin (III):

• Foxglove (scientific name Digitalis purpurea) is the source of digitalin, a cardiac glycoside that is used to treat heart conditions such as heart failure and arrhythmias. Digitalin works by increasing the force of heart contractions.

C. Pacific Yew – Taxol (IV):

• Pacific yew (Taxus brevifolia) is known for producing Taxol (also known as paclitaxel), a potent anti-cancer drug. Taxol is used in chemotherapy to treat various cancers, including ovarian, breast, and lung cancers.

D. Eucalyptus – Menthol (I):

• Eucalyptus (Eucalyptus globulus) produces menthol, a compound commonly used for its cooling effect in medicinal products such as balms, cough syrups, and topical ointments.

Conclusion:

The correct pairing of plants with their secondary metabolites is as follows:

• Belladonna produces Atropine.

• Foxglove produces Digitalin.

• Pacific Yew produces Taxol.

• Eucalyptus produces Menthol.

These plants have been historically significant for their medicinal properties, and their secondary metabolites continue to play important roles in modern healthcare.
