Options

A. Abrin + Ricin
B. Vinblastin + Curcumin
C. Anthocyanine
D. Ricin + Glucosinolates

Answer

To determine which secondary metabolites are used as drugs, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Secondary Metabolites**:
- The question lists four options:
1. Abrin and Ricin
2. Vinblastine and Curcumin
3. Anthocyanin
4. Resin and Glucosinolates

2. **Analyze Each Option**:
- **Option 1: Abrin and Ricin**:
- Both are toxic proteins derived from the seeds of the Abrus precatorius and Ricinus communis plants, respectively. They are not used as drugs due to their high toxicity.
- **Option 2: Vinblastine and Curcumin**:
- **Vinblastine**: An alkaloid used as an anti-cancer drug, effective in treating various types of cancers.

- **Option 3: Anthocyanin**:
- A type of flavonoid pigment found in many plants, responsible for red, purple, and blue colors. While it has antioxidant properties, it is not primarily used as a drug.
- **Option 4: Resin and Glucosinolates**:
- **Resin**: Generally used in traditional medicine but not specifically classified as a drug.
- **Glucosinolates**: Compounds found in cruciferous vegetables, they have health benefits but are not used directly as drugs.

3. **Conclusion**:
- After analyzing the options, the only pair that includes secondary metabolites used as drugs is **Vinblastine and Curcumin**. Therefore, the correct answer is:

**Option 2: Vinblastine and Curcumin.**
