Antibiotic properties of Allium species is due to

Options

A. Allicin
B. Diallylsulphide
C. `H_(2)S`
D. Both A and B.

Answer

To answer the question regarding the antibiotic properties of Allium species, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Allium Species**:
- Allium species include plants such as garlic and onions. They are known for their various health benefits, including antibiotic properties.

2. **Identifying the Compounds**:
- The question provides several options: allicin, diallyl sulfide, H2S, or both A and B. We need to identify which of these compounds is responsible for the antibiotic properties.

3. **Researching Allicin**:
- Allicin is a compound that is formed when garlic is crushed or chopped. It is known for its antimicrobial properties and is often cited as a key component in the health benefits of garlic.

4. **Researching Diallyl Sulfide**:
- Diallyl sulfide is another organosulfur compound found in garlic and onions. It has been studied for its potential health benefits, including its antibiotic properties.

5. **Comparing the Options**:
- Both allicin and diallyl sulfide have been shown to possess antibiotic properties. However, the question asks specifically about the antibiotic properties of Allium species.

6. **Conclusion**:
- While both compounds contribute to the antibiotic properties, the most significant compound associated with the antibiotic effects in Allium species is diallyl sulfide. Thus, the answer is diallyl sulfide.

### Final Answer:
The antibiotic properties of Allium species are primarily due to **diallyl sulfide**.
