Pyrethrin is extracted from which type of source?

• A. Leaves
• B. Roots
• C. Flowers
• D. Bark

Answer: (C)

Pyrethrin is a natural insecticide that is extracted from the flowers of the chrysanthemum plant, specifically from species such as Chrysanthemum cinerariifolium and Chrysanthemum coccineum. The active compounds in pyrethrin are primarily found in the flower heads, where they occur in high concentrations. This makes the flowers the correct source for pyrethrin extraction. Alternative plant parts, such as leaves, roots, or bark, do not contain the same levels of these active compounds required for pyrethrin production. Therefore, the choice related to flowers best reflects the origin of this insecticide, highlighting the importance of knowing specific botanical sources when working with natural pesticides.
