Natural Plant Extract Camptotheca Acuminata Extract Camptothecin 98%

Camptotheca acuminata Extract and Camptothecin represent a landmark case of drug discovery from a plant source—a powerful but initially toxic natural product that became the foundation for critical modern cancer therapies.

Here’s a detailed, structured breakdown:

1. The Source: Camptotheca acuminata (The Happy Tree)
What it is: A deciduous tree native to southern China and Tibet. Its Chinese name, Xǐshù, means "Happy Tree" or "Cancer Tree," hinting at its traditional medicinal use for cancers, psoriasis, and liver diseases.

The Extract: The bark, wood, and fruit of the tree contain a cocktail of alkaloids, the most significant of which is camptothecin.

2. The Star Compound: Camptothecin (CPT)
Classification: A potent, pentacyclic quinoline alkaloid. It is a cytotoxic compound, meaning it kills cells, especially rapidly dividing ones like cancer cells.

Discovery: Isolated in 1966 by Monroe E. Wall and Mansukh C. Wani (who also discovered paclitaxel/Taxol). Its unique mechanism generated immense excitement.
