7-EthylCamptothecin
7-Ethylcampothecin (7-ECPT) is a derivative from natural campthecin, a cytotoxic quinoline alkaloid originated from camtotheca acuminata or Nothapodytes pittosporoides(Mappia).Camptothecin was discovered in 1966 by M. E. Wall and M. C. Wani in systematic screening of natural products for anticancer drugs.

Natural origins of camptothecin
1. Camptotheca acuminata (Camptotheca, Happy tree), a tree native to Hunan ,Guangxi, Sichuan province of China. Camptotheca acuminata used as a cancer treatment in Traditional Chinese Medicine.Generally, the leaves and the fruits of happy tree are applied for the extraction of camptothecin.
2. Nothapodytes pittosporoides(Mappia), a tree wild spread in Hunan ,Guangxi, Sichuan province of China. The root of the tree is applied for the extraction of campothecin, most of this origin is applied for R&D.
