Abstract
Cinchonine and dihydrocinchonine have been found as minor alkaloids in the leaves of Anthocephalus chinensis grown in India. Quinoline alkaloids have not so far been found in the genus Anthocephalus. Their occurrence within this genus shows that it has a special place within the tribe Naucleeae and that there exists a chemical relationship with the genus Cinchona of the tribe Cinchoneae.
