Catharanthus is a genus of flowering plants in the family Apocynaceae.Like the genus Vinca, they are known commonly as periwinkles. [3] There are eight known species. Seven are endemic to Madagascar, [4] though one, C. roseus, is widely naturalized around the world.
The diverse flora of Madagascar holds potential for natural product research and drug production on an industrial scale; the Madagascar periwinkle (Cataranthus roseus), a source of alkaloids used in the treatment of different cancers, is a famous example.
Catharanthus lanceus, the lance-leaf periwinkle, grows as a perennial herb up to 1 metre (3 ft) tall. Its fragrant flowers feature white or cream corolla lobes turning pink, reddish-violet or pink-magenta. Its habitat is on volcanic or burned soil, hillside rocks and in open woodland on ridges.
Vinca alkaloids were originally manufactured by extracting them from Catharanthus roseus (Madagascar Periwinkle). [1] Podophyllum spp. Two chemotherapy drugs, etoposide and teniposide, are synthetic chemical compounds similar in chemical structure to the toxin podophyllotoxin which is found in Podophyllum peltatum (May Apple).

The Madagascan periwinkle Catharanthus roseus L. is the source for a number of important natural products, [1] including catharanthine and vindoline [2] and the vinca alkaloids it produces from them: leurosine and the chemotherapy agents vinblastine [3] and vincristine, [4] all of which can be obtained from the plant.
The drugs vinblastine and vincristine, used to treat Hodgkin's disease, leukemia and other cancers, were derived from the Madagascar periwinkle. [20] The traveler's palm, known locally as ravinala [21] and endemic to the eastern rain forests, [22] is highly iconic of Madagascar and is featured in the national emblem as well as the Air ...
