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.
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 Eli Lilly natural products group found that alkaloids of the Madagascar periwinkle (Vinca rosea), originally discovered in a screen for anti-diabetic drugs, blocked proliferation of tumour cells. The antitumour effect of the vinca alkaloids (e.g. vincristine ) was later shown to be due to their ability to inhibit microtubule polymerization ...
There are many plants in Africa that can be used for medicinal purposes and more than 4000 are used for this purpose in the tropical regions of Africa. [16] Medicinal plants are used in the treatments of many diseases and illnesses, the uses and effects of which are of growing interest to Western societies.
Vinblastine—used to treat leukaemia, Hodgkin's lymphoma, non-small cell lung cancer, breast cancer and testicular cancer. It is also a component in a large number of chemotherapy regimens. Vinblastine and vincristine were isolated from the Madagascar periwinkle Catharanthus roseus, traditionally used to treat diabetes. In fact it has been ...
Yohimbine should not be confused with yohimbe [4] but often is. [5]Yohimbe is the common English name for the tree species P. johimbe (also called Corynanthe johimbe) and, by extension, the name of a medicinal preparation made from the bark of that tree, sold as an aphrodisiac. [6]
