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.
Vincamine is a monoterpenoid indole alkaloid found in the leaves of Vinca minor (lesser periwinkle), comprising about 25–65% of its indole alkaloids by weight. It can also be synthesized from related alkaloids. [1]
The newer semi-synthetic chemotherapeutic agent vinorelbine, used in the treatment of non-small-cell lung cancer, [27] [30] can be prepared either from vindoline and catharanthine [27] [31] or from the vinca alkaloid leurosine, [32] in both cases via anhydrovinblastine. [31] The insulin-stimulating vincoline has been isolated from the plant ...
Catharanthus roseus, known formerly as Vinca rosea, is a main source of vinca alkaloids, now sometimes called catharanthus alkaloids. The plant produces about 130 of these compounds, including vinblastine and vincristine, two drugs used to treat cancer. [8] [9] [10] [11]
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).

Vinca (/ ˈ v ɪ ŋ k ə /; [2] Latin: vincire "to bind, fetter") is an Old World genus of flowering plants in the family Apocynaceae, The English name periwinkle is shared with the related genus Catharanthus (and with the mollusc Littorina littorea). Some Vinca species are cultivated but have also spread invasively.
Vindesine, also termed Eldisine, is a semisynthetic vinca alkaloid derived from the flowering plant Catharanthus roseus. [1] Like the natural (e.g. vinblastine and vincristine) and semisynthetic vinca alkaloids (e.g. vinorelbine and vinflunine) derived from this plant, vindesine is an inhibitor of mitosis that is used as a chemotherapy drug. [2]
Vinpocetine (ethyl apovincaminate) is a synthetic derivative of the vinca alkaloid vincamine, differing by the removal of a hydroxyl group and by being the ethyl rather than the methyl ester of the underlying carboxylic acid. Vincamine is extracted from either the seeds of Voacanga africana or the leaves of Vinca minor (lesser periwinkle).
