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]

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).
The alkaloids are a large group of natural products which are classified according to the part-structure which members of a particular group contain. Akuammicine is a monoterpene indole alkaloid of the Vinca sub-group which shares a common biosynthesis with other members, namely that they are derived from strictosidine.
Vinblastine is a vinca alkaloid [9] [2] [10] and a chemical analogue of vincristine. [11] [12] It binds tubulin, thereby inhibiting the assembly of microtubules. [13]Vinblastine treatment causes M phase specific cell cycle arrest by disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore, each of which are necessary for the separation of chromosomes ...
The Valencia diet emphasizes fruits, vegetables, and plant-based proteins—a meal plan that Dr. Laing generally approves of, noting that many adults in the U.S. don’t consume enough of these foods.
Vincaminol (C 20 H 26 N 2 O 2) is a chemical that is a part of the Vinca alkaloid group, which were discovered in the 1950s by a Canadian scientist and are derived from Vinca minor (periwinkle). [ 1 ] [ 2 ] Vincaminol is not as well known as some of the other Vinca alkaloids such as vinblastine , vinorelbine , vincristine , and vindesine ...
