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.
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.
Naturally occurring phenethylamines are organic compounds which may be thought of as being derived from phenethylamine itself that are found in living organisms. Tyramine is a phenethylamine that occurs widely in plants [ 1 ] and animals , and is metabolized by various enzymes , including monoamine oxidases .
Considered promising as a food or fuel oil. [89] Grape seed oil, a cooking and salad oil, also sprayed on raisins to help them retain their flavor. [90] Hemp oil, a high quality food oil [91] also used to make paints, varnishes, resins and soft soaps. [92] Kapok seed oil, from the seeds of Ceiba pentandra, used as an edible oil, and in soap ...
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).
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 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, which are the most medically useful Vinca alkaloids.

Persin is an oil-soluble compound structurally similar to a fatty acid, a colourless oil, and it leaches into the body of the fruit from the seeds. The relatively low concentrations of persin in the ripe pulp of the avocado fruit is generally considered harmless to humans. Negative effects in humans are primarily in allergic individuals. When ...
