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.
Oil bodies are the organelle that has evolved to hold triglycerides in plant cells. They are therefore the principal store of chemical energy in oleaginous seeds. The structure and composition of plant seed oil bodies has been the subject of research from at least as far back as the 1980s, with several papers published in the 80s and 90s.
There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
As Bryan E. Cummings and Michael S. Waring, the authors of the Drexel study, found, you would need 10–100 plants per square meter to clear the air in the way the NASA study reported.
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).
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 .
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.
