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.
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 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.
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 ...
Urushiol / ʊ ˈ r uː ʃ i. ɒ l / is an oily mixture of organic compounds with allergenic properties found in plants of the family Anacardiaceae, especially Toxicodendron spp. (e.g., poison oak, Chinese lacquer tree, poison ivy, poison sumac), Comocladia spp. (maidenplums), Metopium spp.
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.
Industrial machines for extracting oil mechanically are call expellers. Many expellers add heat and pressure, in order to increase the amount of oil extracted. If the temperature does not exceed 120 °F, the oil can be called "cold-pressed". [3] In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as ...
The essential oil of thyme subspecies contains between 5% and 75% of carvacrol, while Satureja (savory) subspecies have a content between 1% and 45%. [6] Origanum majorana (marjoram) and Dittany of Crete are rich in carvacrol, 50% and 60–80% respectively. [7] It is also found in tequila [8] and Lippia graveolens (Mexican oregano) in the ...
