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.
A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill
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.
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).
In petroleum science, reservoir fluids are the fluids mixture contained within the petroleum reservoir which technically are placed in the reservoir rock. Reservoir fluids normally include liquid hydrocarbon (mainly Crude oil), aqueous solutions with dissolved salt, hydrocarbon and non-hydrocarbon gases such as methane and hydrogen sulfide [1] respectively.
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.
Mineral oil is used as a laxative to alleviate constipation by retaining water in stool and the intestines. [11] Although generally considered safe, as noted above, there is a concern of mist inhalation leading to serious health conditions such as pneumonia. [12] Mineral oil can be administered either orally [13] or rectally. [14]
Mineral oil is organic. However, it is classified as "mineral oil" instead of as "organic oil" because its organic origin is remote (and was unknown at the time of its discovery), and because it is obtained in the vicinity of rocks, underground traps, and sands. Mineral oil also refers to several specific distillates of crude oil. [citation needed]
