Terminalia Macroptera
''Terminalia macroptera'' is a species of flowering plant in the Combretaceae known by the Hausa common name ''kwandari''. It is native to Africa, where it can be found in Benin, Burkina Faso, Ghana, Senegal, Sudan, Uganda, and Nigeria. This species is used medicinally in several African countries. It is used to treat infectious diseases, tuberculosis, hepatitis, and dysentery. Extracts of the plant have shown activity against ''Helicobacter pylori'' and '' Neisseria gonorrhoeae''. Parts of the plant are also used to make dye and perfumes. The leaves contain chlorogenic acid, quercetin, isoorientin, the ellagitannins chebulagic acid, chebulinic acid, punicalagin Punicalagin is an ellagitannin, a type of phenolic compound. It is found as alpha and beta isomers in pomegranates (''Punica granatum''), ''Terminalia catappa'', ''Terminalia myriocarpa'', and in ''Combretum molle'', the velvet bushwillow, a plant ..., and terflavin A, gallic and ellagic acids.

Jean Baptiste Antoine Guillemin
Jean Baptiste Antoine Guillemin (20 January 1796 in Pouilly-sur-Saône – 15 January 1842 in Montpellier) was a French botanist. He studied at the municipal college in Seurre, where he was considered one of the most distinguished pupils. Upon leaving school he was placed with a lawyer. He worked there for eighteen months, but his interest in chemistry and desire to obtain a commission as a military pharmacist, at a time when it was difficult to avoid conscription, caused him to abandon the study of law. In 1812, he was apprenticed to a pharmacist in Dijon. After two years in that city, he went to Geneva, where he studied with Jean Pierre Étienne Vaucher (1763–1841) and Augustin Pyramus de Candolle (1778–1841). One day, while collecting plants in the Alps, he fell and broke his right arm. The injury was slow to heal, and the accident left him with permanent stiffness in the elbow joint. In 1820 he relocated to Paris, where he became curator of the herbarium and library o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicobacter Pylori
''Helicobacter pylori'', previously known as ''Campylobacter pylori'', is a gram-negative, microaerophilic, spiral (helical) bacterium usually found in the stomach. Its helical shape (from which the genus name, helicobacter, derives) is thought to have evolved in order to penetrate the mucoid lining of the stomach and thereby establish infection. The bacterium was first identified in 1982 by the Australian doctors Barry Marshall and Robin Warren. ''H. pylori'' has been associated with cancer of the mucosa-associated lymphoid tissue in the stomach, esophagus, colon, rectum, or tissues around the eye (termed extranodal marginal zone B-cell lymphoma of the cited organ), and of lymphoid tissue in the stomach (termed diffuse large B-cell lymphoma). ''H. pylori'' infection usually has no symptoms but sometimes causes gastritis (stomach inflammation) or ulcers of the stomach or first part of the small intestine. The infection is also associated with the development of cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminalia (plant)
''Terminalia'' is a genus of large trees of the flowering plant family Combretaceae, comprising nearly 300 species distributed in tropical regions of the world. The genus name derives from the Latin word ''terminus'', referring to the fact that the leaves appear at the very tips of the shoots. Selected species There are 282 accepted ''Terminalia'' species as of April 2021 according to Plants of the World Online. Selected species include: *'' Terminalia acuminata'' (Fr. Allem.) Eichl. *'' Terminalia albida'' Scott-Elliot *''Terminalia amazonia'' (J.F.Gmel.)

Punicalagin
Punicalagin is an ellagitannin, a type of phenolic compound. It is found as alpha and beta isomers in pomegranates (''Punica granatum''), ''Terminalia catappa'', ''Terminalia myriocarpa'', and in ''Combretum molle'', the velvet bushwillow, a plant species found in South Africa. These three genera are all Myrtales and the last two are both Combretaceae. Research Punicalagins are water-soluble and hydrolyze into smaller phenolic compounds, such as ellagic acid. There were no toxic effects in rats on a 6% diet of punicalagins for 37 days. In laboratory research, punicalagins had carbonic anhydrase inhibitor Carbonic anhydrase inhibitors are a class of pharmaceuticals that suppress the activity of carbonic anhydrase.

Chebulagic Acid
Chebulagic acid is a benzopyran tannin and an antioxidant that has many potential uses in medicine. It has been found to be immunosuppressive, hepatoprotective, and a potent alpha-glucosidase inhibitor, a human gut enzyme useful in diabetic studies. It has been shown to be active against ''Staphylococcus aureus'' and ''Candida albicans''. It is found in the plants ''Terminalia chebula'', '' T. citrina'' and '' T. catappa''. It is formed from geraniin through a glutathione Glutathione (GSH, ) is an antioxidant in plants, animals, fungi, and some bacteria and archaea.

Perfume
Perfume (, ; french: parfum) is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory." Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics. History The word ''perfume'' derives from the Latin ''perfumare'', meaning "to smoke through". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
