Kielmeyera Variabilis
''Kielmeyera variabilis'' (malva-do-campo or pau santo) is tree growing to a height of 3–6 meters, found in savannah regions of eastern and central Brazil (the Cerrado). ''K. variabilis'' is traditionally used in folk medicine to treat tropical diseases including schistosomiasis, leishmaniasis, malaria, as well as fungal and bacterial infections.Alves TMA, Silva AF, Brandão M, Grandi TSM, Smânia EF, Smânia Jr A, Zani CL 2000. Biological screening of Brazilian medicinal plants. Mem Inst Oswaldo Cruz 95: 367-373. ''K. variabilis'' has been shown to contain three flavonols and a biflavone known to show Antioxidant, antioxidant activity: quercitrin, Isoquercetin, quercetin-3-O-β-glucoside, Hyperoside, quercetin-3-O-β-galactoside; and podocarpusflavone A (the biflavone). In 2019 a new acylphoroglucinol isolated from the branches of the tree showed activity against Methicillin-resistant Staphylococcus aureus, Methicillin-resistant ''Staphylococcus aureus'' (MRSA).

Carl Friedrich Philipp Von Martius
Carl Friedrich Philipp (Karl Friedrich Philipp) von Martius (17 April 1794 – 13 December 1868) was a German botanist and explorer. Life Martius was born at Erlangen, the son of Prof Ernst Wilhelm Martius, court apothecary. He graduated PhD from Erlangen University in 1814, publishing as his thesis a critical catalogue of plants in the university's botanical garden. After that he continued to devote himself to botanical study, and in 1817 he and Johann Baptist von Spix were sent to Brazil by Maximilian I Joseph, the king of Bavaria. They travelled from Rio de Janeiro through several of the southern and eastern provinces of Brazil and travelled up the Amazon River to Tabatinga, as well as exploring some of its larger tributaries. On his return to Europe in 1820 Martius was appointed as the keeper of the botanic garden at Munich, including the herbarium at the Munich Botanical Collection, and in 1826 as professor of botany in the university there, and he held both offices unti ...

Hyperoside
Hyperoside is a chemical compound. It is the 3-''O''-galactoside of quercetin. Natural occurrences Hyperoside has been isolated from ''Drosera rotundifolia'', from the Lamiaceae ''Stachys sp.'' and ''Prunella vulgaris'', from ''Rumex acetosella'', ''Cuscuta chinensis'' seeds, from St John's wort and from ''Camptotheca acuminata''. It is one of the phenolic compounds in the invasive plant ''Carpobrotus edulis'' and contributes to the antibacterial properties of the plant. In ''Rheum nobile'' and '' R. rhaponticum'', it serves as a UV blocker found in the bracts. It is also found in ''Geranium niveum'' and ''Taxillus kaempferi ''Taxillus kaempferi'' () is a parasitic plant A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant.

Medicinal Plants Of South America
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Cerrado
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Brazil
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methicillin-resistant Staphylococcus Aureus
Methicillin-resistant ''Staphylococcus aureus'' (MRSA) is a group of Gram-positive bacteria that are genetically distinct from other strains of ''Staphylococcus aureus''. MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths attributable to antimicrobial resistance in 2019. MRSA is any strain of ''S. aureus'' that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics. Beta-lactam (β-lactam) antibiotics are a broad-spectrum group that include some penams (penicillin derivatives such as methicillin and oxacillin) and cephems such as the cephalosporins. Strains unable to resist these antibiotics are classified as methicillin-susceptible ''S. aureus'', or MSSA. MRSA is common in hospitals, prisons, and nursing homes, where people with open wounds, invasive devices such as catheters, and weakened immune systems are at greater risk of healt ...

Isoquercetin
Isoquercetin, isoquercitrin or isotrifoliin is a flavonoid, a type of chemical compound. It is the 3-''O''-glucoside of quercetin. Isoquercitrin can be isolated from various plant species including ''Mangifera indica'' ( mango) and ''Rheum nobile'' (the Noble rhubarb). It is also present in the leaves of ''Annona squamosa'', '' Camellia sinensis'' (tea). and ''Vestia foetida'' Spectral data The lambda-max for isoquercetin is 254.8 and 352.6 nm. Potential clinical uses Isoquercetin is presently being investigated for prevention of thromboembolism in selected cancer patients and as an anti- fatigue agent in kidney cancer patients treated with sunitinib. There is a single case report of its use in the successful treatment of prurigo nodularis, a difficult to treat pruritic eruption of the skin. However it belongs to the PAINS (Pan-assay interference compounds) categories of chemicals. References See also * Quercitrin Quercitrin is a glycoside formed from the flavono ...
