Fagara Macrophylla
''Zanthoxylum gilletii'', the East African satinwood, is a tree species in the genus ''Zanthoxylum'' found in Africa. The fruits are used to produce the spice uzazi. Chemistry The alkaloid nitidine can be isolated from the plant. The amide alkaloids N-(4-hydroxyphenethyl)octacosanamide, N-(4-hydroxyphenethyl)hexacosanamide, N-(4-hydroxyphenethyl)decanamide, N-vanilloyltyramine and N- -docosanoylvanilloylyramine can be isolated from the stem bark. The lignan sesamin, the N-isobutylamide γ-sanshool, the acridone alkaloids 1-hydroxy-3-methoxy-N-methylacridone, arborinine, xanthoxoline and 1-hydroxy-3-methoxyacridone can also be extracted from the bark as well as the alkaloids oblongine, tembetarine and magnoflorine and the flavonoid hesperidin Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees. Hesperidin was first isolated in 1828 by F ...

Émile Auguste Joseph De Wildeman
Émile Auguste Joseph De Wildeman (19 October 1866, Saint-Josse-ten-Noode – 1947) was a Belgian botanist and phycologist. He is known for his investigations of Congolese flora. From 1883 to 1887, he studied pharmacy at the Université libre de Bruxelles. In 1891, he began work as a preparateur at the Jardin Botanique National de Belgique, an institution where he later served as director. In 1892, he received his doctorate in sciences (academic advisor, Leo Errera) and in 1926 attained the title of professor.

Flora Of Africa
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] |
Hesperidin
Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees. Hesperidin was first isolated in 1828 by French chemist M. Lebreton from the white inner layer of citrus peels (mesocarp, albedo). Hesperidin is believed to play a role in plant defense. Sources ''Rutaceae'' * 700–2,500 ppm in fruit of ''Citrus aurantium'' (bitter orange, petitgrain) * in orange juice (''Citrus sinensis'') * in ''Zanthoxylum gilletii'' * in lemon * in lime * in leaves of ''Agathosma serratifolia'' ''Lamiaceae'' Peppermint contains hesperidin.

Magnoflorine
''(S)-''Magnoflorine is a quaternary benzylisoquinoline alkaloid (BIA) of the aporphine structural subgroup which has been isolated from various species of the family Menispermaceae, such as ''Pachygone ovata,'' '' Sinomenium acutum,'' and ''Cissampelos pareira.'' It was identified among the verified anti-inflammatory components in an extract of ''Sinomenii caulis'' and has been proposed to have other potential physiological effects, such as sedative and anxiolytic, reduction of erythrocyte hemolysis, antifungal activity, improvement of LPS-induced acute lung injury, and protection against muscle atrophy. Furthermore, magnoflorine has been identified to be an inhibitor of NF-κB activation and to be an agonist An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the ago ... at the β2 -adren ...

Acridone Alkaloids
Acridone alkaloids are natural products derived from acridone. Occurrence Acridone alkaloids are found in bark, wood, leaves and roots of rue plants, especially in roots and suspension cultures of rue. Examples This group is named after the acridone. Further members are acronycin, melicopicine and rutacridone, among others:{{cite web, title=Acridone alkaloid biosynthesis, periodical=, publisher=, url=https://www.genome.jp/kegg/pathway/map/map01058.html, url-status=, format=, access-date=22 April 2020, archive-url=, archive-date=, last=, date=, year=, language=en, pages=, quote= Acronycine Structural Formula V1.svg, Acronycin Melicopicine Structural Formula V1.svg, Melicopicine Rutacridone Structural Formula V1.svg, Rutacridon Properties Many acridone alkaloids are methylated on the nitrogen atom and also have two oxygen functional groups, which can be free, alkylated or incorporated into rings.

Zanthoxylum
''Zanthoxylum'' is a genus of about 250 species of deciduous and evergreen trees, shrubs and climbers in the family Rutaceae that are native to warm temperate and subtropical areas worldwide. It is the type genus of the tribe Zanthoxyleae in the subfamily Rutoideae. Several of the species have yellow heartwood, to which their generic name alludes. Description Plants in the genus ''Zanthoxylum'' are typically dioecious shrubs, trees or woody climbers armed with trichomes. The leaves are arranged alternately and are usually pinnate or trifoliate. The flowers are usually arranged in panicles and usually function as male or female flowers with four sepals and four petals, the sepals remaining attached to the fruit. Male flowers have four stamens opposite the sepals. Female flowers have up to five, more or less free carpels with the styles free or sometimes fused near the tip. The fruit is usually of up to four follicles fused at the base, each containing a single seed almost a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
