Charles Louis L'Héritier De Brutelle
Charles Louis L'Héritier de Brutelle (; 15 June 1746 – 18 August 1800) was an 18th-century France, French botanist and civil servant. Born into an affluent upper-class Parisian family, connections with the French Royal Court secured him the position of Superintendent of Parisian Waters and Forests at the age of twenty-six. In this capacity, L'Héritier conducted various studies of native trees and shrubs, also gaining interest in Introduced species, exotic flora. The abbreviation L'Herit. is also used. Early life Apart from what is stated above, little is known of his early life before his first employment. He appears to have been self-taught in botany, after taking up the superintendency. In 1775 L'Héritier was appointed a magistrate in the ''Cour des Aides'' in Paris. This was a court which dealt with tax offences, but under its president Guillaume-Chrétien de Lamoignon de Malesherbes, Malesherbes it became perhaps the only French government institution to protect ordinary ...

Apigenin
Apigenin (4′,5,7-trihydroxyflavone), found in many plants, is a natural product belonging to the flavone class that is the aglycone of several naturally occurring glycosides. It is a yellow crystalline solid that has been used to dye wool. Sources in nature Apigenin is found in many fruits and vegetables, but parsley, celery, celeriac, and chamomile tea are the most common sources. Apigenin is particularly abundant in the flowers of chamomile plants, constituting 68% of total flavonoids. Dried parsley can contain about 45 mg apigenin/gram of the herb, and dried chamomile flower about 3-5 mg/gram. The apigenin content of fresh parsley is reportedly 215.5 mg/100 grams, which is much higher than the next highest food source, green celery hearts providing 19.1 mg/100 grams. Biosynthesis Apigenin is biosynthetically derived from the general phenylpropanoid pathway and the flavone synthesis pathway. The phenylpropanoid pathway starts from the aro ...

Sambubioside
Sambubiose is a disaccharide. It is the β-D-xylosyl-(1→2)-β-D-glucose. Sambubiose is a component of some glycoside pigments. The fruits of ''Viburnum dentatum'' appear blue. One of the major pigments is cyanidin 3-sambubioside, but the total mixture is very complex. Sambubiosides with anthocyanidins can also be found in ''Matthiola incana ''Matthiola incana'' is a species of flowering plant in the cabbage family Brassicaceae.

Luteolin-7-O-β-D-glucoside
Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O- glucoside of luteolin. Natural occurrences It can be found in ''Ferula varia'' and '' F. foetida'' in ''Campanula persicifolia'' and '' C. rotundifolia'', in the bamboo ''Phyllostachys nigra'', and in ''Teucrium gnaphalodes''. ; In food It can be found in dandelion (the highest concentration in the flowers, but also in the roots) and in ''Cynara scolymus'' (artichoke). Metabolism Flavone 7-O-beta-glucosyltransferase adds a glucose to luteolin. A cynaroside 7-O-glucosidase Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound.

Naringenin
Naringenin is a flavorless, colorless flavanone, a type of flavonoid. It is the predominant flavanone in grapefruit, and is found in a variety of fruits and herbs. Structure Naringenin has the skeleton structure of a flavanone with three hydroxy groups at the 4', 5, and 7 carbons. It may be found both in the aglycol form, naringenin, or in its glycosidic form, naringin, which has the addition of the disaccharide neohesperidose attached via a glycosidic linkage at carbon 7. Like the majority of flavanones, naringenin has a single chiral center at carbon 2, although the optical purity is variable. Racemization of S(-)-naringenin has been shown to occur fairly quickly. Sources and bioavailability Naringenin and its glycoside has been found in a variety of herbs and fruits, including grapefruit, bergamot, sour orange, tart cherries, tomatoes, cocoa, Greek oregano, water mint, as well as in beans. Ratios of naringenin to naringin vary among sources, as do enantiomeric ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luteolin
Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance. Luteolin is the principal yellow dye compound that is obtained from the plant ''Reseda luteola'', which has been used as a source of the dye since at least the first millennium B.C. Luteolin was first isolated in pure form, and named, in 1829 by the French chemist Michel Eugène Chevreul. The luteolin empirical formula was determined by the Austrian chemists Heinrich Hlasiwetz and Leopold Pfaundler in 1864. In 1896, the English chemist Arthur George Perkin proposed the correct structure for luteolin. Perkin's proposed structure for luteolin was confirmed in 1900 when the Polish-Swiss chemist Stanislaw Kostanecki (1860–1910) and his students A. Różycki and J. Tambor synthesized luteolin. Natural occurrences Luteolin is most often found in leaves, but it is also seen in rinds, barks, clover blossom, and ragweed pollen. It has also been isolated from the aromatic flowering plant, ''Salvia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teucrium
''Teucrium'' is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals. Description Plants in the genus ''Teucrium'' are perennial herbs or shrubs with four-cornered stems, often with simple hairs and sessile glands. The leaves are arranged in opposite pairs, simple or with three leaflets sometimes with lobed or serrated edges. The flowers are arranged in a thyrse, sometimes in a cyme in leaf axils. The flowers have five more or less similar sepals fused at the base, and the corolla is white or cream-coloured with five lobes forming two lips. The upper lip is usually much reduced in size and the lower lip has three lobes, the central lobe usually larger than the side lobes. There are four stamens att ...
