Kaempferol
Kaempferol (3,4′,5,7-tetrahydroxyflavone) is a natural flavonol, a type of flavonoid, found in a variety of plants and plant-derived foods including kale, beans, tea, spinach, and broccoli. Kaempferol is a yellow crystalline solid with a melting point of . It is slightly soluble in water and highly soluble in hot ethanol, ethers, and DMSO. Kaempferol is named for 17th-century German naturalist Engelbert Kaempfer.Kaempferol at Merriam-Webster.com; retrieved October 20, 2017 Natural occurrence Kaempferol is a secondary metabolite found in many plants, plant-derived foods, and traditional medicines.

Endive
Endive () is a leaf vegetable belonging to the genus ''Cichorium'', which includes several similar bitter-leafed vegetables. Species include '' Cichorium endivia'' (also called endive), ''Cichorium pumilum'' (also called wild endive), and ''Cichorium intybus'' (also called common chicory). Common chicory includes types such as radicchio, puntarelle, and Belgian endive. There is considerable confusion between ''Cichorium endivia'' and ''Cichorium intybus''. ''Cichorium endivia'' There are two main varieties of cultivated ''C. endivia'' chicon: * Curly endive, or frisée (var ''crispum''). This type has narrow, green, curly outer leaves. It is sometimes called chicory in the United States and is called ''chicorée frisée'' in French. Further confusion results from the fact that frisée also refers to greens lightly wilted with oil. * Escarole, or broad-leaved endive (var ''latifolia''), has broad, pale green leaves and is less bitter than the other varieties.

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins ( flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non ...

Capers
''Capparis spinosa'', the caper bush, also called Flinders rose, is a perennial plant that bears rounded, fleshy leaves and large white to pinkish-white flowers. The plant is best known for the edible flower buds (capers), used as a seasoning or garnish, and the fruit (caper berries), both of which are usually consumed salted or, alternatively, pickled. Other species of ''Capparis'' are also picked along with ''C. spinosa'' for their buds or fruits. Other parts of ''Capparis'' plants are used in the manufacture of medicines and cosmetics. ''Capparis spinosa'' is native to almost all the circum-Mediterranean countries, and is included in the flora of most of them, but whether it is indigenous to this region is uncertain. The family Capparaceae could have originated in the tropics, and later spread to the Mediterranean basin. The taxonomic status of the species is controversial and unsettled. Species within the genus ''Capparis'' are highly variable, and interspecific hybrids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilex
''Ilex'' (), or holly, is a genus of over 570 species of flowering plants in the family (biology), family Aquifoliaceae, and the only living genus in that family.

Hypericum Perforatum
''Hypericum perforatum'', known as St. John's wort, is a flowering plant in the family Hypericaceae and the type species of the genus ''Hypericum''. Possibly a hybrid between '' H. maculatum'' and '' H. attenuatum'', the species can be found across temperate areas of Eurasia and has been introduced as an invasive weed to much of North and South America, as well as South Africa and Australia. While the species is harmful to livestock and can interfere with prescription drugs, it has been used in folk medicine over centuries, and remains commercially cultivated in the 21st century. Hyperforin, a phytochemical constituent of the species, is under basic research for possible therapeutic properties. Description ''Hypericum perforatum'' is an herbaceous perennial plant with extensive, creeping rhizomes. Its reddish stems are erect and branched in the upper section, and can grow up to high. The stems are woody near their base and may appear jointed from leaf scars. The branche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavonol
Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone (IUPAC name : 3-hydroxy-2-phenylchromen-4-one). Their diversity stems from the different positions of the phenolic -OH groups. They are distinct from flavanols (with "a") such as catechin, another class of flavonoids. Flavonols are present in a wide variety of fruits and vegetables. In Western populations, estimated daily intake is in the range of 20–50 mg per day for flavonols. Individual intake varies depending on the type of diet consumed. The phenomenon of dual fluorescence (due to excited state intramolecular proton transfer or ESIPT) is induced by tautomerism of flavonols (and glucosides) and could contribute to plant UV protection and flower colour. Besides being a subclass of flavonoids, flavonols are suggested by a study of cranberry juice to play a role along with proanthocyanidins, in the juice's ability to block bacterial adhesion, demonstrated by the compressing the fimbria of ' ...

Saffron
Saffron () is a spice derived from the flower of ''Crocus sativus'', commonly known as the "saffron crocus". The vivid crimson stigma and styles, called threads, are collected and dried for use mainly as a seasoning and colouring agent in food. Although some doubts remain on its origin, it is believed that saffron originated in Iran. However, Greece and Mesopotamia have also been suggested as the possible region of origin of this plant. Saffron crocus slowly propagated throughout much of Eurasia and was later brought to parts of North Africa, North America, and Oceania. Saffron's taste and iodoform-like or hay-like fragrance result from the phytochemicals picrocrocin and safranal. It also contains a carotenoid pigment, crocin, which imparts a rich golden-yellow hue to dishes and textiles. Its recorded history is attested in a 7th-century BC Assyrian botanical treatise, and has been traded and used for thousands of years. In the 21st century, Iran produces some 90% of ...

Sambucus Nigra
''Sambucus nigra'' is a species complex of flowering plants in the family Adoxaceae native to most of Europe. Common names include elder, elderberry, black elder, European elder, European elderberry, European black elderberry and tramman (Isle of Man).

Rosmarinus Officinalis
''Salvia rosmarinus'' (), commonly known as rosemary, is a shrub with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region. Until 2017, it was known by the scientific name ''Rosmarinus officinalis'' (), now a synonym. It is a member of the sage family Lamiaceae, which includes many other medicinal and culinary herbs.
