Glossary Phytochemicals A!

Online Glossary edited with meticulous attitude and published as convenience for site content reference,including glossaries of related different topics,Glossary Phytochemicals are dedicated to Phytochemicals and phyto derived chemical components.Phytochemicals have been used as drugs for millennia. Hippocrates may have prescribed willow tree leaves to abate fever. Salicin, having anti-inflammatory and pain-relieving properties, was originally extracted from the white willow tree and later synthetically produced become the staple over-the-counter drug called Aspirin!

Glossary Phytochemicals Icon01
Phytochemicals are chemical compounds such as beta-carotene that occur naturally in plants. The term is generally used to refer to those chemicals that may affect health, but are not yet established as essential nutrients.While there is abundant scientific and government support for recommending diets rich in fruits and vegetables, there is only limited evidence that health benefits are due to specific phytochemicals.

Glossary Phytochemicals Icon02
There is evidence from laboratory studies that phytochemicals in fruits and vegetables may reduce the risk of cancer, possibly due to dietary fibers, polyphenol antioxidants and anti-inflammatory effects. Specific phytochemicals, such as fermentable dietary fibers, are allowed limited health claims by the US Food and Drug Administration (FDA).

Alkaloid:a plant-derived compound that is biologically active, contains a nitrogen in a heterocyclic ring, is alkaline, has a complex structure, and is of limited distribution in the plant kingdom.
alkaloids:organic, nitrogenous-containing bases, usually with a heterocyclic ring of some kind; divided into three main categories: 1) true alkaloids - nitrogen-containing heterocyclic compounds derived from an amino acid, e.g. benzylisoquinoline alkaloids, tropane alkaloids, quinolizidine alkaloids, 2) protoalkaloids - derived from amino acids, but lacking a heterocyclic ring, 3) pseudoalkaloids - derived from terpenes, sterols, aliphatic acids, nicotinic acid, or purines. Note that similar alkaloids can have quite different biosynthetic pathways, indeed, alkaloids are rather like species - you know what they are, but cannot define them...

alkannin:a naphthoquinone derived from the p-hydroxybenzoic acid pathway (S = shikonin isomer), the coloring ingredient of alkanet; alkannin paper is an indicator of acidity, alkalis turning the paper blue, acids red (see the color changes as flowers of some Boraginaceae-Boraginoideae age).
