Santin

Santin is an O-methylated flavonol. It can be found in Tanacetum microphyllum.

Properties
Sodium

Sodium is a soft, silvery-white, highly reactive metal and is a member of the alkali metals within group 1.It is an essential element for all animal life and for some plant species. In animals, sodium ions are used in opposition to potassium ions, to allow the organism to build up an electrostatic charge on cell membranes, and thus allow transmission of nerve impulses when the charge is allowed to dissipate by a moving wave of voltage change.

Tannin

Tannin is an astringent, bitter plant polyphenolic compound that binds to and precipitates proteins and various other organic compounds including amino acids and alkaloids.Tannins have molecular weights ranging from 500 to over 3,000.Tannins are incompatible with alkalis, gelatin, heavy metals, iron, lime water, metallic salts, strong oxidizing agents and zinc sulfate, since they form complexes and precipitate in aqueous solution.Tannins are distributed in species throughout the plant kingdom. They are commonly found in both gymnosperms as well as angiosperms.Tannins have traditionally been considered antinutritional but it is now known that their beneficial or antinutritional properties depend upon their chemical structure and dosage.Tannins are an important ingredient in the process of tanning leather. Oak bark, mimosa, chestnut and quebracho tree have traditionally been the primary source of tannery tannin, though inorganic tanning agents are also in use today and account for 90% of the world's leather production.Tannins can be used for production of anti-corrosive primer, sold under brand name-Nox Primer for treatment of rusted steel surfaces prior to painting, rust converter to transform oxidized steel into a smooth sealed surface and rust inhibitor.

Properties
Tetuin

Tetuin is a flavone, a type of flavonoid. It is the 6-O-glucoside of baicalein. It can be isolated from the seeds of Oroxylum indicum, the Indian trumpetflower.

Properties
Thiram

Thiram is used as a fungicide, ectoparasiticide to prevent fungal diseases in seed and crops.

Tricin

Tricin is a chemical compound. It is an O-methylated flavone, a type of flavonoid. It can be found in the rice bran.

Properties
Uracil

Uracil is a common and naturally occurring pyrimidine derivative.It is a planar, unsaturated compound that has the ability to absorb light.It was isolated by hydrolysis of yeast nuclein that was found in bovine thymus and spleen, herring sperm, and wheat germ.It is involved in the transmission of hereditary characteristics.Uracil is one of four nitrogenous bases found in the RNA molecule.It is the hydrogen bond acceptor and can form two hydrogen bonds.It can also bind with a ribose sugar to form the ribonucleoside uridine.It can be used for drug delivery and as a pharmaceutical,used to determine microbial contamination of tomatoes.Its derivatives are more often used as antiphotosynthetic herbicides, destroying weeds in cotton, sugar beet, turnips, soya, peas, sunflower crops, vineyards, berry plantations, and orchards.

Zircon

Zircon is a mineral belonging to the group of nesosilicates. Zircon forms in silicate melts with large proportions of high field strength incompatible elements. Zircon is ubiquitous in the crust of Earth. It occurs in igneous rocks (as primary crystallization products), in metamorphic rocks and in sedimentary rocks (as detrital grains). Zircon is a common accessory to trace mineral constituent of most granite and felsic igneous rocks. Zircon is mainly consumed as an opacifier in the decorative ceramics industry. It is also the principal precursor not only to metallic zirconium, although this application is small, but also to all compounds of zirconium including zirconium oxide (ZrO2), one of the most refractory materials known. It has played an important role during the evolution of radiometric dating. Zircons contain trace amounts of uranium and thorium (from 10 ppm up to 1 wt %) and can be dated using several modern analytical techniques.
