Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ...

Contact Dermatitis
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable. Contact dermatitis results from either exposure to allergens ( allergic contact dermatitis), or irritants ( irritant contact dermatitis). Allergic contact dermatitis involves a delayed type of hypersensitivity and previous exposure to an allergen to produce a reaction. Irritant contact dermatitis is the most common type and represents 80% of all cases. It is caused by prolonged exposure to irritants, leading to direct injury of the epidermal cells of the skin, which activates an immune response, resulting in an inflammatory cutaneous reaction. Phototoxic dermatitis occurs when the allergen or irritant is activated by sunlight. Diagnosis of allergic contact dermati ...

Soil PH
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as  ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH values ...

Urushiol
Urushiol is an oily mixture of organic compounds with Allergic contact dermatitis, allergenic properties found in plants of the Family (biology), family Anacardiaceae, especially ''Toxicodendron'' ''spp.'' (e.g., poison oak, Toxicodendron vernicifluum, Chinese lacquer tree, Toxicodendron radicans, poison ivy, Toxicodendron vernix, poison sumac), Comocladia, ''Comocladia spp.'' (maidenplums), Metopium, ''Metopium spp''. (poisonwood), and also in parts of the Mangifera indica, mango tree and the fruit of the cashew tree. In most individuals, urushiol causes an allergic skin rash on contact, known as urushiol-induced contact dermatitis. The name urushiol is derived from the Japanese language, Japanese word for the lacquer tree, . The oxidation and polymerization of urushiol in the tree's sap in the presence of moisture allows it to form a hard lacquer, which is used to produce traditional Chinese, Korean, and Japanese lacquerware.

Xanthone
Xanthone is an organic compound with the molecular formula C13H8O2. It is a white solid. In 1939, xanthone was introduced as an insecticide and it currently finds uses as ovicide for codling moth eggs and as a larvicide. Xanthone is also used in the preparation of xanthydrol, which is used in the determination of urea levels in the blood. It can also be used as a photocatalyst. Synthesis Xanthone can be prepared by the heating of phenyl salicylate: Six methods have been reported for synthesizing xanthone derivatives: *The Michael-Kostanecki method uses an equimolar mix of a polyphenol and an ''O''-hydroxybenzoic acid, which are heated with a dehydrating agent. *The Friedel-Crafts method has a benzophenone intermediate. *The Robinson-Nishikawa method is a variant of the Hoesch synthesis but with low yields. *The Asahina-Tanase method synthesizes some methoxylated xanthones, and xanthones with acid-sensitive substituents. *The Tanase method is used to synthesize po ...

Mangiferin
Mangiferin is a glucosylxanthone (xanthonoid). This molecule is a glucoside of norathyriol. Natural occurrences Mangiferin was first isolated from the leaves and bark of ''Mangifera indica'' (the mango tree). It can also be extracted from mango peels and kernels, ''Iris unguicularis'', ''Anemarrhena asphodeloides'' rhizomes and ''Bombax ceiba'' leaves. It is also found in the genera ''Salacia (plant), Salacia'' and ''Cyclopia (plant), Cyclopia'', as well as in coffee leaves and some species of ''Crocus''. Among the group of ''Asplenium hybrids'' known as the "Appalachian ''Asplenium'' complex", mangiferin and isomangiferin are produced only by ''Asplenium montanum'' and its hybrid descendants. The distinctive gold-orange fluorescence of these compounds under ultraviolet light has been used to aid in the chromatographic identification of hybrid ''Asplenium''s. Research Preliminary research is conducted on the potential biological properties of mangiferin, although there were ...

Drupe
In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. Drupes do not split open to release the seed, i.e., they are dehiscence (botany), indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with Superior ovary, superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, woody (lignified) stone is derived from the Ovary (botany), ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a Berry (botany), different definition of ''berry''. Other fleshy fruits may have a stony enclosur ...
