Moraceae
Moraceae is a family of flowering plants comprising about 48 genera and over 1100 species, and is commonly known as the mulberry or fig family. Most are widespread in tropical and subtropical regions, less so in temperate climates; however, their distribution is cosmopolitan overall. The only common characteristics within the family are the presence of latex-producing glands in the leaves and stems, and milky sap in the soft tissues; but generally useful field characters include two carpels sometimes with one reduced, compound inconspicuous flowers, and compound fruits. The family includes well-known plants such as the common fig, breadfruit, jackfruit and mulberry. The 'flowers' of Moraceae are often pseudanthia (reduced inflorescences). Description Overall The family varies from colossal trees like the Indian Banyan ('' Ficus benghalensis'') which can cover of ground, to '' Dorstenia barnimiana'' which is a small stemless, bulbous succulent 2–5 cm in diameter that pr ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Rigidoporus Microporus
''Rigidoporus microporus'' is a plant pathogen, known to cause white root rot disease on various tropical crops, such as cacao, cassava, tea, with economical importance on the para rubber tree (''Hevea brasiliensis''). White root rot of rubber ''Rigidoporus lignosus'' (klotzsch) Imazeki, the causal agent of white root rot, was first reported on rubber in 1904 from Botanical Gardens, Singapore. It belongs to the order Basidiomycete, and in the family Polyporaceae. The disease originates on roots and later spreads to collar region. Foliar symptoms are initiated subsequently with the destruction of the root system. Its above ground symptoms indicates that the trees are mostly beyond treatment and recovery, as rapid progress of infection makes death imminent. This disease caused significant mortality to tree irrespective of age or health status, causing economic losses to the latex industry in many countries. It is the most destructive root disease in rubber plantations in Sri Lanka a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hevea Brasiliensis
''Hevea brasiliensis'', the Pará rubber tree, ''sharinga'' tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family, Euphorbiaceae, originally native to the Amazon basin, but is now pantropical in distribution due to introductions. It is the most economically important member of the genus ''Hevea'' because the milky latex extracted from the tree is the primary source of natural rubber. Description ''Hevea brasiliensis'' is a tall deciduous tree growing to a height of up to in the wild. Cultivated trees are usually much smaller because drawing off the latex restricts their growth. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged. The leaves have three leaflets and are spirally arranged. The inflorescences include separate male and female flowers. The flowers are pungent, creamy-yellow and have no petals. The fruit is a c ...

Ascaris Lumbricoides
''Ascaris lumbricoides'' is a large parasitic worm, parasitic Nematoda, roundworm of the genus ''Ascaris.'' It is the most common parasitic worm in humans. An estimated 807 million–1.2 billion people are infected with ''Ascaris lumbricoides'' worldwide. People living in tropics, tropical and subtropics, subtropical countries are at greater risk of infection. Infection by ''Ascaris lumbricoides'' is known as ascariasis. It has been proposed that ''Ascaris lumbricoides'' and ''Ascaris suum'' (pig roundworm) are the same species. Life cycle ''Ascaris lumbricoides'', a roundworm, infects humans via the fecal-oral route. Eggs released by adult females are shed in feces. Unfertilized eggs are often observed in fecal samples but never become infective. Fertilized eggs embryonate and become infectious after 18 days to several weeks in soil, depending on the environmental conditions (optimum: moist, warm, shaded soil).Parasites - Ascariasis.

Prenylated Flavonoid
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid. Monoprenyl isoflavone epoxidase is a key enzyme in fungal ''Botrytis cinerea'' metabolism of prenylated flavonoids. Many prenylflavonoids appear to have anticancer activity in vitro. Prenylchalcones, prenylflavones, prenylflavonols and prenylflavanones are classes of prenylflavonoids. Examples 6-Prenylnaringenin, 6-geranylnaringenin, 8-prenylnaringenin and isoxanthohumol can be found in hops and beer. Of the prenylflavonoids, 8-prenylnaringenin is the most potent phytoes ...

Xanthonoid
A xanthonoid is a chemical natural phenolic compound formed from the xanthone backbone. Many members of the Clusiaceae The Clusiaceae or Guttiferae Juss. (1789) (''nom. alt. et cons.'' = alternative and valid name) are a family (biology), family of plants including 13 genera and ca 750 species. Several former members of Clusiacae are now placed in Calophyllaceae ... contain xanthonoids. Xanthonoid biosynthesis in cell cultures of '' Hypericum androsaemum'' involves the presence of a benzophenone synthase condensing a molecule of benzoyl-CoA with three malonyl-CoA yielding to 2,4,6-trihydroxybenzophenone. This intermediate is subsequently converted by a benzophenone 3′-hydroxylase, a cytochrome P450 monooxygenase, leading to the formation of 2,3′,4,6-tetrahydroxybenzophenone. Some examples are tomentonone, zeyloxanthonone and calozeyloxanthone isolated from the bark of '' Calophyllum tomentosum'', apetalinone A, B, C and D from '' Calophyllum apetalum'', gaud ...

Geranyl
Geraniol is a monoterpenoid and an alcohol. It is the primary component of citronella oil and is a primary component of rose oil and palmarosa oil. It is a colorless oil, although commercial samples can appear yellow. It has low solubility in water, but it is soluble in common organic solvents. Uses and occurrence In addition to being found in rose oil, palmarosa oil, and citronella oil, it also occurs in small quantities in geranium, lemon, and many other essential oils. With a rose-like scent, it is commonly used in perfumes and in scents such as peach, raspberry, grapefruit, red apple, plum, lime, orange, lemon, watermelon, pineapple, and blueberry. Geraniol is produced by the scent glands of honeybees to mark nectar-bearing flowers and locate the entrances to their hives. It is also commonly used as an insect repellent, especially for mosquitoes. The scent of geraniol is reminiscent of, but chemically unrelated to, 2-ethoxy-3,5-hexadiene, also known as geranium taint ...

Chalconoid
Chalconoids ( Greek: χαλκός ''khalkós'', "copper", due to its color), also known as chalcones, are natural phenols In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (− O H) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, . Phenolic compounds ar ... derived from chalcone. They form the central core for a variety of important biological compounds. They show antibacterial, antifungal, antitumor and anti-inflammatory properties. Some chalconoids demonstrated the ability to block voltage-dependent potassium channels. Chalcones are also natural aromatase inhibitors. Chalcones are aromatic ketones with two phenyl rings that are also intermediates in the synthesis of many biological compounds. The closure of hydroxy chalcones causes the formation of the flavonoid structure. Flavonoids are substances in the plant's secondary metabolism with an array of bio ...
