Calotropis
''Calotropis'' is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1810. It is native to southern Asia and North Africa. They are commonly known as milkweeds because of the latex they produce. ''Calotropis'' species are considered common weeds in some parts of the world. The flowers are fragrant and are often used in making floral tassels in some mainland Southeast Asian cultures. Fibers of these plants are called madar or mader. ''Calotropis'' species are usually found in abandoned farmland. Botanical description ''Calotropis gigantea'' and ''C. procera'' are the two most common species in the genus. Both plants can attain an average height of although they can occasionally become as tall as . The leaves are sessile and sub-sessile, opposite, ovate, cordate at the base. The flowers are about in size, with umbellate lateral cymes and are colored white to pink and are fragrant in case of ''C. procera'' while the flowers of ''C. gigantea'' ...

Calotropis Gigantea
''Calotropis gigantea'', the crown flower, is a species of '' Calotropis'' native to Cambodia, Vietnam, Bangladesh, Indonesia, Malaysia, Philippines,Thailand, Sri Lanka, India, China, Pakistan, and Nepal. It is a large shrub growing to tall. It has clusters of waxy flowers that are either white or lavender in colour. Each flower consists of five pointed petals and a small "crown" rising from the center which holds the stamens. The aestivation found in calotropis is valvate i.e. sepals or petals in a whorl just touch one another at the margin, without overlapping. The plant has oval, light green leaves and milky stem. The latex of ''Calotropis gigantea'' contains cardiac glycosides, fatty acids, and calcium oxalate. The roots also contain Calotropone. Pollination This plant plays host to a variety of insects and butterflies. It is the host plant for Hawaii's non-migratory monarch butterflies. ''Calotropis'' is an example of entomophily pollination (pollination by ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calotropis Procera
''Calotropis procera'' is a species of flowering plant in the family Apocynaceae that is native to North Africa, Northern and Afrotropical realm, Tropical Africa, West Asia, Western Asia, South Asia and Mainland Southeast Asia, Indochina (mainland Southeast Asia). It typically reaches a height between to , and rarely to as high as , and grows in sunny to partly-shaded habitats such as disturbed and overgrazed lands, rangeland, roadsides, river flats and coastal dunes. Its green fruits contain a toxic milky sap that is extremely bitter and turns into a latex-like substance, which is resistant to soap. Common names for the plant include apple of Sodom, Sodom apple, roostertree, king's crown, small crownflower, giant milkweed, rubber bush, and rubber tree. The names "Apple of Sodom" and "Dead Sea Apple" stem from the ancient authors Josephus and Tacitus, who described the plant growing in the area of biblical Sodom and Gomorrah, Sodom. Although not native to the New World, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calotropin
Calotropin is a toxic cardenolide found in plants in the family ''Asclepiadoideae''. In extreme cases, calotropin poisoning can cause respiratory and cardiac failure. Accidental poisoning is common in livestock who have ingested milkweed. Calotropin is commonly stored as a defense mechanism by insects that eat milkweeds as their main food source. Chemistry Calotropin is a toxic compound and is classified as a cardenolide-type cardiac glycoside. These molecules are related to steroids, and have a similar carbon backbone. Calotropin, like calactin, calotoxin, and uscharin, is based on calotropagenin, the precursor to these molecules. They have similar activity and are often found together in plants of the genus ''Calotropis''. Biosynthesis It is thought that the biosynthesis of calotropin is similar to that of digitoxin, another cardenolide. Digitoxin is more established as a medicine for cardiac insufficiency, and therefore the biosynthesis has been further studied. However, ...

Apocynaceae Genera
Apocynaceae (, from '' Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Notable members of the family include oleander, dogbanes, milkweeds, and periwinkles. The family is native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members as well. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry ( xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter ofte ...

Asclepiadoideae
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, it was treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family. They form a group of perennial herbs, twining shrubs, lianas or rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the type genus '' Asclepias'' (milkweeds). There are 348 genera, with about 2,900 species. They are mainly located in the tropics to subtropics, especially in Africa and South America. The florally-advanced tribe Stapelieae within this family contains several relatively familiar stem succulent genera, such as '' Orbea'', '' Huernia, Stapelia'' and '' Hoodia''. They are remarkable for the complex mechanisms which they have developed for pollination, independently parallel to the unrelated Orchidaceae, such as the grouping of their pollen into pollinia. The "fragrance" (or odor) of the flowers, often called "c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganesha
Ganesha or Ganesh (, , ), also known as Ganapati, Vinayaka and Pillaiyar, is one of the best-known and most worshipped Deva (Hinduism), deities in the Hindu deities, Hindu pantheon and is the Supreme God in the Ganapatya sect. His depictions are found throughout India. Hindu denominations worship him regardless of affiliations. Devotion to Ganesha is widely diffused and extends Ganesha in world religions, to Jains and Buddhists and beyond India. Although Ganesha has many attributes, he is readily identified by his Asiatic Elephant, elephant head and four arms. He is widely revered, more specifically, as the remover of obstacles and bringer of good luck; the patron of The arts, arts and Science, sciences; and the Deva (Hinduism), deva of intellect and wisdom. As the god of beginnings, he is honoured at the start of rites and ceremonies. Ganesha is also invoked during writing sessions as a patron of letters and learning., Vigna means obstacles Nasha means destroy. These ideas ar ...

Cardiac Glycoside
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias; however, their relative toxicity prevents them from being widely used. Most commonly found as defensive poisons in several plant genera such as ''Digitalis'' (the foxgloves) and '' Asclepias'' (the milkweeds), these compounds nevertheless have a diverse range of biochemical effects regarding cardiac cell function and have also been suggested for use in cancer treatment. Classification General structure The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar (glycoside) and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence th ...

Cytotoxic
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are toxic metals, toxic chemicals, microbe neurotoxins, radiation particles and even specific neurotransmitters when the system is out of balance. Also some types of drugs, e.g alcohol, and some venom, e.g. from the puff adder (''Bitis arietans'') or brown recluse spider (''Loxosceles reclusa'') are toxic to cells. Cell physiology Treating cells with the cytotoxic compound can result in a variety of prognoses. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis). Cells undergoing necrosis typically exhibit rapid swelling, lose membrane integrity, shut down metabolism, and release their contents into the environment. Cells that undergo rapid necrosis in vitro do not have sufficient t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
