Cordia Obliqua
''Cordia obliqua'', the clammy cherry, is a flowering plant species in the genus ''Cordia''. The larvae of '' Brenthia coronigera'', a species of moth found in Bengal, India, feeds on ''Cordia obliqua''. Hesperetin 7-rhamnoside, a glycoside of hesperetin Hesperetin is the 4'-methoxy derivative of eriodictyol, a flavanone.

Hesperetin
Hesperetin is the 4'-methoxy derivative of eriodictyol, a flavanone. Hesperetin's 7-O-glycoside, hesperidin, is a naturally occurring flavanon-glycoside, the main flavonoid in lemons and sweet oranges. Hesperetin (and naringenin, the parent flavanone of naringin) are not found to a significant extent in ''Citrus'' spp. Glycosides A variety of glycosides of hesperetin are known, including: * Hesperidin (hesperetin-7-''O''-rutinoside) is a water-insoluble flavonoid glycoside whose solubility is below 5 μg/ml in water. Hesperidin is found in citrus fruits and upon ingestion it releases its aglycone, hesperetin. * Neohesperidin is the 7-''O''-neohesperidoside of hesperetin. * Hesperetin-7-''O''-α-L-Rhamnopyranoside (CAS 66513-83-5) is found in the roots of clammy cherry (''Cordia obliqua'' a.k.a. ''Cordia obliqua'' var. ''wallichii''). Metabolism Hesperidin 6-''O''-α-L-rhamnosyl-β-D-glucosidase is an enzyme that uses hesperidin and H2O to produce hesperetin and rutinose. It ...

Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordia
''Cordia'' is a genus of flowering plants in the borage family, Boraginaceae. It contains about 300 species of shrubs and trees, that are found worldwide, mostly in warmer regions. Many of the species are commonly called manjack, while ''bocote'' may refer to several Central American species in Spanish. The generic name honours German botanist and pharmacist Valerius Cordus (1515–1544). Like most other Boraginaceae, the majority have trichomes (hairs) on the leaves. Taxonomy The taxonomy of ''Cordia'' is complex and controversial. Gottschling et al. (2005) say this is partly due to "extraordinarily high intraspecific variability" in some groups of species, making identification difficult, and partly due to new taxa having been "airily described on the basis of poorly preserved herbarium specimens". Selected species *''Cordia africana'' Lam. – White manjack *''Cordia alliodora'' ( Ruiz & Pav.) Oken – Spanish elm, Ecuador laurel, salmwood, bocote (Neotropics) *''Cordia bo ...

Brenthia Coronigera
''Brenthia coronigera'', commonly known as the metalmark moth, is a species of moth of the family Choreutidae. It was described by Edward Meyrick in 1918. It is found in the Bengal region of what was British India. The adult moth is a mimic of predatory jumping spiders; the moth's forewings are held aloft and have bold black spots, which resemble spider eyes, while its hindwings, which are held in a twisted position and are marked with stripes, resemble spider legs. The moth also moves in a jumpy, jerky fashion, like a jumping spider, rather than fluttering like other moths. Its mimicry is so convincing that spiders respond by trying to court the moth, rather than attacking it. The larvae feed on ''Cordia obliqua'' and ''Cordia myxa ''Cordia myxa'', the Assyrian plum, is a mid-sized, deciduous tree in the borage family (Boraginaceae), native to Asia. It produces small, edible fruit and is found in warmer areas across Africa and Asia. Other common names include lasura, lav .. ...

Bengal
Bengal ( ; bn, বাংলা/বঙ্গ, translit=Bānglā/Bôngô, ) is a geopolitical, cultural and historical region in South Asia, specifically in the eastern part of the Indian subcontinent at the apex of the Bay of Bengal, predominantly covering present-day Bangladesh and the Indian state of West Bengal. Geographically, it consists of the Ganges-Brahmaputra delta system, the largest river delta in the world and a section of the Himalayas up to Nepal and Bhutan. Dense woodlands, including hilly rainforests, cover Bengal's northern and eastern areas, while an elevated forested plateau covers its central area; the highest point is at Sandakphu. In the littoral southwest are the Sundarbans, the world's largest mangrove forest. The region has a monsoon climate, which the Bengali calendar divides into six seasons. Bengal, then known as Gangaridai, was a leading power in ancient South Asia, with extensive trade networks forming connections to as far away as Roman Egypt. ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...
