Cymbopogon Citratus
''Cymbopogon citratus'', commonly known as West Indian lemon grass or simply lemon grass, is a tropical plant native to Maritime Southeast Asia and introduced to many tropical regions. ''Cymbopogon citratus'' is often sold in stem form. While it can be grown in warmer temperate regions, such as the UK, it is not hardy to frost. Morphology ''Cymbopogon citratus'' is part of the grass family, Poaceae. They contain simple, bluish-green leaves with entire margins and are linear in shape. The blades tend to be 18–36 inches long. Like other grasses, the leaves also have parallel venation. Distribution ''Cymbopogon citratus'' is native to Island Southeast Asia (Malesia). It has been introduced extensively to South Asia since precolonial times. After the World War I, lemongrass was introduced to Madagascar, South America, and Central America. It has now been naturalized throughout the tropics and subtropics worldwide. In its native range, ''Cymbopogon citratus'' is known as ''s ...

Augustin Pyrame De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Proto-Austronesian Language
Proto-Austronesian (commonly abbreviated as PAN or PAn) is a proto-language. It is the reconstructed ancestor of the Austronesian languages, one of the world's major language families. Proto-Austronesian is assumed to have begun to diversify 3,500–4,000 BCE on Taiwan. Lower-level reconstructions have also been made, and include Proto-Malayo-Polynesian, Proto-Oceanic, and Proto-Polynesian. Recently, linguists such as Malcolm Ross and Andrew Pawley have built large lexicons for Proto-Oceanic and Proto-Polynesian. Phonology Proto-Austronesian is reconstructed by constructing sets of correspondences among consonants in the various Austronesian languages, according to the comparative method. Although in theory the result should be unambiguous, in practice given the large number of languages there are numerous disagreements, with various scholars differing significantly on the number and nature of the phonemes in Proto-Austronesian. In the past, some disagreements concerned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citronellol
Citronellol, or dihydrogeraniol, is a natural acyclic monoterpenoid. Both enantiomers occur in nature. (+)-Citronellol, which is found in citronella oils, including ''Cymbopogon nardus'' (50%), is the more common isomer. (−)-Citronellol is widespread, but particularly abundant in the oils of rose (18–55%) and ''Pelargonium'' geraniums. Preparation Several million kilograms of citronellol are produced annually. It is mainly obtained by hydrogenation of geraniol or nerol over copper chromite catalyst. Homogeneous catalysts are used for the production of enantiomers. Citronellene is also a precursor. Uses Citronellol is used in perfumes and as a fragrance in cleaning products. In many applications, one of the enantiomers is preferred. It is a component of citronella oil, an insect repellant. Citronellol is used as a raw material for the production of rose oxide. It is also a precursor to many commercial and potential fragrances such as citronellol acetate, citronelly ...

Citronellal
Citronellal or rhodinal ( C10 H18 O) is a monoterpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent. Citronellal is a main isolate in distilled oils from the plants '' Cymbopogon'' (excepting C. citratus, culinary lemongrass), lemon-scented gum, and lemon-scented teatree. The (''S'')-(−)- enantiomer of citronellal makes up to 80% of the oil from kaffir lime leaves and is the compound responsible for its characteristic aroma. Citronellal has insect repellent properties, and research shows high repellent effectiveness against mosquitoes. Another research shows that citronellal has strong antifungal qualities.

Myrcene
Myrcene, or β-myrcene, is a monoterpene. A colorless oil, it occurs widely in essential oils. It is produced mainly semi-synthetically from '' Myrcia'', from which it gets its name. It is an intermediate in the production of several fragrances. α-Myrcene is the name for the isomer 2-methyl-6-methylene-1,7-octadiene, which has not been found in nature. Production Myrcene is often produced commercially by the pyrolysis (400 °C) of β-pinene, which is obtained from turpentine. It is rarely obtained directly from plants. Plants biosynthesize myrcene via geranyl pyrophosphate (GPP), which isomerizes into linalyl pyrophosphate. The release of the pyrophosphate (OPP) and a proton completes the conversion. Occurrence It could in principle be extracted from any number of plants, such as verbena or wild thyme, the leaves of which contain up to 40% by weight of myrcene. Many other plants contain myrcene, sometimes in substantial amounts. Some of these include cannabis, hops, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citral
Citral is an acyclic monoterpene aldehyde, and being a monoterpene, it is made of two isoprene units. Citral is a collective term which covers two geometric isomers that have their own separate names; the ''E''-isomer is named geranial (''trans''-citral) or citral A. The ''Z''-isomer is named neral (''cis''-citral) or citral B. These stereoisomers occur as a mixture, not necessarily racemic; e.g. in essential oil of Australian ginger, the neral to geranial ratio is 0.61. Occurrence Citral is present in the oils of several plants, including lemon myrtle (90–98%), '' Litsea citrata'' (90%), '' Litsea cubeba'' (70–85%), lemongrass (65–85%), lemon tea-tree (70–80%), ''Ocimum gratissimum'' (66.5%), '' Lindera citriodora'' (about 65%), '' Calypranthes parriculata'' (about 62%), petitgrain (36%), lemon verbena (30–35%), lemon ironbark (26%), lemon balm (11%), lime (6–9%), lemon (2–5%), and orange. Further, in the lipid fraction (essential oil) of Australian ginger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miang Kham
Miang kham ( th, เมี่ยงคำ, , ) is a traditional Southeast Asian snack from Thailand and Laos ( lo, ໝ້ຽງຄຳ ). It was introduced to the Siamese court of King Rama V by Princess Dara Rasmi. In Malaysia it is called Sirih Kaduk. The name ''miang kham'' translates to 'one bite wrap', from ''miang'' ('food wrapped in leaves') and ''kham'' ('a bite').

Tom Kha Kai
''Tom kha kai'', ''tom kha gai'', or Thai coconut soup ( th, ต้มข่าไก่, ; ) is a spicy and sour hot soup with coconut milk in Thai cuisine. Ingredients In Thailand, most ''tom kha kai'' recipes typically include coconut milk, galangal (sometimes substituted with ginger), kaffir lime leaves, lemongrass, Thai chili, coriander (or dill), straw mushrooms (or shiitake or other mushrooms), chicken, fish sauce, and lime juice. Fried chilies are sometimes added. Variations In a Thai-style ''tom kha kai'', dill weed is not used, whereas in a Lao-style ''tom kha kai'', dill weed (''phak si'', lo, ຜັກຊີ) is used. Dill weed is a common herb used in Lao cuisine. The Thais' answer to dill weed (known in Thailand as ''phak chi Lao'' ( th, ผักชีลาว), since it is known locally as a Lao herb) in Thai ''tom kha'' is coriander or cilantro (''phak chi'', th, ผักชี). There are other versions of ''tom kha kai'' made with seafood (''tom k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tom Yam
Tom yum or tom yam (, ; th, ต้มยำ, ) is a type of hot and sour Thai soup, usually cooked with shrimp (prawn). The words "tom yam" are derived from two Thai words. ''Tom'' refers to the boiling process, while ''yam'' means 'mixed'. Tom yum is characterised by its distinct hot and sour flavours, with fragrant spices and herbs generously used in the broth. The soup is also made with fresh ingredients such as lemongrass, kaffir lime leaves, galangal, lime juice, fish sauce, and crushed red chili peppers. The tom yum seasoning has been investigated as a potential functional food and a natural antimicrobial because of its kaffir lime leaf and red chili content. Commercial tom yum paste is made by crushing all the herb ingredients and stir frying in oil, then adding seasoning and other preservative ingredients.The paste is bottled or packaged and sold around the world. Tom yum flavored with the paste may have different characteristics from that made with fresh herb ingre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lechon
A suckling pig is a piglet fed on its mother's milk (i.e., a piglet which is still a " suckling"). In culinary contexts, a suckling pig is slaughtered between the ages of two and six weeks. It is traditionally cooked whole, often roasted, in various cuisines. It is usually prepared for special occasions and gatherings. The most popular preparation can be found in Spain and Portugal under the name ''lechón'' (Spanish) or ''leitão'' (Portuguese). The meat from suckling pig is pale and tender and the cooked skin is crisp and can be used for pork rinds. The texture of the meat can be somewhat gelatinous due to the amount of collagen in a young pig. History There are many ancient recipes for suckling pig from Roman and Chinese cuisine. Since the pig is one of the first animals domesticated by human beings for slaughter, many references to pigs are found in human culture. The suckling pig, specifically, appears in early texts such as the sixth-century Salic law. As an exam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
