Homoisoflavanone
Homoisoflavonoids (3-benzylidenechroman-4-ones) are a type of phenolic compounds occurring naturally in plants. Chemically, they have the general structure of a 16-carbon skeleton, which consists of two phenyl rings (A and B) and heterocyclic ring (C). Synthesis Homoisoflavones can be synthesized from 2'-hydroxy dihydrochalcones. Homoisoflavanones can be synthesized from 3,5-methoxy phenols via chroman-4-one in three steps or from phloroglucinol. ;Conversion Homoisoflavanes can be obtained from the conversion of homoisoflavonoids. Natural occurrences The homoisoflavonoids portulacanones A, B, C and D can be found in '' Portulaca oleracea'' (common purslane, Caryophyllales, Portulacaceae). The 3,4-dihydroxyhomoisoflavans sappanol, episappanol, 3'-deoxysappanol, 3'-O-methylsappanol and 3'-O-methylepisappanol can be found in ''Caesalpinia sappan''. The homoisoflavones scillavones A and B can be isolated from the bulbs of ''Scilla scilloides'' ('' Barnardia japonica'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonum Odoratum
''Persicaria odorata'', with common names Vietnamese coriander, rau răm (from Vietnamese), laksa leaf (calque from Malay ''daun laksa''), Vietnamese cilantro, phak phai (from Thai: ผักแพว), praew leaf, hot mint, Cambodian mint and Vietnamese mint, is an herb whose leaves are used in Southeast Asian and Northeast Indian cooking. But despite its other name, Vietnamese coriander is unrelated to the mints, nor is it in the mint family Lamiaceae, but its general appearance and fragrance are reminiscent of them. It is also not closely related to coriander (family Apiaceae). ''Persicaria'' is in the family Polygonaceae, collectively known as "smartweeds" or "pinkweeds". The similarities in the tastes and smells between ''Persicaria'' and coriander and mint may be an example of convergent evolution. Food uses The leaf is primarily associated with Vietnamese cuisine, where it is commonly eaten fresh in salads (including chicken salad) and in raw ''gỏi cuốn'', as well ...

Scilloideae
Scilloideae (named after the genus ''Scilla'', "squill") is a subfamily of bulbous plants within the family ''Asparagaceae''. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus ''Hyacinth (plant), Hyacinthus''. Scilloideae or Hyacinthaceae include many familiar garden plants such as ''Hyacinth (plant), Hyacinthus'' (hyacinths), ''Hyacinthoides'' (bluebells), ''Muscari'' (grape hyacinths) and ''Scilla'' and ''Puschkinia'' (squills or scillas). Some are important as cut flowers. Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America. Their flowers have six tepals and six stamens with a Ovary (botany)#Superior ovary, superior ovary, which previously placed them within the Liliaceae, lily family (Liliaceae), and their leaves are fleshy, mucilage, mucilaginous, and arranged in a rosette (botany), basal rosette. The Scilloideae, like most lilioid monocot, lily-like monocots, were at one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agave Tequilana
''Agave tequilana'', commonly called blue Weber agave () or tequila agave, is an agave plant that is an important economic product of Jalisco state of Mexico, due to its role as the base ingredient of tequila. The high production of agavins (branched oligosaccharide, oligosaccharides composed mostly of fructose) in the core of the plant is the main characteristic that makes it suitable for the preparation of alcoholic beverages. The tequila agave is native to the states of Jalisco, Colima, Nayarit, Michoacán, and Aguascalientes in Mexico. The plant favors altitudes of more than and grows in rich and sandy soils. Blue agave plants grow into large succulents, with spiky fleshy leaves, that can reach over in height. Blue agaves sprout a stalk when they are about five years old. These stalks can grow an additional , and they are topped with yellow flowers. The stalk is cut off from commercial plants so the plant will put more energy into the heart. The flowers are pollinated by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
