3,4-dihydroxyhomoisoflavan
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 synthetized from 2'-hydroxydihydrochalcones. Homoisoflavanones can be synthetized 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''). ...

Agave Tequilana
''Agave tequilana'', commonly called blue agave () or tequila agave, is an agave plant that is an important economic product of Jalisco, Mexico, due to its role as the base ingredient of tequila, a popular distilled beverage. The high production of sugars named agavins, mostly 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 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 (''quiote'') when about five years old that can grow an additional ; 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 the greater long-nosed bat (and by insects and hum ...
