picture info	Homoisoflavone 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 portulacanone A, portulacanones A, portulacanone B, B, portulacanone C, C and portulacanone D, 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''.

	Barnardia Japonica ''Barnardia japonica'', the Japanese jacinth, is a bulbous flowering plant in the family Asparagaceae, subfamily 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 ''Hyacinthus''. Scilloideae or ... (also treated as the family Hyacinthaceae). It is one of the two species of the genus ''Barnardia'', found in east China, Korea, Japan, Taiwan and East Russia. Description The plant bears a terminal raceme of pink small flowers. It is said to resemble a fox's tail. The shape of the plant is elegant. Its habitats include open slopes and forest margins. Systematics and taxonomy The genus ''Barnardia'' was created by John Lindley in 1826 together with the single species ''B. scilloides''. However, this species had already been described as ''Ornithogalum japonicum'' by Carl Peter Thunberg in 1784, so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
