Phenanthrenoid
Phenanthrenoids are chemical compounds formed with a phenanthrene backbone. These compounds occur naturally in plants, although they can also be synthesized. Phenanthrols Phenanthrols are any of five isomeric phenols derived from phenanthrene (1-phenanthrol, 2-phenanthrol, 3-phenanthrol, 4-phenanthrol, 9-phenanthrol). These molecules can be biomarkers of smoking and/or PAH worker exposure. Chemistry Under UV irradiation, stilbene and its derivatives undergo intramolecular cyclization to form dihydrophenanthrenes. Natural occurrences Phenanthrenes have been reported from flowering plants, mainly in the family Orchidaceae, and a few in the families Dioscoreaceae, Combretaceae and Betulaceae, as well as in the lower plant class Marchantiophyta (liverworts). The rhizome of ''Dioscorea communis'' contains phenanthrenes ( 7-hydroxy-2,3,4,8-tetramethoxyphenanthrene, 2,3,4-trimethoxy-7,8-methylenedioxyphenanthrene, 3-hydroxy-2,4,-dimethoxy-7,8-methylenedioxyphenanthrene, 2- ...

Coelogyne Cristata
''Coelogyne cristata'' is an epiphytic orchid that comes from cool, moist areas of the eastern Himalayas and Vietnam. It blooms every spring, before the snow begins to melt. Its genus name ''Coelogyne'' originates from two Greek language, Greek words, (“hollow”) and (“woman”), because of the orchid’s pistil. ''Cristata'' takes its species name from , the Latin word for “comb”, because of the look of the flower’s lip. Nicknames Although it is better known by its botanical name, ''Coelogyne cristata'' does have nicknames around the world. In Scandinavia and Germany, it is known as the “Snow Queen” because it keeps blooming in the melting snow. It is called ''Schneekönigin'' in Germany, ''Snödrottningorkidé'' in Sweden, ''Snødronning'' in Norway, and ''Lumikuningatar'' in Finland. But the Bulgarians prefer “Angel Orchid” (Ангелската орхидея) because its color reminds them of the clothes of the angel. The Chinese people, Chinese an ...
