Flickingeria Fimbriata
''Dendrobium plicatile'' is an Asia, Asian orchid species, a member of the genus ''Dendrobium, Dendobium''. It was formerly described as ''Flickingeria fimbriata.'' Distribution The orchid's native regions include Southeast Asia, the Himalayas, and Malesia. It is found in Borneo, Cambodia, South and Central China, Hainan, Himalayas East, India ( Assam), Java, Laos, Lesser Sunda Islands, Nusa Tenggara islands, Malay Archipelago, Malaya, Nepal, Nicobar Islands, Philippines, Sulawesi, Sumatra, Sumatera, Thailand, and Vietnam. Description The methanol extract of ''D. plicatile'' has been shown to scavenge the superoxide anion radical ·O2−. Flower extracts from the closely related species ''Dendrobium officinale'' have also been proven to reduce fatty liver disease, oxidative stress, and inflammation, protecting against alcohol-induced liver injury. From the stems, three phenanthrenes can be isolated, named plicatol A, plicatol B, B and plicatol C, C. The plant also contains th ...

It is found in humid, mossy, mixed and coniferous forests at elevations of 1000 to 1500 meters, in areas with dry winter and a wet spring and summer. The plant has tufted, pendant, subterete, striated, several-noded, white-sheathed stems carrying alternate, fleshy, oblong, acute leaves. Plicatol B is a phenanthrene that can be isolated from the orchid. Flowering The long-lasting, fragrant flowers are found from winter to spring on short to 3" .5 cm single flowered inflorescence that arise from the nodes of leafless canes. The flower size is usually about 2" bout 5 cm The petals are lilac in colour, the sepal A sepal () is a part of the flower of angiosperms (flowering plants).

Dendrobium Moschatum
:''Dendrobium moschatum'' Griff. is a synonym of '' Dendrobium pulchellum''. ''Dendrobium moschatum'', the musky-smelling dendrobium, is a species of orchid. It is native to the Himalayas (northern and eastern India, northern Bangladesh, Nepal, Bhutan, Assam, Yunnan), and Indochina (Vietnam, Thailand, Myanmar, Laos, Cambodia). Plicatol B is a phenanthrene Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with formula C14H10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow. Phenanthrene is used to make dyes, plastics and pesticides, e ... that can be isolated from ''Dendrobium moschatum''.

Dendrobium Rotundatum
''Dendrobium'' is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is a very large genus, containing more than 1,800 species that are found in diverse habitats throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam and many of the islands of the Pacific. Orchids in this genus have roots that creep over the surface of trees or rocks, rarely having their roots in soil. Up to six leaves develop in a tuft at the tip of a shoot and from one to a large number of flowers are arranged along an unbranched flowering stem. Several attempts have been made to separate ''Dendrobium'' into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families. Description ''Dendrobium'' species are mostly epiphytic, or lithophytic although a few species are terrestrial. They are sympodial herbs with cylindrical roots usually arising from the base ...

Phenanthrenoids
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 ...
