Acridine is an organic compound and a nitrogen heterocycle with the formula C13H9N. Acridines are substituted derivatives of the parent ring. It is a planar molecule that is structurally related to anthracene with one of the central CH groups replaced by nitrogen. Like the related molecules pyridine and quinoline, acridine is mildly basic. It is an almost colorless solid, which crystallizes in needles. There are few commercial applications of acridines; at one time acridine dyes were popular, but they are now relegated to niche applications, such as with acridine orange. The name is a reference to the acrid odour and acrid skin-irritating effect of the compound.
The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."
Juncus effusus is a perennial herbaceous flowering plant species in the rush family Juncaceae, with the common names common rush or soft rush. In North America, the common name soft rush also refers to Juncus interior.
Dioscorea communis or Tamus communis is a species of flowering plant in the yam family Dioscoreaceae and is commonly known as black bryony, lady's-seal or black bindweed.
Phenanthrenoids are chemical compounds formed with a phenanthrene backbone. These compounds occur naturally in plants, although they can also be synthesized.
Dendrobium nobile, commonly known as the noble dendrobium, is a member of the family Orchidaceae. It has become a popular cultivated decorative house plant, because it produces colourful blooms in winter and spring, at a time when little else is in flower. It is also one of the 50 fundamental herbs used in traditional Chinese medicine, known as shí hú or shí hú lán. Dendrobium nobile is one of the most widespread ornamental members of the orchid family. Its blooms are variegated in colour, shading from white through pink and purple, and the many different cultivated varieties produce different sized and coloured blooms.
Ajmalan is a parent hydride used in the IUPAC nomenclature of natural products and also in CAS nomenclature. It is a 20-carbon alkaloid with six rings and seven chiral centres.
Bulbophyllum umbellatum is a species of orchid. It is native to tropical parts of South Asia, from the west central Himalayas to Taiwan and Indo-China.
Bulbophyllum vaginatum is a species of orchid.
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 words, koilos ("hollow") and gyne ("woman"), because of the orchid's pistil. Cristata takes its species name from crista, the Latin word for "comb", because of the look of the flower's lip.
Maxillaria densa, the crowded maxillaria, is a species of orchid ranging from Mexico south to Nicaragua.
A dihydroxyanthraquinone is any of several isomeric organic compounds with formula C
14H
8O
4, formally derived from 9,10-anthraquinone by replacing two hydrogen atoms by hydroxyl groups. Dihyroxyantraquinones have been studied since the early 1900s, and include some compounds of historical and current importance. The isomers differ in the position of the hydroxyl groups, and of the carbonyl oxygens (=O) of the underlying anthraquinone.
Dihydrostilbenoids (bibenzyls) are natural phenols formed from the dihydrostilbene (bibenzyl) backbone.
Plicatol B is one of the three phenanthrenes that can be isolated from the stems of the orchid Flickingeria fimbriata. It can also be isolated from Dendrobium densiflorum, D. loddigesii, D. moschatum, D. rotundatum and Bulbophyllum kwangtungense
