Asplenium Rhizophyllum
''Asplenium rhizophyllum'', the (American) walking fern, is a frequently-occurring fern native to North America. It is a close relative of ''Asplenium ruprechtii'' (syn: ''Camptosorus sibiricus'') which is found in East Asia and also goes by the common name of "walking fern". Description ''Asplenium rhizophyllum'' is a small fern whose undivided, evergreen leaves and long, narrow leaf tips, sometimes curving back and rooting, give it a highly distinctive appearance. It grows in tufts, often surrounded by child plants formed from the leaf tips. The leaves of younger plants tend to lie flat to the ground, while older plants have leaves more erect or arching. Roots and rhizomes It does not spread and form new plants via the roots. Its rhizomes (underground stems) are upright or nearly so, short, about in diameter, and generally unbranched. They bear dark brown or blackish, narrowly triangular or lance-shaped scales which are strongly Glossary of botanical terms#C, clathrate (bearin ...

Caffeic Acid
Caffeic acid is an organic compound with the formula . It is a polyphenol with a key role in scavenging reactive oxygen species (ROS) generated in energy metabolism. Caffeic acid is also one major polyphenol responsible for maintaining normal levels of nitric oxide (NO) within cells. Caffeic acid is a yellow, solid chemical compound that is structually classified as a hydroxycinnamic acid, and the molecule consists of both phenolic and acrylic functional groups. Caffeic acid is found in all plants as an intermediate in the biosynthesis of lignin, a naturally occurring complex carbohydrate representing the principal components of biomass and its residues. It is chemically unrelated to caffeine; instead, the shared name is related to its presence in coffee. Natural occurrences Caffeic acid can be found in the bark of ''Eucalyptus globulus'' the barley grain ''Hordeum vulgare'' and the herb '' Dipsacus asperoides''. It can also be found in the freshwater fern '' Salvinia molest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2-Methyl-2-butanol
''tert''-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic and more recently as a recreational drug. TAA is mostly a positive allosteric modulator for GABAA receptors in the same way as ethanol. The psychotropic effects of TAA and ethanol are similar, though distinct. Impact on coordination and balance are proportionately more prominent with TAA, which is significantly more potent by weight than ethanol. Its appeal as an alternative to ethanol may stem from its lack of a hangover (due to different metabolic pathways) and the fact that it is often not detected on standard drug test. TAA is a colorless liquid with a burning flavor and an unpleasant odor similar to paraldehyde with a hint of camphor. TAA remains liquid at room temperature, making it a useful alternative solvent to ''tert''-butyl alcohol. Production TAA is primarily made by the hydration of 2-methyl-2-butene in the presence of an acidic catal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phellodendron Japonicum
''Phellodendron amurense'' is a species of tree in the family Rutaceae, commonly called the Amur cork tree.
