Herbacetin
Herbacetin is a flavonol, a type of flavonoid. Glycosides Herbacetin diglucoside can be isolated from flaxseed hulls. Rhodionin is a herbacetin rhamnoside found in ''Rhodiola'' species. Other related compounds Rhodiolin, a flavonolignan, is the product of the oxidative coupling of coniferyl alcohol with the 7,8-dihydroxy grouping of herbacetin. It can be found in the rhizome of ''Rhodiola rosea ''Rhodiola rosea'' (commonly golden root, rose root, roseroot, Aaron's rod, Arctic root, king's crown, ''lignum rhodium'', orpin rose) is a perennial flowering plant in the family Crassulaceae.

Rhodiola
''Rhodiola'' is a genus of perennial plants in the family Crassulaceae that resemble ''Sedum'' and other members of the family. Like sedums, ''Rhodiola'' species are often called stonecrops. Some authors merge ''Rhodiola'' into ''Sedum''. ''Rhodiola'' species grow in high-altitude and other cold regions of the Northern Hemisphere. ''Den virtuella floran'' gives the number of species as 36, the Angiosperm Phylogeny Website gives it as 90, and the ''Flora of China'' gives it as about 90, with 55 in China and 16 endemic there. ''Flora of North America'' lists only three species in the United States and Canada. Description Among the distinguishing characters of the genus are two series of stamens totaling twice the number of petals; free or nearly free petals (not joined in a tube); a stout rhizome from whose axils the flowering stems rise; and a basal rosette of leaves. This genus contains the only species of Crassulaceae that have unisexual flowers. Phytochemistry R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhamnoside
Rhamnose (Rha, Rham) is a naturally occurring deoxy sugar. It can be classified as either a methyl-pentose or a 6-deoxy-hexose. Rhamnose predominantly occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose). This is unusual, since most of the naturally occurring sugars are in D-form. Exceptions are the methyl pentoses L-fucose and L-rhamnose and the pentose L-arabinose. However, examples of naturally-occurring D-rhamnose include some species of bacteria, such as ''Pseudomonas aeruginosa'' and ''Helicobacter pylori''. Rhamnose can be isolated from Buckthorn (''Rhamnus''), poison sumac, and plants in the genus ''Uncaria''. Rhamnose is also produced by microalgae belonging to class Bacillariophyceae (diatoms). Rhamnose is commonly bound to other sugars in nature. It is a common glycone component of glycosides from many plants. Rhamnose is also a component of the outer cell membrane of acid-fast bacteria in the ''Mycobacterium'' genus, which includes the organism that caus ...
