Flavonolignans
Flavonolignans are natural phenols composed of a part flavonoid and a part phenylpropane. Examples Flavonolignans identified in ''Silybum marianum'' (milk thistle) silymarin complex include silibinin, silychristin, silydianin, dehydrosilybin, deoxysilycistin, deoxysilydianin, silandrin, silybinome, silyhermin and neosilyhermin and can be produced in vitro. Silibinin is found in the roots of S. marianum while silyamandin can be found in the fruit. Hydnocarpin can be found naturally in '' Onopordon corymbosum'' and can be synthesised. Scutellaprostin A, B, C, D, E and F can be isolated from '' Scutellaria prostrata'' and can also be synthesized. Hydnowightin can be isolated from '' Hydnocarpus wightiana'' seeds. Three flavonolignans derived from the flavone tricin have been isolated from the herb ''Avena sativa''. Palstatin has been isolated from the Amazon tree '' Hymeneae palustris''. Salcolin A and salcolin B can be found in '' Salsola collina''. Rhodio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silibinin Skeletal
Silibinin (INN), also known as silybin (both from ''Silybum'', the generic name of the plant from which it is extracted), is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silychristin, silidianin, and others. Silibinin itself is a mixture of two diastereomers, silybin A and silybin B, in approximately equimolar ratio. The mixture exhibits a number of pharmacological effects, particularly in the fatty liver, non-alcoholic fatty liver, non-alcoholic steatohepatitis, and there is great clinical evidence for the use of silibinin as a supportive element in alcoholic and Child–Pugh grade 'A' liver cirrhosis. However, despite its several beneficial effects on the liver, silibinin and all the other compounds found in silymarin, especially silychristin seem to act as potent disruptors of the thyroid system by blocking the MCT8 transporter.

Silychristin
Silychristin (also known as silichristin) is a natural product and one of the constituents of silymarin, the standardized, active extract of the fruit of milk thistle, ''Silybum marianum''. It is the second most abundant constituent in silymarin, after silybin.Biedermann, D.; Buchta, M.; Holečková, V.; Sedlák, D.; Valentová, K.; Cvačka, J.; Bednárová, L.; Křenková, A.; Kuzma, M.; Škuta, C.; Peikerová, Ž.; Bartůněk, P.; Křen, V., Silychristin: Skeletal Alterations and Biological Activities. ''Journal of Natural Products'' 2016, 79 (12), 3086–3092. Silychristin is a flavonolignan, along with many other silymarin constituents (such as silybin, isosilybin, silydianin, etc.), meaning it is composed up of a flavonoid and a lignan. It is estimated that up to 65–80% of silymarin extract is made up of flavonolignans, like silychristin, which give silymarin its well known potent antioxidant and hepatoprotective properties. Silychristin can exist as two stereois ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tricin
Tricin is a chemical compound. It is an O-methylated flavone, a type of flavonoid. It can be found in rice bran and sugarcane. Glycosides * Tricin 4'-glucoside (Tricin-4'-O-beta-D-glucopyranaoside, CAS number 71855-50-0) * Tricin 5-glucoside (Tricin 5-O-beta-D-glucopyranoside, CAS number 32769-00-9) * Tricin 7-O-glucoside (Tricin 7-O-beta-D-glucopyranoside, CAS number 32769-01-0) Biosynthesis The biosynthesis of flavones has not yet been elucidated in full; however, most of the mechanistic and enzymatic steps have been discovered and studied. In biosynthesizing tricin, there is first stepwise addition of malonyl CoA via the polyketide pathway and p-coumaroyl Coa via the phenylpropanoid pathway. These additions are mediated by the sequential action of chalcone synthase and chalcone isomerase to yield naringenin chalcone and the flavanone, naringenin, respectively. CYP93G1 of the CYP450 superfamily in rice then desaturates naringenin into apigenin. After this step, it is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avena Sativa
The oat (''Avena sativa''), sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name (usually in the plural, unlike other cereals and pseudocereals). While oats are suitable for human consumption as oatmeal and rolled oats, one of the most common uses is as livestock feed. Oats are a nutrient-rich food associated with lower blood cholesterol when consumed regularly. Avenins are oat gluten proteins, similar to gliadin in wheat. They can trigger celiac disease in a small proportion of people. Also, oat products are frequently contaminated by other gluten-containing grains, mainly wheat and barley. Origin The wild ancestor of ''Avena sativa'' and the closely related minor crop '' A. byzantina'' is '' A. sterilis''. ''A. sterilis'' is a wild oat that is naturally hexaploid. Genetic evidence shows the ancestral forms of ''A. sterilis'' grew in the Fertile Crescent of the Near East. Oats are usually thought to have emerged a ...

Hydnocarpus Wightiana
''Hydnocarpus wightianus'' or chaulmoogra is a tree in the Achariaceae family. ''Hydnocarpus wightiana'' seed oil has been widely used in traditional Indian medicine, especially in Ayurveda, and in Chinese traditional medicine for the treatment of leprosy. It entered early Western medicine in the nineteenth century before the era of sulfonamides and other antibiotics for the treatment of several skin diseases and leprosy. The oil was prescribed for leprosy as a mixture suspended in gum or as an emulsion.

''Scutellaria'' is a genus of flowering plants in the mint family, Lamiaceae. They are known commonly as skullcaps.
