Redox2
The effect of this redox reaction from the anthraquinone compound is stabilization of carbohydrates by oxidation of the terminal aldehyde groups of cellulose and hemicellulose (collectively called the peeling process) as well as accelerated delignification through the cleavage of the ß-phenylether bond of lignin. (chemicalproductscorp.com)
In turn, this should allow RedOx to achieve better yields and higher value fuels from a broader range of feedstocks than is currently possible with either acid hydrolysis or enzymatic processes. (greencarcongress.com)
Roots2
Sequential extraction using a cold maceration method and column chromatographic separation of the roots Kniphofia insignis headed to the isolation of three anthraquinones: one monomeric anthraquinone ( 1 ) and two dimeric anthraquinones ( 2 and 3 ). (hindawi.com)
The roots contain a mixture of purpurin (trihydroxy anthraquinone) and munjistin (xanthopurpurin-2-carboxylic acid), and small amounts of xanthopurpurin or purpuroxanthin and pseudopurpurin (purpurin-3-carboxylic acid). (findmeacure.com)
