Exempel på hur man kan använda ORCINOL i en mening

• Norman Collie synthesized detectable amounts of orcinol by heating dehydracetic acid with barium hydroxide causing the pyrone ring to open into a triketide.
• Later he made important contributions to the knowledge of dehydroacetic acid (then called dehydracetic acid), describing a number of very remarkable 'condensations,' whereby it is converted into pyridine, orcinol and naphthalene derivatives.
• Erythrolitmin is related to the orceins, and consists essentially of several phenoxazone and orcinol residues.
• His interpretation of the analyses of lecanorin (now called lecanoric acid) went astray because he used an incorrect formula for orcinol and because his lecanoric acid had partially hydrolysed to give orsellinic acid leading to an incorrect result.
• Bial's test is used to distinguish pentoses from hexoses; this distinction is based on the color that develops in the presence of orcinol and iron (III) chloride.
• Ochrolechia lichens produce diverse secondary metabolites, including orcinol depsides, depsidones, and xanthones.
• Chemically, the genus contains an array of compounds including orcinol and ß-orcinol depsides, along with depsidones, dibenzofurans, anthraquinones, xanthones, and chemical derivatives of pulvinic acid.
• In terms of chemistry, Roccella lichens contain orcinol and β-orcinol depsides, as well as aliphatic acids.
• The cortex contains atranorin (responsible for the grey colour), while the medullae of most species have physodic acid, and some species contain other orcinol and beta-orcinol depsidones, including protocetraric acid and physodalic acid.
• Chemically, the cortex of Xanthoparmelia lichens contains either usnic acid or an unknown brown pigment, while the medulla may contain a variety of chemical compounds including orcinol depsides, orcinol depsidones, β-orcinol depsides, β-orcinol depsidones, anthraquinones, aliphatic acids, and amino acid derivatives.
• The main distinctions between Lecidea and Lecidella include Lecidellas typically grey, granular thallus with black, blue-black, or white-grey lower thallus; reproductive structures such as soredia, isidia, and blastidia; common presence of conidiomata; Lecanora-type asci; paraphyses that are not fused and easily dispersed; and secondary metabolites including xanthones, orcinol depsidones, β-orcinol depsides, and triterpenoids.
• Classes of secondary chemicals found in the medulla include orcinol depsides (gyrophoric acid), and beta‐orcinol depsidones (such as protocetraric, salazinic, norstictic, and stictic acids).
• The predominant secondary chemicals present in the genus are orcinol depsides such as lecanoric acid and gyrophoric acid.
• Secondary chemicals produced by the genus include xanthones and the orcinol depside compound sphaerophorin.
• Ochrolechia africana contains several secondary chemicals: the orcinol depsides gyrophoric acid, lecanoric acid, 5-methyl-O-methylhiascic acid, 4,5-di-O-methylhiascic acid, and the xanthone lichexanthone.
• Lichen products are represented in several different chemical classes, including terpenoids, orcinol derivatives, chromones, xanthones, depsides, and depsidones.
