The relative peaks of the PCzC-QDs (R, G, and B) nanocomposite devices were ~2-5 nm red-shifted to PTpC-QDs (R, G, and B) nanocomposite devices, indicating that the recombination zone of electrons and holes in the
carbazole is higher than that of the triphenylamine based nanocomposite.
Antioxidant and radical-scavenging
carbazole alkaloids from the oleoresin of curry leaf (Murraya koenigii spreng).
Murraya koenigii (L.) Spreng (curry patta) has different therapeutic uses and rich source of
carbazole alkaloids.
After seven to eight years, similar excellent color retention is being shown in waterborne masstone formulations for many other organic pigments, including phthalo blue and green,
carbazole violet (pigment violet 23), and quinacridone violet (pigment violet 19).
Analgesic activity of
carbazole alkaloid from Murraya paniculata Linn.
Physicochemical properties were determined using the following methods: phenol-sulfuric acid test [13], a-naphthol reaction [14], iodination reaction [15], Fehling's test [16],
carbazole reaction [17], Fe[Cl.sub.3] reaction [18], and Coomassie brilliant blue reaction [19].
After the first isolation of Murrayanine, 3-formyl-1-methoxycarbazole, a
carbazole alkaloid having antibiotic properties from Murraya koenigii Spreng [1-3], chemists have a significant interest in the field of
carbazole alkaloids due to their interesting structural features and potential pharmacological activities [4-7].
However, work on chemical synthesis of unsubstituted
carbazole is very few, even though chemical synthesis for substituted polycarbazole had already been reported [18-20].
Color pigments include bismuth vanadate yellows, indanthrone blue, isoindoline yellow, monoazo, dairylide and benzimidazolone yellows and oranges, azo and quinacridone reds and maroons; DPP reds;
carbazole violet; phthalo blues and greens.
The fluoren-9-one and
carbazole derivatives were quantitatively the most important compound types in the low polar hetero-compound fraction obtained from the Posidonia Shale bitumens by liquid chromatography.
Curaxins include CBL0137, which is a
carbazole and CBL0102, which is a quinacrine.
According to the companies, Curaxins include CBL0137, which is a
carbazole, and CBL0102, which is a quinacrine.
