In the title compound, C(21)H(15)NO(3), the dihedral angle formed between the aromatic ring systems is 71.50 (3)°. The meth-oxy group is coplanar with the benzene ring to which it is connected, the C-O-C-C torsion angle being 6.37 (17)°. The observed conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring.

The mol-ecule of the title compound, C(16)H(13)NO(2), is almost planar, with a maximum deviation of 0.013 (2) Å from the best plane; the dihedral angle between the two aromatic rings is 1.06 (1)°. In the crystal, mol-ecules are linked through weak intra-molecular C-H⋯O inter-actions, forming chains running parallel to [10].

The present study was designed to find out phytochemical analysis and antimicrobial activity of leaves Mulberry plant. performed on quantitative qualitative basis. basis indicated the presence alkaloids, glycosides, flavonoids, steroids, tannins, saponins Anthraquinone. showed alkaloids (40%), glycosides (20.05%), flavonoids (14%), steroids (3.5%), tannins (11.9%) (11.5%) anthraquinone (0.5%) p...

Aerobic photochemical upcycling of polystyrene plastics into benzoic acid and pharmaceuticals using anthraquinone as the photocatalyst.

Novel anthraquinone-based cyclic antioxidants containing amino, thio and oxo groups were synthesized their antioxidant capacity was determined by using the cerium(IV)-reducing (CERAC) assay. 1H, 13C NMR, FTIR-spectroscopy ESI (Electrospray Ionization) mass spectrometry used for characterization of anthraquinone derivatives exhibiting CERAC capacity. This study is great importance, because compo...

Methanolic extracts of 11 Rumex L. species (Polygonaceae) were examined against brine shrimp and R. scutatus L. has shown significant brine shrimp lethality (LC5O=0.96 |a,g/ml). Methanolic extracts of the roots of R. scutatus were fractionated and the active fraction led to the isolation of 4 anthraquinone aglycones: emodin, chrysophanol, physcion and aloe emodin. Their toxic sequence was found...

Modifying a gold electrode surface with hydroxy-alkyl-thiols significantly reduces the observed rate of electron transfer. This designed and controlled decrease in electron transfer rate readily allows reversible and irreversible electrode processes to be more clearly delineated. Separation of such voltammetric responses can facilitate the direct study of redox catalytic processes, which would,...
