TL;DR: In this paper, the structure of the ligand, β-mangostin was confirmed using NMR and the purity of ligand was determined using HPLC and the synthesised compounds have been characterized using UV-Visible, FTIR and CHNS analyser.
Abstract: The new complexes [CuL₂(H₂O)₂] and [FeL₂(CH₃O)₂] in which L = β-mangostin were synthesised and characterised. The structure of the ligand, β-mangostin was confirmed using NMR and the purity of ligand was determined using HPLC. Both Cu(II) and Fe(II) complexes were prepared by reaction between the ligand and the acetate of the metals in one-step reaction. The synthesised compounds have been characterized using UV-Visible, FTIR and CHNS analyser. Ligand and metal complexes were tested against bacteria to assess on their antimicrobial properties using Minimum Inhibitory Concentrations (MICs) and Minimum Bactericidal Concentrations (MBCs) method. The elemental analysis and spectra data suggested octahedral geometry for both Cu(II) and Fe(II) complexes. The IR spectroscopy revealed that the chelation of Cu²⁺ and Fe²⁺ ion occurred with hydroxyl and carbonyl group at C₉ and C₁ respectively of β-mangostin. Both Cu(II) and Fe(II) complexes showed stronger inhibition against Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumoniae and Salmonella pneumonia at concentration 900 mg/mL and Escherichia coli at 450 mg/mL compared to the ligand itself.

TL;DR: A series of appropriate aminoalkanolic derivatives of xanthone III-VIII was synthesized and evaluated as potential antiarrhythmic agents and tested for the effect on the cardiovascular system.
Abstract: A series of appropriate aminoalkanolic derivatives of xanthone III-VIII was synthesized and evaluated as potential antiarrhythmic agents. They were also tested for the effect on the cardiovascular system. The structure of the synthesized compounds was verified by IR 1H NMR, 13C NMR and mass spectral data.

TL;DR: In this paper, a new xanthone glycoside was isolated as described in Experimental Section, mp 270 °C. It analysed for C2sH360'6 and on hydrolysis with 7% H2S04 gave galactose and glucose (PC) as sugar moieties and an aglycone which was shown to be a Xanthone by its colour reactions and UV spectral data.
Abstract: The rhizome of Acarus calamus Linn. (Fam. Araceae), commonly known as "Butch" is a useful medicinal plant found throughout India, Ceylon and Sikkim. In India it is mostly found in marshy tracts of Kashmir and Sirmon in Manipur, and Nagahills t. Its rhizome has medicinal properties against bed bugs, moths, lice, emetic stomach in dyspep etc?

TL;DR: In this article, various pyrones and flavone, xanthone, and diphenylcyclopropenone react with organic nucleophiles in the presence of phosphorus oxychloride in nitromethane with the formation of the corresponding aromatic cations.
Abstract: Various pyrones and flavone, xanthone, and diphenylcyclopropenone react with organic nucleophiles in the presence of phosphorus oxychloride in nitromethane with the formation of the corresponding aromatic cations, which have been isolated in the form of the perchlorates.
