Chemical Constituents of Dichloromethane Extract of Cultivated Satureja khuzistanica
Get PDFFour compounds β-sitosterol, β-sitosterol-3-O-β-d-glucopyranoside, ursolic acid and 4′,5,6-trihydroxy-3′, 7-dimethoxyflavone were characterized from the dichloromethane extract of the aerial parts of Satureja khuzistanica (Lamiaceae), a native medicinal plant growing in Iran, on the basis of spectral analysis and comparing with the data in literature. The natural occurrence of these compounds can be conclusive for the chemotaxonomic characterization of the genus Satureja

Microwave-assisted one-pot synthesis of symmetrical 4H-pyran-4-ones
No full textWe report a simple, fast, efficient and benign procedure for solvent-free microwave-assisted one-pot synthesis of symmetrical 4H-pyran-4-ones in the presence of polyphosphoric acid or diphosphorous pentoxide. Various 4H-pyran-4-ones were prepared using this very simple and fast green protocol
