| Abstract: | The aerial parts of Genista pichisermolliana Valsecchi (Fabaceae), an endemic plant of Sardinia, were extracted in Soxhlet apparatus and purified by several chromatographic methods. The new compound alpinumisoflavone 4′-O-glucopyranoside (6) was isolated together with nineteen flavonoids, p-coumaric methylester and d-pinitol, while no alkaloids were detected. All the chemical structures were elucidated by spectroscopic analysis. Since flavonoids represent the main constituents of this plant, the total flavonoid content was determined according to the Italian Pharmacopoeia IX Ed. method. |
