From the roots ofPrangos ferulacea (L) Lindl. a new coumarin has been isolated, C18H22O5, mp 167.5–169°C (from benzene) [α]16D ± 0° (c 3.88; chloroform), and it has been called pranferin.
By a study of its UV, IR, NMR, and mass spectra and chemical properties, its structure has been established as 8-(2′-acetyl-2′-tert-butoxyethyl)-7-methoxycoumarin.
KeywordsCoumarin Anhydrous Sodium Sulfate Activity Grade Chromium Trioxide Osthole
