title: A new dihydrofuranocoumarin from Opopanax hispidus (Friv.) Griseb.
abstract: Phytochemical investigation of chloroform extract of the aerial parts of Opopanax hispidus afforded a new dihydrofuranocoumarin, 3'-isobutyryl-3'-hydroxymarmesin (1a), together with six known coumarins, oreoselon, peucedanin, officinalin, smirniorin, 4'-acetyl-3'-isobutyryl-3'-hydroxymarmesin and 3'-hydroxyprantschimgin. The structures of the compounds were determined by their comprehensive spectroscopic analysis (IR, EI-MS, (1)H NMR, (13)C NMR, HMBC, COSY, HMBC and HMQC), elemental analysis and comparison with literature data.
