説明

A new type coumarim (II), C15H16O5, mp 234°, was isolated from rhizomes of Glaucidium palmatum SIEN. et ZUCC., and named glaupadiol. From the experimental results of nuclear magnetic resonance, optical rotatoly dispersion, infrared, and mass spectra, this compound (II) was found to be a mixture of cis and trans forms, and its structure was revealed as 3-hydroxymethyl-8-hydroxy-2, 3, 9-trimethyl-2, 3-dihydrofuro[3, 2-c]-chromen-4-one. The hydroxymethyl group in this compound (II) was bonded to the furan ring in place of the methyl group of racemic glaupalol (I), which was previously isolated from this rhizome.
