Raman and infrared (IR) spectra of all the fractions were recorded, and it was found that cyanomaclurin, which was one of the fractions and a flavonoid available for biomedical research, showed two characteristic Raman and IR bands in the 750-700 cm-1 wavenumber region. These spectroscopic results show the high potential of these vibrational bands as a marker for rapid detection of cyanomaclurin.Hokkaido University Forests, EFRCDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/53366https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/53366/1/EJFR16-1-04-Shibutani.pdf1345-8221Eurasian Journal of Forest Research16163662013-08engpublisher
