摘要：

This paper presents a new technique to determine the lignin and polyphenols contents in Eucalyptus grandis by conventional IR spectroscopy. The calibration standards are milled wood lignin (MW) and native polyphenols. For carrying out the analysis it is necessary to know the traditional Klason lignin and soluble lignin content. The accuracy of this method is good.
