Lignin and extractive content are important determinants of the pulping quality of wood. Determination of extractive and lignin content using traditional chemical methods is a costly and time-consuming process. Near infrared reflectance (NIR) analysis offers a low cost alternative for prediction of wood quality. Calibrations were developed for the prediction of extractives content, acid-soluble lignin, Klason lignin, and total lignin contents. Each calibration had standard errors of less than 0.6%. Laboratory measurements for a separate set of samples were highly correlated with predicted values (R2 of 0.89 for extractives content, 0.83 for acid-soluble lignin content, 0.97 for Klason lignin content, and 0.99 for total lignin content). It was concluded that NIR analysis is a reliable predictor of extractive and lignin content in Eucalyptus globulus.
