摘要：

We present details of a modified technique for the extraction of alpha-cellulose from wood samples. The revised technique, based upon the sodium chlorite oxidation method of Green (1963) utilises an ultrasonic bath and small Soxhlet thimbles to prepare alpha-cellulose from slivers of wholewood. These modifications facilitate the rapid batch processing of small wholewood samples to alpha-cellulose and yield a material with sufficient homogeneity as required for palaeoclimatic reconstruction.
