Abstract

The remaining chips from 295 sandalwood (S. austrocaledonicum) cores previously analysed using GC-MS were scanned using Near infrared Spectroscopy (NIRS). The correlation between the NIR spectral data and the a-santalol content from the GC-MS analysis was very high (R2 = 0.9258). Such a high correspondence between these two techniques indicates that it is possible to use NIRS to predict a-santalol content in sandalwood chip samples. The relative advantages of using NIRS for quantifying a-santalol content in raw sandalwood is discussed in terms of its rapid and potentially inexpensive application to quality control for processing and breeding new cultivars.
